Opis:
The analysis of passenger transport, being made in recent years, indicate that Poland is one of the fastest developing countries in Europe, also in this aspect. It is envisaged that GA traffic will increase until 2012 by approximately 4 % annually. More and more people use air transport, the amount of available connections is increasing as well as the amount of passengers served. Such development we owe, first of all, to entering Poland into the European Union and full opening of polish airspace. All this constitute great opportunity to firms and air traffic operators but also considerable challenge in the form of necessary adaptation of infrastructure to market demands. It is assumed that further development of air transport in Poland will be supported by liberalization of air traffic law regulations, both domestic and international, including liberalization of international agreements, which would make possible construction of new airports, opening new connections and entering into polish marketplace new air carriers. Indispensable condition of proper utilization of growth potential is constant development of airport infrastructure and increasing effective usage of airspace in a way, which ensures necessary capacity to intensifying air traffic.
Analizy przewozów pasażerskich w ostatnich latach wskazują, że Polska jest jednym z najszybciej rozwijających się krajów Europy. Prognozuje się, że ruch GA będzie wzrastał średnio o 4% rocznie do 2012 roku. Coraz więcej osób korzysta z transportu lotniczego, zwiększa się liczba połączeń i obsługiwanych pasażerów. Rozwój ten zawdzięczamy przede wszystkim wejściu Polski do Unii Europejskiej i pełnemu otwarciu polskiego nieba. To ogromna szansa dla przedsiębiorstw jak i operatorów lotniczych, ale także istotne wyzwanie polegające na konieczności dostosowania infrastruktury do potencjału rynku. Zakłada się, że dalszemu rozwojowi przewozów lotniczych w Polsce sprzyjać będzie liberalizacja prawa lotniczego zarówno krajowego, jak i międzynarodowego, w tym liberalizacja umów międzynarodowych, umożliwiająca budowę nowych lotnisk, otwieranie nowych połączeń i wkraczanie na polski rynek nowych przewoźników. Warunkiem właściwego wykorzystania potencjału wzrostu jest ciągły rozwój infrastruktury lotniskowej oraz zwiększanie efektywności wykorzystania przestrzeni powietrznej w sposób zapewniający niezbędną przepustowość dla rosnącego ruchu lotniczego.

Opis:
The work concerns the analysis of the possibilities of using light aircraft in the regional passenger transport. This analysis was based on the existing airport infrastructure in Poland. Between 43 existing airports with paved runways and length more than 1,000 meters potential routes of aircraft traffic were set. The study compared the light aircraft transport to the car transport. One of the benchmark criteria was the travel time between different destinations, using both means of transport. The second criterion is the financial aspects of travel. For this purpose, a statistics of light aircraft and calculated their Direct Operating Cost as a function of various parameters such as maximum weight, the number of passenger seats, cruise speed were created. Analysis also included air navigation charges on the routes and the operator profit. The calculations allowed identifying potential routes where the plane would be competitive with the car in terms of travel time and costs by one person. The number of these routes was dependent on the speed of travel, the number of seats on the plane as well as the fill factor of these seats. The analysis also applies to determine the number of passengers traveling between the regions. In 2013, domestic air transport handled less than 2.5 million passengers, which in comparison to the countries of Western Europe is a poor result. This is caused mainly by a small amount of domestic routes as well as a small number of regional airports. The implementation of the concept of using light aircraft in regional connections aims to increase the speed of travel, increase the safety in passenger transport, cost reduction and partial replacement of road transport by air transport.

Opis:
It should be noted that for reasons of state security (the so-called “national interest”), the transport of VIPs using military aircraft has a lower acceptable level of risk than is the case for other passengers. Consequently, the regulatory documents relating to these transport operations regulate a much broader and more detailed range of issues than is the case for other passenger transport operations, taking into account the principle of ‘safety first’. The regulations contained in the regulatory documents for the carriage of the most important persons in the state on military aircraft are intended to safeguard against human error, which may affect the possibility of an aviation event occurring during such operations. The regulatory documents also deal with additional requirements for equipment needed on military aircraft carrying VIPs, to reduce the risk of incidents, and a more in-depth analysis of environmental factors to reduce the safety risks due to adverse weather conditions.

Opis:
It should be noted that due to the good of the state (the so-called “national interest”), in the case of transport of VIPs by military aircraft, its acceptable level of risk is lower than in the case of transportation of other passengers. Thus, normative documentation regarding such transport regulates a significantly wider and more extensively indicated range of issues, including the principle of “security above all”, when compared to transportation of other passengers. The regulations contained in the normative documents concerning transportation of state VIPs by military aircraft are to protect them not only from human errors which may have influence on the occurrence of air incidents in the course of such transportation. Normative documents also regulate additional requirements regarding aviation equipment employed to transport state VIPs by military aircraft (to decrease the risk of failure) and an in-depth analysis of environment factors (to decrease the risk related to threats to security of transportation due to unfavourable atmospheric conditions).

Opis:
One of the most important factors in the development of modern civilization has become the increase in the significance of mobile and fast means of transportation of people and cargo. Aircraft as the fastest available means in the entire transportation system is the basis in places where the distance in the transportation of people is long and the travel time is short. The present work focuses on passenger transport in the European area using light transport aircraft, which may complement existing air transport and can become a real alternative to those who travel by other means of transport. The system of local transportation will become competitive in relation to other means of transport and will find its place on the market only when it has the highest indicators of efficiency. It can be reached by optimally obtaining passenger aircrafts fleet structure performing transportation tasks and optimizing its functioning. One of the basic problems is the rational selection and use of aircrafts, i.e. the minimization of their quantity while at the same time guarantee complete performance of transporting tasks. The selection of the best method of using the means of transport is connected with a large number of alternative variants, which makes it necessary to use special methods of searching for optimal solutions. The quality of the aircraft fleet should be estimated on the basis of several criteria when taking into account the difference in performing tasks. The way to design a competing aircraft fleet is to choose its characteristics by using advanced methods of multiple objective optimization. This work presents the methodology of the optimal designing of the aircraft fleet using the multitask character of the matter which is based on multiple objective mathematical programming in the concept of the set theory.

Opis:
Celem wszystkich przedsiębiorstw jest osiągniecie jak najwyższej efektywności ekonomicznej. Dotyczy to także przewoźników lotniczych. Jednym z obszarów, w którym istnieją możliwości poprawy tej efektywności jest zmniejszenie kosztów eksploatacji posiadanych środków technicznych, głównie samolotów. W tym zakresie oczywistym wydaje się zmniejszenie zużycia paliwa przez samoloty. Aby w procesie tym osiągnąć zadowalające wyniki konieczne jest zidentyfikowanie czynników zewnętrznych oraz parametrów eksploatacyjnych mających największy wpływ na to zużycie. W artykule przedstawiono wstępną analizę wpływu tych wielkości na zużycie paliwa transportowego samolotu odrzutowego. W tym celu dokonano analizy poszczególnych faz lotu samolotu z uwzględnieniem czynników mających najistotniejszy wpływ na zużycie paliwa. Przedstawiono także najważniejsze parametry pracy samolotu rejestrowane w czasie jego lotu oraz dokonano wstępnej analizy ich wpływu na zużycie paliwa. Przedstawione opracowanie należy potraktować jako wstępne do bardziej zaawansowanych analiz optymalizacyjnych zużycia paliwa w samolotach odrzutowych.
Every enterprise aims at maximizing economic yield, including air carrier enterprises. Optimization of direct operating costs related to aircraft operation is a key contributor to economic yield. Fuel consumption constitutes the biggest single direct operating cost for all air carriers, therefore its optimization is of utmost importance. Identification of environmental factors and flight data parameters affecting it is crucial. This article presents initial analysis of selected environmental factors and flight data parameters influencing fuel consumption for distinctively selected flight phases. Analysis given below should be treated as preliminary, giving introduction to the more advanced elaborations.

Opis:
Airplane wing load control systems are designed for modification/redistribution of aerodynamic loads in order to decrease risk of structural damage in conditions of excessive loads, to improve passenger comfort in turbulent atmosphere or to act as flight control systems. Classical examples include systems involving symmetric deflections of ailerons reducing wing root bending moments (Lockheed C-5 Galaxy) or deflections of spoilers stabilizing landing approach path (Lockheed TriStar). The fast development of Micro Electromechanical Systems and their application in Flow Control System opens the perspectives of designing practical wing load control systems based on fluidic actuators, modifying local aerodynamic loads by inducing changes to flow, for example, by inducing flow separation in the boundary layer or modifying Kutta condition on the trailing edge. This is the principle of operation of novel concepts of flow control actuators proposed by Institute of Aviation and discussed in the paper. The systems include actuators in the central part of the wing section, reducing local lift similarly to classical spoilers and actuators on the modified trailing edge, acting similarly to ailerons. The potential advantages in comparison to classical devices include potentially shorter reaction time because of avoiding the necessity of moving large surfaces against high dynamic pressure, which is important in conditions of fast-changing loads in turbulent atmosphere.

Opis:
Dynamic analyses of a transport aircraft landing gear are conducted to determine the effort of such a complex system and provide capabilities to predict their behaviour under hazardous conditions. This kind of investigation with the use of numerical methods implementation is much easier and less expensive than stand tests. Various 3D models of the landing gear part are defined for the multistage static FE analysis. A complete system of the main landing gear was mapped as a deformable 3D numerical model for dynamic analysis with the use of LS-Dyna code. In this 3D deformable FE model, developed in a drop test simulation, the following matters were taken into consideration: contact problems between collaborating elements, the phenomena of energy absorption by a gas-liquid damper placed in the landing gear and the response of the landing gear during the touchdown of a flexible wheel with the ground. The results of numerical analyses for the selected drop tests and the results from the experiments carried out on a real landing gear were used for verification of FE models and a methodology of the landing gear dynamics analysis. The results obtained from the various simulations of the touchdown have proved the effectiveness of the 3D numerical model and how many problems can be solved in the course of only one numerical run, e.g. geometric and material nonlinearities, a question of contact between the mating components, investigation of the landing gear kinematics, investigation of the energy dissipation problem in the whole system and the stresses influence on the structure behaviour, which can appear in some elements due to overload.

Opis:
The challenge to the manufacturer or service provider is how to assess and define true customer expectations and then how to design, manufacture and sell the product to best meet those expectations. Each product must provide operational capabilities, which allow military forces to maintain technical and logistic superiority over a potential adversary even if it is just natural or induced environment, which can be expected over the operating and maintenance portion of life cycle. Battle damage repair is a critical factor in managing operation. We acknowledge that traditional cost minimizing measures are not always central and other performance measures such as time of repair, reliability and availability become more relevant. Assessing aircraft damages in the field and making appropriate decisions on the reparability, making repairs at the lowest repair level possible and evaluating airworthiness of subsequent repairs is critical to the air forces maintaining its force projection capability. Among other, combat damage of helicopters, damaged areas and erosion on leading edges of the compressor first stage rotor blades, achievable and optimum solution, goal function – duration minimisation, goal function – cost minimisation are presented in the paper.

Opis:
Numerous cases of self-activation of the SSP-FK aircraft fire suppression system (including commissioning of valves and extinguishing tanks) testify about the fact that it is not yet fully understood in the technical aspect, and because of the performed role on the aircraft is the basic element to ensure flight safety. Solving problems with false fire signalling of the SSP-FK system is an important issue for the safe operation of aircraft and military helicopters, because it is preventive (to warn the crew of the possibility of fire) and rescue system (aiming at extinguish the fire) in each phase of a flight. In addition, the SSP-FK system is used on many types of military aircraft (including helicopters from W-3/3W/3WA/3PL and Mi/8/14/17/24 family as well as An-28 and Tu-154M aircraft. The paper presents selected results of work in the Air Force Institute of Technology in the study of SSP-FK fire suppression system (as one of the main protection systems on-board) used on many types of military aircraft operated in the Polish Armed Forces. In determining the conditions of the false signalling of fire, simulation models of action blocks implementing of the SSP-FK fire suppression system were developed. The research on simulation models was performed in Matlab-Simulink and Circuit-Maker computing packages. The results of these works were used to diagnose selected modules and blocks of the SSP-FK system during the study of actual cases of their false activation.

The general direction of development of all types of aeronautical propulsion systems, and also of these produced a long time ago and exploited for many years, is their permanent " upgrade" in the new equipment and of methodic of the current technical state checking for the purpose of the indispensable flights safety assurance, the prolongation of the failure-free exploitation time - but also the maintenance of the economic concurrency requirements. Recently, a categorical form receives the requirement of the noise limitation of aviation power plants and the limitation for emission of toxic elements in exhaust. In the piston engines, the direction of developments are aimed on the design of compression ignition engines, fuelled with standardized aircraft jet fuel. Their additional valour is their smaller fuel expenditure, about 30% less with respect to their spark ignition equivalents. Particularly important is the task of decrease the quantities of fuel used up, the limitation of number of produced engines through raising their efficiency and durability, limitation of noisiness of engines alone and driven: propellers, ventilators and the lifting rotors of helicopters, the limitation of thrust, required to the flight of the airplanes and the helicopters. One turned attention on ecological requirements, which force the application of mineral fuels completed by biofuels.

Opis:
For the needs of fuel-injection system development for the experimental detonation combustion chamber with a rotating detonation (PoiG - Project: "Turbine engine with detonation combustion chamber") a series of experiments with injection of kerosene under a high speed air stream was performed at the Institute of Aviation. The proper preparation of combustible mixture is very important for the initiation and sustenance of a rotating detonation. The task in case of kerosene-air mixture is far more difficult than for mixtures of hydrogen-air or kerosene-oxygen. A simple stream injector has been tested as a base system, and the kerosene was injected perpendicular to the air stream vector directly from the plane wall of the constant cross-section channel. The process of injection and atomization of kerosene was observed in the special transparent visualization chamber, enabling the spray observation of two mutually perpendicular directions. In subsequent experiments air pressure, air temperature and air flow velocity as well as and injection pressure of kerosene were varied. The tested process was photographed and, in case of chosen experiments, filmed using a high-speed digital camera. The surveys were aimed at identifying and assessing of following parameters of fuel atomization process: the range of the fuel stream and filling grade of research channel with aerosol, aerosol homogeneity and the size of forming it droplets, the possible presence of fuel streams flowing down the walls of channel. The resulting photos allowed for more comprehensive, but only a qualitative assess of the spraying process, while the filmed small regions of visualization chamber allowed the counting down and dimensioning of droplets. This paper presents a test facility and measuring techniques applied during the research activity and selected results of carried out tests.

Opis:
Poland, as a member of the EU, is represented within the ICAO, by the European Aviation Safety Agency. However, this does not relieve our country from the responsibility of developing a state safety programme (SSP). The need to set up such a programme, which has to be specific to every country involved in aviation operation, was introduced by the ICAO’s Annex 19. One of the important points in Annex 19 is: “5.2.1 Each State shall establish and maintain a safety database to facilitate the effective analysis of information on actual or potential safety deficiencies obtained, including that from its incident reporting systems, and to determine any actions required for the enhancement of safety”. The Polish Civil Aviation Authority, along with other databases, manages the European Coordination Centre for Aviation Incident Reporting Systems (ECCAIRS). The authors (who are specialists dealing with exploitation processes in aviation) have conducted a laborious processing of the data contained in the ECCAIRS database, analysing them based on various criteria: aviation occurrence categories (as defined by the ICAO), phases of flight for different airports in Poland etc. Aircraft with an maximum take-off mass (MTOM) 5,700 kg (commercial aviation) were considered separately. It was found that the most events are those that relate to power plant (SCF-PP) airframes and related system (SCF-NP) failures, followed by collisions with birds (BIRD), events related to airports (ADRM) and events related to the required separation of aircraft (MAC). For lighter aircraft, the dominant categories are ARC, CTOL, GTOW and LOC-I events. The article presents a proposed method for predicting the number of events, determining the alert levels for the next years and assuming a normal distribution (Gaussian). It is one of the first attempts to use actual data contained in the database of events on airports in Poland. The results of this analysis may support the decisions of supervisory authorities in the areas where security threats are most important.

Opis:
Travel is an inseparable part of human life. It is connected not only with private life but also with business life. People want to travel more, farther and faster. That is why air transport is currently one of the fastest-growing areas of passenger transport, and airlines carry more and more passengers from year to year. Due to the growing negative impact of air transport on the natural environment, research aimed at the development of technologies to reduce the negative impact of air transport is becoming more and more important. One of the possibilities for improving the situation is the use of alternative energy sources, limiting the emission of greenhouse gases into the atmosphere. The paper aimed to analyze the meaningfulness of replacing the classic power unit in a light transport aircraft with a hybrid, combustion-electric power unit. Analyzes were made with the use of simulation methods for the PZL M-28 aircraft.

Opis:
Resonances of the „ wings torsion " mode shapes to a large extent depend on the structural parameters of the wing, and more specifically to the existence or not of fuel tanks at the wings ends, munitions hard points or engines mounted on the wings. In the paper the group of resonances is presented with mode shapes in which the one, two or three node aircraft wing torsion is present. It is shown in the paper, that these vibration mode shapes consist both of fuselage bending or torsion. Resonance frequencies with mode shapes in which one, two or three node wing torsion occurs depend fundamentally on existence of wing hardpoints. If hardpoints are occupied by fuel tanks, these frequencies are varying continuously in wide range. The various interesting from cognitive point of view combinations have place then, including variable frequencies and variable mode shapes as a function of fuel consumption. The aim for the analysis of 3 cases of resonance a wing torsion mode shapes of airplanes and gliders was to investigate the relationships and mechanisms that are taking place and operate between the torsioningl vibration of the wings and bending or torsion vibrations of the fuselage. Recognition of these phenomena should facilitate the researcher to understand and search effectively and explore the resonances of„ wing torsion " mode shapes.

Trzy obszary diagnostyki: genezowanie, kontrola stanu i prognozowanie wymagają wiedzy o możliwych uszkodzeniach statków powietrznych. Uszkodzenia zmieniają procesy użytkowania samolotów i śmigłowców. Mają one wpływ na bezpieczeństwo lotów. W pracy opisano wpływ uszkodzeń na proces użytkowania statków powietrznych. Omówiono problematykę uszkodzeń załączając przykłady charakterystycznych uszkodzeń. Artykuł koncentruje się na rodzajach niesprawności i uszkodzeń oraz fizyce i diagnostyce uszkodzeń. Odpadnięcie górnej części pokrycia kadłuba samolotu w czasie podejścia do lądowania, korozyjno - zmęczeniowe pęknięcie belki skrzydła, udziały procentowe uszkodzeń w podziale na specjalności lotnicze i przyczyny wypadków lotniczych, udział procentowy uszkodzeń w różnych fazach lotu samolotów, złomy zmęczeniowe łopatek sprężarki i turbiny oraz dysku turbiny silnika odrzutowego są przedstawione w artykule. Uszkodzenia pierwotne stanowią podstawę do wnioskowania statystycznego o trwałości i niezawodności elementów i zespołów lotniczych. Uszkodzenia wtórne są rejestrowane jako skutki uszkodzeń pierwotnych. Dla praktyki eksploatacyjnej najbardziej przydatna jest klasyfikacja uszkodzeń elementów, która umożliwia makroskopową ocenę postaci uszkodzenia oraz domniemanej przyczyny jej powstania.
Three basic areas of diagnostics: genesis, checking of condition and prognosis should be developed including the aeronautical applications. This we to be realized because of a number of new destructive agents as the ageing of complication of software systems and automatic control systems even when the level of reliability of the systems is very high. But one should rate the increasing of failures costs as a part of all operators. The paper concentrates on kinds of inefficient and damages and on the physics and diagnostics of damages. Upper-fuselage skins separated in the course of approach, corrosion and fatigue induced fracture of a wing beam, percentage of damages/failures attributable to particular aeronautical branches and causes of air accidents (military aviation per one year), percentage of damages/failures at different stages of aircraft flight, fatigue fractures of compressor and turbine blades of a turbojet engine. Primary damages determine base for the statistical conclusion on durability and dependability of elements and air-sets. Secondary damages are registered as results primary damages. For the exploitive practice most useful is the classification of damages of elements which makes possible the macroscopic estimation character of the damage and supposed reason its appearance.

Opis:
Blended Wing Body concept offers several advantages compared to traditional aircraft tube and wing concept. The advantages mainly come from the distributed aerodynamic and structural loads, which leads to better aerodynamic performance as well as lighter structural weight. Most of the existing studies were focused on big transport aircraft carrying 400 to 800 passenger. In this study, a conceptual design of a business jet aircraft applying blended wing body concept is carried out. The market forecast for this category of aircraft can reach up to 24000 aircraft in the next 20 years. The possibility of having larger cross section is one of the competitive advantages, notably in a long-range flight. The requirement stated was to fly a trans-atlantic flight and carrying up to 18 passengers. It has to have a low floor height permitting easy passenger access. The design process consists of initial weight estimation, initial sizing, and preliminary aerodynamics, weight and balance and performance analysis. Some design consideration specially related with Blended Wing Body concept will be discussed, i.e. take-off and landing aerodynamics, structural concept, stability and control. The final design resulted in twin-engine aircraft, a Maximum Take-off Weight of 44 ton, cabin floor area of 6.9 x 10 m, winglet and split rudder for directional stability and control, and elevons for longitudinal and lateral control.

Opis:
Międzynarodowy Port Lotniczy im. Jana Pawła II Kraków- Balice to port lotniczy, który rozwija się bardzo dynamicznie. Z roku na rok liczba obsłużonych pasażerów wzrasta. Z tego względu lotnisko jest ciągle rozbudowywane. Pod koniec roku 2016 oddano do użytku nowy terminal pasażerski, a obecnie zakończono remont płyty postojowej. Celem artykułu jest przeprowadzenie analizy wykorzystania płyty postojowej przed rozpoczęciem prac budowlanych i reorganizacji płyty. Obliczenia miały na celu sprawdzenie wykorzystania płyty, a w przyszłości porównania analiz sytuacji sprzed i po remoncie płyty. Analizę wykonano na podstawie udostępnionych danych zawierających informacje o liczbie operacji lotniczych zarejestrowanych w ciągu okresu jednego roku, rzeczywistych oraz rozkładowych czasach operacji lotniczych – przylotów i odlotów wraz z przydzielonym numerem stanowiska postojowego na płycie lotniska. Przeprowadzono analizę wykorzystania poszczególnych stanowisk w całym analizowanym okresie oraz wielkości czasów postoju samolotów na płycie, w tym z podziałem na linie lotnicze tradycyjne oraz niskokosztowe. Przeanalizowano wykorzystanie płyty i jej poszczególnych stanowisk w dniu, w którym lotnisko przyjęło największą liczbę samolotów. W podsumowaniu zawarto najważniejsze wnioski z przeprowadzonej analizy oraz wyliczone wartości charakteryzujące: wykorzystanie płyty w dniu o największej liczbie operacji, zajętość poszczególnych stanowisk w badanym okresie, średnie czasy postojów samolotów na płycie.
Kraków John Paul II International Airport is an airport that is developing very dynamically. The number of serviced passengers increases year by year. For this reason, the airport is constantly being extended. At the end of 2016, a new terminal was opened, now also the apron is being renovated. The article is to analyse the use of the apron before construction works and reorganization of the plate. The calculations were made to check the apron use and, in the future, to be able to compare them with the analysis of the renovated apron. The analysis was performed on the basis of the data containing information on the number of aviation operations registered during one year, including actual and scheduled times of flight operations – arrivals and departures along with the allocated number of the parking stand at the apron. The analysis includes the usage of apron and its individual aircraft stands throughout the entire analysed period and the size of aircraft standstill times, including the division into traditional and low-cost airlines. The use of the apron and its individual stands on the day of the largest number of aircrafts accepted by the airport was analysed. The summary contains the most important conclusions from the analysis and the calculated values that characterize: the use of the apron on the day with the largest number of operations, the occupancy of individual positions in the examined period, the average aircraft standstill times.

Opis:
The aim of the research is to test the fuel additives which decrease dimensions of atomised fuel drops, by applying changes to the specific parameters which impact the atomisation process. Those parameters include density, surface tension, viscosity and the viscosity index. Dimensions of drops of biofuels are much bigger compared to hydrocarbon fuels. By modifying the physical and chemical parameters of biofuels, dimensions of drops in an atomised fuel stream should become smaller. Those dimensions play a major role for the level of emissions of hydrocarbon and carbon monoxide, as well as mainly nitrogen oxides and particulates. The research on emissions of toxic components of fuel is relatively advanced today in the field of piston combustion engines, especially for use in car vehicles. However, the dynamic development of the air transport brings more pressure on the issue of toxic emissions in the case of aircraft engines. The level of toxic emissions from aircraft engines may be from ten up to even several thousand times greater than the level of emissions from piston engines. The issue of how biofuel additives can affect the process of fuel atomisation and thus enable the control over the atomisation to obtain the smallest possible drops leading to reduced nitrogen oxides emissions is a new and original issue. The reduced nitrogen oxides emissions in the case of biofuels is of utmost significance because, according to latest knowledge, those levels are increasing.

Opis:
Among the most important problems faced by the air transport today there can be mentioned some negative influences of aircraft and airports on the environment and the increasing costs of air transport. One of the possibilities to improve the situation is to work out innovative solutions aimed at decreasing of the aircraft pollution and improving the transport effectiveness. Among the most innovative ideas is the use of magnetic levitation (MAGLEV) to aid the take-off and landing of the transport aircraft. The “Integrated Ground and on-Board system for Support of the Aircraft Safe Take-off and Landing” – GABRIEL, deals with radically new integration of the MAGLEV technology into the air transportation system that contains aircraft, airport, air traffic control, authority, logistic and operational support, maintenance, etc. GABRIEL idea includes operation of the aircraft without the conventional undercarriage system and using the ground based power and supporting systems for take-offs and landings. In case of using the GABRIEL system as a catapult, the aircraft on the track must be accelerated to the speed permitting to reach the altitude of 300 m or more. Such take-off and climb results in minimum noise and minimal emission of substances harmful for the environment. After reaching the altitude of 300 m, the aircraft may follow its flight with using different flight strategies. Different conditions of the unconventional take-off needs to shape other way the trajectory of the initial stage of the aircraft flight after the lift-off. The aim of the present work was to determine the optimal conditions of the lift-off and the optimal trajectory of the initial climb minimizing the emission. Simplified realization of the Ritz- Galerkin method was used in this work, which uses an approximate solution to boundary value problems for determining the optimal flight trajectory.

The article presents selected results of the analytical work carried out in the Air Force Institute of Technology in the field of information visualization capabilities of helmet-mounted guidance and navigation in fighter aircraft MiG- 29. There is presented the SzCz-3UM headset system of target’s indication, currently used on-board of MiG-29, which is directly cooperating with the pilot during the combat flight. There was presented that the information from the onboard systems of this aircraft containing analogue devices must be computer-processed into digital form in order to present flight data in the helmet-mounted display system. However, MiG-29 aircraft, used in the Polish Air Force, are equipped with modern digital avionics (integrated avionics system) based on the MIL-1553B digital data buses, which gives the possibility of the new helmet-mounted imaging of flight parameters via the computer data processing from aircraft’s devices and on-board installations. To develop guidelines for the construction of the helmet-mounted system for the MiG-29, the SWPL-1 Cyklop flight data-displaying system was adopted (system developed in the Air Force Institute of Technology as avionics system modernization for Mi-17 military helicopters). There are discussed the main problems of scientific and specialist research positions used in the Air Force Institute of Technology to assess the accuracy of the selected equipment components of avionics systems and determine credibility of information provided to the pilot during the flight.

Opis:
The increase in air traffic requires organizational changes at the airport and near the airport. To ensure appropriate airport operating efficiency, it is becoming necessary to provide unobstructed flow of information between all parties involved in the process. Common decision-making process regarding operations carried out at an airport, based on legible information, may contribute to faster and more precise prediction of sequence of events. This article aims to present pre-departure sequencing method in the terms of the dynamic growth of airports. This method dynamically defines current sequencing of departing aircraft with consideration of time required to maintain minimum separation between subsequent take offs and evaluates runway occupancy regarding planned arrivals. Developed method uses criteria of reduction maximum delay on one handling position, which is starting runway in use. It is carried out by sequencing tasks, in accordance with non-decreasing requested times of completion. Greedy algorithm has been used to define sequence of carrying out take off operations based on the earliest possible time of the departure. Faced with dynamic growth of airports, this method may contribute to improvement of predictability of events, and thus facilitate proper decision making, which will allow managing airport traffic smoothly and without unnecessary downtimes.

Opis:
Ostatnie lata wskazują na dynamiczny rozwój coraz to lepszych technologii bezzałogowych statków powietrznych RPAS/UAV (ang. Remotely Piloted Aircraft Systems/Unmanned Aviation Vehicle), potocznie nazywanych „dronami”, których terminologia wywodzi się z regulacji Organizacji Międzynarodowego Lotnictwa Cywilnego (ICAO). Zainteresowanie ich eksploatacją wzrasta nie tylko do celów militarnych, ale też cywilnych, w tym komercyjnych. Celem artykułu jest analiza kierunku rozwoju bezzałogowych statków powietrznych i zaprezentowanie aktualnych możliwości wykorzystania nowych technologii w transporcie lotniczym. Analizując omawiane trendy, autorzy skorzystali m.in. z materiałów udostępnionych na oficjalnych stronach instytucji nadzorujących transport lotniczy, jak również światowych organizacji nawiązujących do tematyki objętej obszarem rozważań zawartych w niniejszym artykule. Trendy światowe idą w kierunku rozwoju nowych technologii, co daje lepsze możliwości techniczne. Problematyczny staje się jednak stan regulacji prawnych, jak również niski poziom świadomości potencjalnych użytkowników. W opinii ekspertów jest jeszcze wiele do zrobienia zanim UAV zostaną wprowadzone do użytku publicznego na szeroką skale. Wiąże się to z wieloma czynnikami. Jednym z nich jest edukacja w nowej dziedzinie lotnictwa cywilnego, z czym wiąże się przygotowanie odpowiednich kadr zarządzających tymi systemami.
Recent advances in Remotely Piloted Aircraft Systems/Unmanned Aviation Vehicle technologies are on the rise. They are popularly called ‘drones’ and their terminology derives from ICAO regulations. The interest in drone exploitation involves not only military but also civilian and commercial areas. The aim of this article is to give an insight into the development direction of remotely piloted aircraft and present current possibilities of using new technologies in air transport. The authors of the article used the subject of research literature analysis method including the sources available on the official websites of the air transport inspecting authorities, as well as world organizations relating to the subject matter analysed in this article. Recent advances in new technologies are on the rise, which offers potential. The condition of law regulations as well as low awareness of the potential users is, however, problematic. According to experts, there is still much to be done before UAV are mass-produced. It is connected with numerous factors. One of them is education in the new branch of civil aviation, which involves senior personnel training.

Opis:
Wykonywanie transportu lotniczego, jak również prowadzenie działalności na terenie portów lotniczych, odpowiada za zanieczyszczenie środowiska hałasem, który utrudnia funkcjonowanie i ma wpływ na życie ludzi i zwierząt. W artykule omówione zostały sposoby redukcji emisji wysokich dźwięków do środowiska, których źródłem są przede wszystkim statki powietrzne, a także funkcjonowanie lotnisk. Przeprowadzone badania wskazały, że stosowane są liczne rozwiązania, które ograniczają emisję hałasu. Wprowadzenie i wykorzystanie nowych technologii, a także rozwiązań technologicznych do walki ukierunkowanej na obniżenie hałasu zarówno w sposób czynny, jak i bierny, pociąga za sobą zmniejszenie negatywnego wpływu hałasu na środowisko.
The air transport as well as the service provided at airports is responsible for noise emission to the local environment, which hinders the functioning and living, of both, people and animals. The paper shows the potential solutions aimed at reducing the emission of high sounds to the environment, which are primarily caused by aircraft, as well as the activities and functioning of airports. The conducted research has shown that there are numerous solutions which may lead to decrease of the noise emission. Just the introduction and use of new technologies, as well as technological solutions have an impact on the reduction of noise, both in an active and passive way. Undoubtedly both have an impact on its reduction and entails a reduction of its negative impact on the local environment. The aim of this study was to characterize the methods, the solutions which can be use either at airports, or in their surroundings or in aircraft’s construction, which allows to reduce the noise emission to the local environment by air transport. The article is a response to the research problem, which was.

Opis:
Solutions for turbulisation of a part of laminar boundary layer upstream of shockwave on laminar airfoil in transonic flow were investigated by means of solution of Unsteady Reynolds-Averagd Navier-Stokes equations using as a closure the four-variable Transition SST turbulence model of ANSYS FLUENT solver. This turbulence model has the capability of resolving laminar-turbulent transition occurring in undisturbed flow as well as under the influence of flow-control devices. The aim of the work was to investigate possibilities of improvement of aerodynamic characteristics of laminar wing of a prospective transport aircraft in adverse conditions characterised by occurrence of a shockwave over a laminar-turbulent transition region with separation of laminar flow under the shockwave. The subject is important for application of laminar flow technology, offering economic and environmental advantages due to decreased friction drag, into civil transport aviation. Natural laminar-turbulent transition in the investigated conditions takes place with occurrence of “laminar separation bubble” under the foot of a shockwave and the resulting shockwave is intensive and prone to unsteady oscillations, the “buffet” phenomenon, limiting operational range of flight parameters. In order to counteract the harmful effects of natural laminar-turbulent transition in transonic flow two types of turbulators, placed upstream of the shockwave, were investigated. One of them consisted of delta-shaped vortex generators, producing chordwise-oriented vortices. The other consisted of rectangular micro-vanes, perpendicular to flow and to airfoil surface producing vortices of rotation axes oriented spanwise. Effectiveness of both types of turbulators was investigated for varying height and their location on airfoil chord. Both types of turbulators have proved their effectiveness in tripping laminar boundary layer. The specific effects of the tutbulators, different for each type occurred in the region where laminar separation takes place on clean airfoil. As a result, the changes of lift and drag were different for each type of turbulators.

Opis:
Simulations of ice accretion on airfoil in icing conditions were conducted using ice accretion model implemented by authors in ANSYS FLUENT CFD solver. The computational model includes several sub-models intended for simulations of two-phase flow, determination of zones of water droplets impinging on the investigated surface, flow of water in a thin film on airfoil surface and heat balance in air-water-ice contact zone. The method operates in an iterative loop, which enables determination of effects of gradual deformation of aircraft surface on airflow over the surface, which has impact on distribution of collected water, flow of water film over the surface and local freezing rates. The implementation of the method in CFD solver made it necessary to complement the mathematical model of determination of local rates of deformation of aircraft surface with modification of computational mesh around the surface, which must conform, to the deformed surface. Results of simulated ice accretion on NACA 0012 airfoil were compared with results of experiment conducted in icing wind tunnel for a 420 s long process of ice accretion in steady-flow, steady angle-of-attack conditions. Close agreement of values and location of maximum ice thickness obtained in experiment and in the flow, simulations can be observed. For the airfoil deformed with ice, contour determination of its aerodynamic characteristics at several other angles of attack was conducted proving dramatic degradation of its aerodynamic characteristics due to ice deformation.

With a growing number of coronavirus patients worldwide, military and civilian transport aircraft are increasingly being used for civilian medical evacuation duties (MEDEVAC) on time-critical flights. This article deals with the possibility of converting an aircraft fleet in the Czech Republic to MEDEVAC. The indication for the analysis of the possibility of transforming transport aircraft was the past and current pandemic situation in the Czech Republic. The main research question is how to implement the modification of a selected airline of the Czech Republic to MEDEVAC. An analysis of the technical data of selected aircraft from Airbus and Boeing was used to investigate this problem. Further, an analysis of the medical equipment required for the MEDEVAC aircraft category was also performed using equipment manufactured in the Czech Republic. The results obtained by the analysis and spatial arrangement of the aircraft deck for the transport of patients with medical equipment confirmed the possibility of such a transformation within the Czech Republic. We consider it important to elaborate on a project that would solve, in detail, all the steps of the conversion of a transport aircraft to MEDEVAC.

Opis:
Dynamically growing number of airline passengers and flights, especially intercontinental ones, is a key factor conducive to the spread of infectious diseases. The threat to public health may be even more noticeable if it is taken into account, that the developing countries record larger increase in air traffic than most European high developed states with good sanitary conditions. The aim of the study is to make a review of the literature concerning risk assessment and ways to prevent transmission of infectious diseases aboard civil aircrafts. Airline-associated spread of infectious diseases can refer to airborne and vector-borne diseases, as well as these transmitted by fecal-oral route. The particular danger of rapid spread of a disease through airline passengers is caused by influenza virus strains with the potential for causing pandemics or coronaviruses that are infectious agents of MERS and SARS. Passengers suffering from active tuberculosis are also a reason of a serious epidemiological concern. Also other airborne diseases like measles can be easily transmitted by air transport when travelling from endemic countries. On the other hand, flight-related food poisonings are less and less frequent – the most common cause are still bacteria of the Salmonella genus. Among vector-borne diseases, particular attention is paid to the problem of possible transfer of mosquitoes infected with West Nile Virus. In the prevention of the spread of communicable diseases via air transport, there are important factors such as: efficient identifying of sick travellers and crew members, use of personal protective equipment (such as masks with HEPA filter) by passengers travelling alongside sick person, efficient ventilation inside the passenger cabin, proper disinfection of aircrafts' interiors, vaccination of cabin crews against influenza and proper preparation and handling of catering provided to aircrafts.

Opis:
Simulations of two-phase flow cases consisting of air and water dispersed in atmosphere were conducted using ANSYS FLUENT solver. The computational model was built with the aim of determination of zones of water droplets impinging on the investigated surface, which is a first step towards simulations of ice accretion in flow conditions where super cooled water is present as dispersed phase. It follows Eulerian approach, currently most effective approach for determination of distribution of water collection on two- and three-dimensional surfaces. Dispersed water is treated as continuous phase and its transport equations are being solved along with air flow equations in the whole computational domain. There are two specific factors of this two-phase flow problem. One of them is ratio of air and water density, which is a cause of existence of two time scales in obtaining a numerical solution of this problem: one for convergence of air flow solution and another for solution of flow of dispersed water in the computational domain. This required development of a specific strategy in obtaining a numerical solution in some circumstances important in aerodynamics, especially at high angle of attack with flow recirculation zones on the wing. The other factor is relatively low concentration of water droplets in conditions important for atmospheric icing. The consequence of this is possibility of uncoupling of solution for both phases and narrowing the solution of the phase of dispersed water to a small region of non-uniformity of velocities of the dispersed phase. Results for two objects: an airfoil and helicopter tail rotor blade, exploiting the developed computational strategy will be presented.

Opis:
Air transport is subject to various risks. One of them is bird strike hazard. Despite numerous regulations concerning prevention from this type of occurrence, it is not possible to eliminate them entirely. Bird strikes most often take place during take-off and landing, that is on or in the vicinity of an airport. For that reason airport operators are the first parties that can be made accountable for this occurence. International law imposes numerous responsibilities on airport operators in terms of bird strike hazard prevention on air operations, thus placing airport operators in a “key position” in the system of safety. However, the party that suffers significant damages in the first instance, is the aircraft operator. If a bird strike takes place on or in the vicinity of an airport, an aicraft operator can sue the airport operator for compensation of damages. Generally, the issue of indemnity is subject to out of court negotiations, however instances in which there is a lack of agreement between the parties, i.e. airport operator, aircraft operator or their insurers, lead to legal proceedings for compensation. This article attempts to illustrate the relationship between air traffic participants such as airport operators and aircraft operators in connection with their obligations and liability, particulary taking into account the legal obligations of an airport operator.
Transport lotniczy narażony jest na różnego rodzaju zagrożenia. Jednym z nich jest zagrożenie zderzeniem z ptakami. Pomimo licznych regulacji prawnych dotyczących zapobiegania tym zdarzeniom, nie jest możliwe całkowite ich wyeliminowanie. Najczęściej zderzenia z ptakami mają miejsce w trakcie startu i lądowania, czyli na lotnisku lub w jego okolicy. Dlatego zarządzający lotniskiem jest pierwszym podmiotem, który może zostać pociągnięty do odpowiedzialności za to zdarzenie. Prawo międzynarodowe nakłada na zarządzających lotniskiem liczne obowiązki w zakresie zabezpieczenia operacji lotniczych przed tym zdarzeniem, czyniąc go tym samym kluczowym podmiotem systemu bezpieczeństwa. Podmiotem, który w pierwszej kolejności doznaje znaczących szkód jest z kolei przewoźnik lotniczy. Jeżeli zderzenie z ptakami wydarzy się w strefie portu lotniczego lub jego pobliżu, przewoźnik może dochodzić pokrycia szkód od zarządzającego portem lotniczym. Generalnie kwestia odszkodowania jest przedmiotem pozasądowych negocjacji, jednakże w razie braku porozumienia pomiędzy stronami, tj. portem lotniczym, przewoźnikiem lub ich ubezpieczycielami pozostaje droga sądowego dochodzenia odszkodowania. W artykule podjęto próbę pokazania relacji pomiędzy zarządzającym lotniskiem a przewoźnikiem lotniczym w kontekście ich obowiązków i odpowiedzialności, ze szczególnym uwzględnieniem przewidzianych przepisami prawa obowiązków zarządzającego portem lotniczym.

The article’s aim was to compare an ecological effectiveness of a common jetliner with 189 passenger capacity flying on two CFM engines and a very light jet business aircraft designed to carry up to 8 people on board. The carried-out analysis showed that the NOx emission per passenger in Very Light Jet (VLJ) is three times higher than in common jet airliner, furthermore there is 15 times difference in CO emission. Based on the results of the analysis, it can be stated that it is appropriate to extend the certification of engines to smaller units, as well as to adjust the LTO test beyond laboratory conditions.

Environmental impacts due to aviation operations in the vicinity of airports have become a serious concern to the community. A variety of techniques can be employed to reduce the noise impacts of aircraft. Continuous Descent Approach (CDA) is the new promising technique, which can significantly reduce noise impact by keeping aircraft higher and at lower engine thrust for longer by eliminating the level segments in conventional "step down" approaches. These procedures (implemented in different ways) are fixed routes that are vertically optimized. With the changing traffic, conditions and variable noise abatement rules the benefits of CDA operations are not yet fully realized. Actually, at many airports, CDA techniques are implemented for environmental improvements. This article presents the concept of optimized CDA. The modified flight procedure has been shown in measurement and analysis for Warsaw International Airport example. In this demonstration test, the procedure was shown to reduce the A-weighted noise level for the selected location along the flight path for different aircraft. Depending on aircraft type, the noise benefit from a CDA compared to a conventional approach was up to about 9.5 decibels (this change is noticeable to the human ear). Measurements have shown that Continuous Descent Approach have the potential for significant environmental benefits including reductions in noise.

Opis:
The evaluation of the effects of transport collision often takes the form of ground reconnaissance. Undoubtedly, remotely piloted aircraft systems (RPAS) can support and help the police, firefighters, security agents and paramedics in the event of a transport collision. Although there is a scarce amount of literature concerning the use of RPAS in crisis management, it is important to pay more attention to the benefits of this technology. The article describes the danger of collisions, as well as discusses the possibility of using RPAS, their functionality and potential utility. Sensors installed on RPAS can rapidly identify the place of the accident, the number of casualties, the type of damaged vehicles or the type of contamination.

Opis:
A mathematical model for simulation of icing dedicated to simulation of ice accretion and its effects on aircraft aerodynamic characteristics in conditions of rime icing is presented. Pure rime icing occurs at lower temperatures than glaze icing and results in higher roughness of the surface of deposited ice. The model accounts for increased surface roughness, in terms of equivalent sand grain roughness, caused by deposited rime ice, which influences generation and dispersion of heat in the boundary layer. Increase of surface roughness is determined by analytical models created upon experimental data obtained in icing wind tunnels. Increased generation of heat is a result of increased tangential stress on the surface and is quantified in the temperature recovery factor determined numerically by a CFD solver. Effects of surface roughness on the intensity of forced convection are quantified by application of Colburn analogy between heat and momentum transfer in the boundary layer, which allows assessment of heat transfer coefficient for known friction coefficient, determined by CFD. The computational method includes determination of the surface distribution of mass of captured water in icing conditions. The model of freezing of captured water accounts for generation of heat due to latent heat of captured water droplets, temperature recovery in boundary layer and kinetic energy of captured droplets. The sinks of heat include forced convection, heating of super cooled droplets, conduction of heat through the ice layer and sublimation. The mathematical model is implemented as user-defined function module in ANSYS Fluent solver. The results include effects of deposited ice, including increased surface roughness on aerodynamic characteristics of an airfoil.

Opis:
Model Predictive Control (MPC) is a model-based control method based on a receding horizon approach and online optimization. A key advantage of MPC is that it can accommodate constraints on the inputs and outputs. This paper proposes a max-plus general modeling framework adapted to the robust optimal control of air traffic flow in the airspace. It is shown that the problem can be posed as the control of queues with safety separation-dependent service rate. We extend MPC to a class of discrete-event system that can be described by models that are linear in the max-plus algebra with noise or modeling errors. Regarding the single aircraft as a batch, the relationships between input variables, state variables and output variable are established. We discuss some key properties of the system model and indicate how these properties can be used to analyze the behavior of air traffic flow. The model predictive control design problems are defined for this type of discrete event system to help prepare the airspace for various robust regulation needs and we give some extensions of the air traffic max-plus linear systems.
