    Opis:
    The effect of aircraft emissions on the global climate is a serious long-term environmental issue faced by the aviation industry. As the number of passengers grows, so does the use of jet fuel and the emission of greenhouse gases (GHG). This may destabilize the world’s climatic systems, which will consequently lead to global, regional and local environmental, economic and social damage. The Intergovernmental Panel on Climate Change (IPCC) estimates that aircrafts are currently responsible for 3.5 % of the total anthropogenic greenhouse effect. To avoid the negative consequences of climate change, it is necessary to fully understand factors affecting this problem locally and develop methods of mitigating airport climate effects. This article describes and analyses calculations of radiative forcing of aircraft emissions and the radiative impact of clouds in the surrounding area of the Lviv airport. The calculated values were verified against temperature data for the city and at the airport provided by meteorological authorities.

    Opis:
    In the last two decades, there has been observed a noticeable increase in the popularity and availability of air transport services, including regional ones. This intensive development of transport is accompanied by an increase in the adverse impact to the environment, increases noise level, and exhausts emissions, despite the modification and modernization of engines. Determining the emission for regional flights takes into account the specificity of the aircrafts design, such as the size of the aircraft and the performance of the engines. In this article, an attempt was made to determine the CO2 emissions of a business jet flying from Gdansk to Rzeszow. The methodology of the research (the method of calculating emissions based on fuel consumption) and the performance characteristics of the aircraft engines have been described. In the first part of the article, the speed-altitude characteristics of the DGEN-380 engine for different cruise parameters were determined using the virtual engine test bench WESTT CS/B. These characteristics have enabled the engine to match the flight characteristics (altitude, speed). For specific flight parameters, the thrust and fuel consumption were determined. On this basis, for the adopted trajectory and flight time of an aircraft equipped with two DGEN-380 engines, total fuel consumption and CO2 emission factors and values in CRUISE phase was determined with regard to the wind speed and direction. The obtained results were illustrated graphically and discussed.

    Opis:
    An airport authority needs accurate information about the actual amount of harmful emissions being generated within its airspace, to be able to take measures leading to their reduction. This article presents two methods for estimating the amount of these emissions from aircraft engines during the take off and landing cycle (LTO) in the airspace of a medium-sized airport: one based on the total amount of the aircraft annually operated in it, and a second, more precise, one for a specific airline annually operating at this airport. The conclusions stemming from the comparison of these methods can support the introduction of operational and technical procedures reducing harmful emissions in the airport airspace during LTO cycle.

    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:
    Multi-role aircraft as a technical object of a certain functional purpose and operating characteristics resulting from its construction, affects the operating environment mechanically, as a source of disturbance of the medium in which it moves and chemically, by generating the emission of harmful substances resulting from the need to use consumable fuels. Operation of multi-role aircraft, in contrast to civil aircraft, is characterized by high volatility of flight data resulting from the diversity of performed tasks. Therefore it seems desirable to attempt the ecological evaluation of the drive in terms of emissions on the basis of a dedicated test for a particular group of aircraft. An attempt at such an assessment is presented in this article.
