Opis:
The article discusses the automatic control system of the Diamond DA42 aircraft anti-icing system. In the analysis of the issue of icing, four parameters were taken into account: air temperature, cloud humidity, temperature of the aircraft and precipitation. On the basis of the initial parameters, the authors determined the icing intensity, which is likely to occur on the aircraft skin. By automating the activities related to the activation of the de-icing system, it is possible to significantly relieve the pilot and increase the safety of air operations, particularly in conditions, which are conducive to the formation of icing. The authors performed a thirty-minute electronic simulation of the flight in real atmospheric conditions. The article discusses the obtained results of the simulation. Designed system uses fuzzy logic. The system inputs and output were determined and fuzzy expert inference system was developed in MATLAB software and Fuzzy Logic Toolbox. The proper system work was verified with use of MATLAB/Simulink software. Use of that kind of systems can significantly relieve the pilot and increase the safety of air operations, particularly in conditions, which are conducive to the formation of icing.

This paper presents numerical analysis of airplane motion parameters during wing in-flight icing. The wing external flaps deflection event was taken under consideration. The mathematical model of the airplane motion including twelve ordinary differential equations was employed. Using available publications as well as TS-11 “Iskra” jet trainer geometrical and mass relationships, a computer code evaluating motion parameters of an iced airplane was developed. On the basis of analysis results, conc- lusions referring airplane dynamic properties during wing ice accretion was formulated.
Praca przedstawia wyniki numerycznej analizy parametrów ruchu samolotu podczas symetrycznego oblodzenia skrzydła oraz usterzenia wysokości w czasie lotu. Pod uwagę wzięto również przypadek wypuszczania klap zaskrzydłowych w czasie występowania oblodzenia. Zastosowano klasyczny model matematyczny dynamiki ruchu samolotu, opisany przez układ dwunastu równań różniczkowych pierwszego rzędu. W odniesieniu do wiadomości zaczerpniętych z literatury oraz danych geometrycznomasowych samolotu TS-11 „Iskra” opracowano program komputerowy do wyznaczania parametrów ruchu z uwzględnieniem oblodzenia samolotu. Na podstawie analizy wyników przedstawiono wnioski opisujące własności dynamiczne samolotu wykonującego lot w warunkach oblodzenia.

Opis:
Currently, overhead lines dominate in the Polish medium and low voltage distribution networks. Maintaining their high reliability constitutes a very important challenge, especially under the severely changing climate conditions. An overhead power line exposed to high ice and rime loads has been considered. Using the finite element method (FEM), mechanical reliability of the distribution infrastructure was examined under various atmospheric conditions. Loads under the stressful conditions of rime, ice and wind were determined for the weakest section of the 30 kV overhead line, which consisted of concrete poles and ACSR conductors. SAIDI and SAIFI reliability indices and costs were determined for several variants of object reconstruction. The results allowed for determination of a solution relying on relocating the cables of all lateral branches and main line ice protection, through a system based on a weather-coordinated increase of the electrical load. To verify the solution proposed, a field experiment was conducted. The experiment confirmed the effectiveness of the solution proposed that appears to be universal. The paper is a result of synergic cooperation of two academic teams, i.e. a mechanical and electrical power engineering one, and the Distribution System Operator (DSO).

The impact of winter addition of salts to roadside soils was studied for the national road No. 28 in Poland, in Małopolska Region. The measured sections of the road No. 28 are two access ways to the city of Grybów. According to instructions of GDDiKA (General Directorate for National Roads and Motorways) both sampled routes: Grybów–Gorlice (sampling section G-G) and the section Nowy Sącz-Grybów (N-G) were included in II standard of winter road maintenance. The general increase in soil salinity, chloride concentration and pH values from the roadside soils was evidenced by the difference of results of two sampling campaigns, before and after winter season of 2015/16. Salinity indicators showed significant increase, even though weather winter season 2015/16 was rated as mild and road de-icing salts were applied at less-than-average rate. Soil hydraulic properties were calculated estimated from soil texture using pedo-transfer functions for estimating the dynamics of salts into soils, suggesting easy leaching of salts from topsoil.

Opis:
Icing of aircrafts and their powerplants is essential danger for safety of flights and is at the bottom of many more or less serious aviation incidents and accidents in Poland and worldwide. Icing of aircraft turbojet, turbofan, turboprop and turboshaft engines may occur not only at negative temperatures of air but at positive temperatures too. Ice detectors of anti-icing systems of aircrafts are located on airframes, mainly in front of a fuselage, on upper surface of wings or under its and do not detect of gas turbine engines icing early enough. The manual turning on of anti-icing system of engine is necessary. Icing of aviation gas turbine engines is at the bottom of mechanical damaging of blades and vanes, stall and surge of compressors, flameout, roll-back or shut down of engines by control systems. There is mechanical, pneumatical, electrical and mixed ice protection systems used in turbojet, turbofan, turboshaft and turboprop engines for their protection against icing. Hot air ice protection systems are mainly used in turbojets and turbofans. These systems are supplied by air from high pressure compressor. These kind of ice protection systems do not operate in all offlight conditions because of severe danger thrust or power reduction due to a recirculating of air in the hot air ice protection system. However, usually anti-icing systems protect engines effectively; accidents and incidents are caused by errors of crew and ground personnel members mainly.
Oblodzenie statków powietrznych i ich zespołów napędowych stanowi istotne zagrożenie dla bezpieczeństwa lotów i jest przyczyną wielu bardziej lub mniej zdarzeń i wypadków lotniczych w Polsce i na świecie. W odróżnieniu od płatowca oblodzenie lotniczych silników turbinowych może zachodzić już w dodatnich temperaturach otoczenia. Czujniki instalacji przeciwoblodzeniowych rozmieszczane są na płatowcach, głównie w przedniej części kadłuba, na górnej powierzchni skrzydeł lub pod nimi, a nie ma ich we wlotach silników, co nie umożliwia odpowiednio wczesnego wykrycia oblodzenia elementów silników, w związku z czym wymagane jest ręczne włączanie instalacji przeciwoblodzeniowych silników. Oblodzenie lotniczych silników turbinowych jest przyczyną mechanicznych uszkodzeń łopatek, niestatecznej pracy sprężarki, a nawet do samoczynnego wyłączenia się silnika lub wyłączenia go przez układ sterowania. W celu zabezpieczenia lotniczych turbinowych silników odrzutowych, śmigłowych i śmigłowcowych przed oblodzeniem stosuje się mechaniczne, powietrzne, elektryczne i mieszane instalacje przeciwoblodzeniowe. W silnikach odrzutowych najczęściej wykorzystywane są cieplne instalacje zasilane gorącym powietrzem pobieranym ze sprężarki wysokiego ciśnienia. Instalacje tego rodzaju nie mogą pozostawać włączone we wszystkich fazach lotu, ponieważ np. pobieranie powietrza ze sprężarki do instalacji przeciwoblodzeniowej obniża ciąg lub moc silnika. Działanie tych instalacji zazwyczaj jest skuteczne, a wypadki i katastrofy spowodowane oblodzeniem silników jest zwykle wynikiem błędów popełnianych przez załogi lub członków personelu naziemnego.

Opis:
Atmospheric icing poses a threat for safety in many areas of transport, especially in air transport and exerts harmful impact on operation of external sensors and mechanisms of aircraft, ships and land vehicles. In order to investigate phenomena leading to ice accretion on sensitive parts of objects exposed to icing conditions numerical simulation models are in use. These models are typically composed of submodels dealing with a fragment of the complex phenomenon of ice accretion and its interaction with external flow. A practical approach to simulation of icing process is to divide it into three problems being solved interactively: 1) simulation of two-phase flow of air and dispersed supercooled water and determination of distribution of mass of water hitting the object’s surface, 2) determination of conditions on the surface collecting supercooled water from the external flow and simulation of freezing and water film flow, and 3) modification of computational grid as a consequence of change of shape of the surface with deposits of ice. A simulation system directed at investigation of atmospheric icing on moving object is being developed as an extension of capabilities of a commercial CFD code ANSYS FLUENT. Solutions of two-phase flow of air and dispersed water with specific boundary conditions enabling the determination of distribution of water hitting the surface, as well as results of modelling of water film flow on the surface will be presented. The system of equations describing the transport of the dispersed water consists of the continuity and momentum equations. It is assumed, that interactions between the phases are onedirectional, i.e. the air flow influences the water droplet flow and not vice-versa. It is also assumed that the water film velocity distribution is linear in direction normal to surface. This way, both phenomena are being described with first order partial differential equations with respect to space and time and the solution approaches may be similar.

Opis:
Icing on the overhead contact line exclude the possibility of efficient current collection from the overhead contact line. The effects oficing can result in losses for carriers due to delay or cancellation of trains and also cases of damage to the traction infrastructure and pantographs. Th e existing methods of de-icing the traction network (mechanical, chemical and electrical) are currently ineffective. Therefore, it is necessary to develop a new electrical method that takes into account the detailed current flow in the overhead contact line. This article presents a model for calculating the current flow in the overhead contact line and the resistances of droppers, suspension elements, and distance holders measured on the basis of actual measurements.

Opis:
One consequence of the declining ice cover in the Arctic is increased areas of open seas. These new open sea areas lead to some challenging aspects related to ship stability. Longer fetch lengths, associated with build-up of larger waves followed by increased conditions for sea spray icing on vessels is one aspect. Open seas in combination with cold atmospheric temperatures is a prerequisite for polar low pressures to occur. Polar lows may represent an additional aspect of increased icing on vessels by heavy snow in addition to extensive sea spray ice accretion. Over the last decades, different formulas for prediction of sea spray ice accretion rate on ships were developed to form basis for ice accretion warnings. Some of these formulas seem to have certain limitations and appear to be conservative. Important limitations of some formulas are considerations regarding heat flux, relationship between wind and waves, and ice accretion related to Polar lows. This paper will take a closer look at the accuracy and the realism of different ice accretion formulas and, related to this aspect, we will also discuss whether ship officer candidates receive sufficient maritime education and training (MET) related to realistic ice accretion and ship icing aspects.

This study investigates the current trace elements concentrations of snow and de-icing using ICP-MS, and phytotoxicity using three vascular plants in snow. The study assesses the contamination, classification and phytotoxicity of snow quality removed from roads of residential areas and piled on children’s playgrounds in residential territories. The research found that according to Russian environmental quality standard for water has been identified the exceeding trace elements in snow by W, Se, Mn, Cu, V, Mo, Ni and Zn. The pollution indices (PLI, CF and Zc) were identified pollution level of snow piles from moderate contamination to very high contamination. Based on average germination index values for Sinapis alba L., Lepidium sativum L., and Triticum aestivum L., the degree of inhibition in snow piles varied from no inhibition to strong inhibition. The trace elements content in de-icing “Galit А” and salt sand mix are defined in the following descending order: Zn > Mn > Ba > V > Rb > Sr and Mn > Ba > Cr > V > Sr > Ni, respectively. High concentrations of trace elements in snow piles are a source of environmental pollution. To prevent snow storage and disposal in residential areas should be involved in future studies of environmental pollution and circular economy, so that environmental managers can reduce threats to the environment and public health, as well as initiate circular economy projects in urban areas.

Opis:
Aircraft are equipped with ice protection systems (IPS), to avoid, delay or remove ice accretion. Two widely used technologies are the thermo-pneumatic IPS and the electro-thermal IPS (ETIPS). Thermopneumatic IPS requires air extraction from the engine negatively affecting its performances. Moreover, in the context of green aviation, aircraft manufacturers are moving towards hybrid or fully electric aircraft requiring all electric on-board systems. In this work, an ETIPS has been designed and optimised to replace the nacelle pneumatic-thermal system. The aim is to minimise the power consumption while assuring limited or null ice formation and that the surface temperature remains between acceptable bounds to avoid material degradation. The design parameters were the length and heat flux of each heater. Runback ice formations and surface temperature were assessed by means of the in-house developed PoliMIce framework. The optimisation was performed using a genetic algorithm, and the constraints were handled through a linear penalty method. The optimal configuration required 33% less power with respect to the previously installed thermo-pneumatic IPS. Furthermore, engine performance is not affected in the case of the ETIPS. This energy saving resulted in an estimated reduction of specific fuel consumption of 3%, when operating the IPS in anti-icing mode.

Ice formed on radome surfaces causes communication disruption due to radio-frequency interference (RFI), which reveals the importance of de-icing systems for radomes. As a radome de-icing application, in this work, carbon nanotube (CNT) thin films were fabricated using a spray-coating method, and influence of process parameters on RF transmittance and electrothermal propertieswas investigated. With the increase of spraying time, sheet resistance of the fabricated film decreases, which results in a decrease of the RF transmittance and improvement of the heating performance. Also, the de-icing capability of the fabricated CNT film was evaluated at –20°C, and efficient removal of ice under cold conditions was demonstrated.
