Opis:: This paper presents method of flight dynamics modelling for aircraft encountering trailing vortices generated by other airplane. The mathematical model of 6-DOF spatial motion was applied. Aerodynamic forces produced by a wing were calculated using strip theory method – the wing was divided into a series of chordwise strips and contribution of each strip in these forces was determined. Local angle of attack for each strip was determined taking into account an influence of trailing vortices. Exemplary results of simulations for the case of two straight vortices encountered by aircraft are shown. Incremental contributions to aerodynamic forces and moments of all strips are summed. Model and description of trailing vortices, induced velocity inside the vortex, induced velocity outside the vortex, model of motion dynamics, equations of motion, airplane forces, moments acting on the airplane, aerodynamic forces and moments, trailing vortex effect on the airplane are presented in the paper. In particular, pair of straight trailing vortices, induced velocity for Rankine vortex, strip model of the wing, angle of attack for the strip, airplane pitch angle, bank angle, altitude, trajectory are illustrated.

Opis:: Aircraft range is one of the most important criteria of the assessment of the performance properties of an aircraft. For the needs of the paper the mathematical model of an aircraft (multi-purpose aircraft) and the engine which propels the aircraft was built (turbofan, two-spool, with jet mixer). For the analysis it was chosen so-called typical Breguet model and the conventional range. The models were modified as they should consider the characteristics of the engine in the non-dimensional form. The aim of the simulation research was to discuss the influence of the engine parameters (geometrical and thermodynamic) on the aircraft range, realized mainly in the subsonic and supersonic conditions. The decision which of these conditions can have a significant influence on the selection of the calculating point (i.e. the point which determines the geometrical dimensions of the engine) is difficult as there is no clear direction which aircrafts make up the important share in a mission or missions. It was decided that the parameter which connects the engine geometry with the range model is so-called non-dimensional coefficient of engine geometry which is the relation of the area on the inlet to the engine related to the wing area of the aircraft. It was shown that for various parameters of the engine cycle it is possible to show such a value of the non-dimensional coefficient of geometry which maximizes the aircraft range. The results obtained show opposite requirements as for the engine geometry for the subsonic and supersonic flight. On this basis the compromise solution was proposed to fulfil the requirements of the multi-purpose aircraft.

Opis:: Composite materials are increasingly being used in aviation. Specific stiffness and strength of composite materials (especially CFRP laminate, sandwich structure) are higher compared to metal alloys. They are beneficial features of materials used in aviation. Mass reduction of aircraft structures (e.g. due to the use of composite materials) contributes to an aircraft’s better performance in terms of its range, top speed and ceiling and consequently causes an increase in airplanes capacity. Moreover, the use of high-strength and lightweight materials in aviation contributes to longer life time and lower exploitation costs. The aim of the paper was the study the possibilities of replacing the aluminum spar of an airplane wing with a composite structure. In order to compare the mass and strength of the aluminum with the composite spar, the global shell and local solid models were created and finite elements analysis was performed. The analysis was carried out for the front spar of the wing of the agricultural aircraft PZL-106.

Opis:: The choice ofparameters of designed airplane should take place according to rational rules, allows to evaluate of project-variants. In spite of the evidence of this ascertainment, both the theory and the designing practice concentrates on the methods of seeking of solutions, and the problem of valuing is maximized simplified, and sometimes outright vulgarized. During that time, it is criteria and limitations determine the form of unknotting, and in the effect about the commercial success of all undertaking. The schema of the general designing of the airplane permits to restore approximate conditions for the real work of the airplane. Obtained results substantially are relative to "depths" of the modelling of the airplane characteristic (accuracy of partial models), the end result is a compromise. Authors worked out the software for different types of airplanes obtaining probable results of calculations. The main elements of the definition of the projects task, the full and reduced morphological board, the partial model, the mathematical model of the airplane are illustrated in the paper.
Wybór parametrów projektowanego samolotu powinien odbywać się według racjonalnych zasad, pozwalających wartościować warianty projektowe. Mimo oczywistości tego stwierdzenia, teoria i praktyka projektowania koncentruje się na technikach szukania rozwiązań, zaś problem wartościowania jest maksymalnie upraszczany, a czasem wręcz trywializowany. Tymczasem, to kryteria i ograniczenia stanowią o postaci rozwiązania, a w efekcie o sukcesie handlowym całego przedsięwzięcia. Schemat ogólnego projektowania samolotu pozwala odtworzyć warunki zbliżone do rzeczywistego funkcjonowania samolotu, Uzyskane wyniki w dużym stopniu zależą od "głębokości" modelowania właściwości samolotu (precyzji modeli cząstkowych), rezultat końcowy jest wynikiem kompromisu. Autorzy opracowali oprogramowanie dla różnych typów samolotów uzyskując prawdopodobne wyniki obliczeń. Główne elementy definicji zadania projektowego, pełna i zredukowana tablica morfologiczna, model cząstkowy oraz model matematyczny samolotu są zilustrowane w artykule.

Opis:: The need for the increase of speed, range and the useful load of general air transport is presently more actual than ever. In direct conjunction with these factors is the aircraft fuel efficiency. Determination of the fuel quantities used up in aircraft motions both in the air and on the ground has very essential meaning in the analysis of economics of the air transport. Reducing the amount of fuel consumed involves knowing the effect of alternate profiles and procedures on fuel consumption or fuel flow for the various aircraft types operating in the system. The aviation community is striving to provide more fuel efficient operations in the system. Critical to many of the efforts is the ability to estimate fuel consumption. A methodology of SFC (specific fuel consumption) valuation relating to aircraft performance and actual flight profile is the main goal of the work. Aircraft fuel consumption model consist of two submodels. The first is the aircraft computational model, with several submodels: geometrical, aerodynamic, mass, power unit. The second is utilization model, namely transport operation model. The calculations were done for few different categories airplanes. Final results and recommendations based on the analysis of fuel consumption and transportation energy effectiveness are presented in conclusions.
Potrzeba zwiększania szybkości, zasięgu i ładunku użytecznego transportu lotniczego jest obecnie bardziej aktualna niż kiedykolwiek. Wiąże się z tym sprawność wykorzystania paliwa. Określenie ilości paliwa zużywanego przez samolot poruszający się zarówno w powietrzu jak i na ziemi ma bardzo istotne znaczenie w analizie ekonomiki transportu. Minimalizacja ilości zużytego paliwa wymaga przeprowadzenia analizy wpływu profilu i procedur wykonywania lotów na wymaganą ilość paliwa w zależności od typu samolotu funkcjonującego w systemie transportowym. Firmy lotnicze dążą do wykonywania zadań z maksymalną efektywnością z punktu widzenia zużycia paliwa. Dla wielu z nich najważniejszym zadaniem jest, więc możliwość wiarygodnego oszacowania zużycia paliwa. Głównym celem pracy było opracowanie metody wyznaczania zużycia paliwa w zależności od rodzaju samolotu i profilu lotu. Aby zrealizować ten cel opracowany został odpowiedni model matematyczny składający się z dwóch pod-modeli. Pierwszy z nich to kompleksowy model obliczeniowy samolotu, drugi zaś, model użytkowania. Z wykorzystaniem tych dwóch modeli wyznaczone zostały wskaźniki oceny efektywności samolotów różnych kategorii wykonujących typowe zadania transportowe. Na podstawie analizy porównawczej wyników, sformułowane zostały wnioski dotyczące optymalnych zakresów użytkowania samolotów z różnymi rodzajami napędu oraz optymalnych profilów przelotowych.

Opis:: The aim of the article is to find the relationship and dependencies between the mission parameters of the multi-role aircraft (altitude, flight velocity, thrust load) and the parameters that define the flow of the turbofan engine. The conclusions of these studies are relevant at the stage of preliminary engine design. There was built the model of thermal cycle of low bypass. The model of an airplane was simplified to its aerodynamic characteristics. The mission was divided into air tasks (stages) such as a take-off, a climb at a certain velocity, sub and supersonic flight and maneuvers (i.e. turn). Dimensionless energy criteria binding both the engine and aircraft parameters were introduced. There were conducted the simulation studies of the model airplane-engine mission to show the part of the mission that "dimensions " the engine. The results were limited to the presentation of the impact of circuit parameters such as T3, π, μ on the defined criteria. The calculations were carried out for a number of selected missions defined in the literature as Loll, HiLoHi and HiHiHi. The comparison of the energy requirements of these missions was done. There were pointed out these criteria of the mission evaluation that may affect making decisions at early design stages. There were designated the areas of design variability in an engine meeting the criteria for energy mission. The advantage of this model is universal character of dimensionless criteria, whereas the disadvantage is the need to build complex models of the engine and the assumption at the outset aerodynamic characteristics of the aircraft. The originality of the presented solution is to show an alternative, unconventional approach to the design process (not as so far) the engine itself but the entire aviation system.

Opis:: In the article the analysis of the influence of design parameters of the engine on the performed by the multirole aircraft mission was performed. The problem is complex as a result of performing a series of manoeuvres in various conditions of flight. A special feature of multi-role aircraft mission is a sudden (even pulse) weight change and exactly its reduction as a result of the discharge of cargo bomb, rocket or due to the consumption of ammunition during air combat manoeuvring. Reducing the airplane mass by the weight of the fuel consumed (continuously) and the used weapons radically differ the demands on the energy required to overcome gravity and drag forces. The article shows how the reduction of the aircraft mass influences on the change of the thrust load factor. It was built the mathematical model of the system engine-aircraft-air job (taking into account the flight conditions, elements of the mission - subsonic and supersonic flight, flight time, the heat-and-gasdynamic and mass model of the engine). The model enables for the simulation research of the complex flight missions and their evaluation on the basis of the constructed criteria. The model includes a parametric description of physical processes in the turbofan engine, thus provides a direct assessment of the impact of selection of engine parameters on the effectiveness of the mission. The results of calculations according to classical criteria (e.g. kilometre fuel consumption, specific fuel consumption) were presented. The paper presents new criteria, which enable to analyze the energy consumption of the complex mission of the aircraft (e.g. energy consumption: the unit range, the degree of utilization of energy resources and the carried out the mission engine). Criteria were built in by combining the parameters necessary for the flight with disposable ones. On the basis of these parameters there was done an assessment of the "quantitative" adjustment of a power unit to various missions such as subsonic, supersonic and mixed (for different their proportion), for different levels and the plane range. The results were presented in a pictorial way on numerous charts.

Opis:: Research in the field of fracture mechanics and determination of material characteristics are used for practical purposes, such as the assessment of static and dynamic strength of structural components, analysis of their fatigue life or extending the life span of their operation. A structural component, considered to be safe from fatigue cracking point of view, was investigated and results were presented in this article. In particular, an analysis was made to determine the stress intensity factor for the cracked wing flap construction, based on static and fatigue tests, using the Irwin-Kies theory. The flap with a service crack was subjected to fatigue tests with a load similar to the one registered during flight measurements. The flap without a service crack was subjected to static tests, after cutting the cracks of specified lengths and shapes (similar to the service crack) in the skin of the flap. The article presents changing the length of the flap crack in subsequent load cycles, change in the maximum values of force and the crack opening displacement in subsequent load cycles, dependence of P-COD in the first and second stage of fatigue testing of the wing flap, dependence of the wing flap compliance on the length of the crack and experimentally determined dependence for wing flap. The occurrence of a flap crack up to approximately 230 mm does not cause a significant growth of the stress intensity factor.
