A comprehensive assessment of the impact of aircraft emissions has concluded that these emissions are small in comparison to other man-made emissions but could have a significant effect on atmospheric chemistry and cloud cover, with possible implications for the ozone layer and climate. The review was carried out by leading European researchers, under the auspices of the EU's Environment and Climate research programme, and the results have just been published in the scientific journal "Atmospheric Environment".
The findings of the review rely heavily on the results of European and national research projects, such as AERONOX, POLINAT, MOZAIC, AEROCHEM, AEROCONTRAIL, and LOWNOX projects supported by the Environment and Climate programme and the Industrial and Materials Technologies (BRITE-EURAM) programme, as well as national projects.
The authors conclude that, firstly, the warming (climate) effect associated with the ozone increase from NOx emissions is comparable to the warming effect of CO2 emitted by aircraft, secondly, the warming effect of the changes in cloudiness through contrail formation appears also to be of the same magnitude as the warming effect of CO2, and thirdly, the development of a fleet of supersonic aircraft flying at high altitudes could perturb the ozone layer in the stratosphere.
A number of gaps in existing knowledge have been revealed in the review, in particular the lack of understanding of the region where aircraft fly, which straddles the boundary between troposphere and stratosphere. In additio

In addition, the need for study of the effect of aircraft emissions on the abundance of particles providing the surface for complex heterogeneous reactions was also highlighted. Work is continuing on these issues through the Environment and Climate programme and the Coordination of Research for the Study of Aircraft impact on the Environment (CORSAIRE) initiative. Research will continue under the upcoming Fifth RTD Framework Programme, in particular, under the Key Actions on "Global change, climate and biodiversity" and "New perspectives in aeronautics".
At international level, European scientists will also continue to participate in the "Aviation and Global Atmosphere" report, currently being carried out by the Intergovernmental Panel on Climate Change (IPCC).

With the growth of air transportation on airplanes of the transport category, their negative impact on the environment and humans increases. The environmental impact of civil aviation began to be addressed in the early 70s of the 20th century. There are three critical areas of impact: the surface layer of the atmosphere, where aerodrome emission is important, the upper troposphere at an altitude of about 10 km, where cruise flights of civilian aircraft take place, and not so long ago, the lower stratosphere (10…22 km), where, as expected, must be cruising the flight of supersonic transport of the future. In the first zone, the effect is direct damage to human health. In the second, aviation affects climate change. In the third zone, the ozone layer may be depleted as a result of aviation exposure. ICAO has established strict restrictions on all types of harmful effects, which are stipulated in our country in AP-25 and AP-36. It is noted that these requirements are constantly being tightened, as a result of which the noise level of the world fleet of aircraft over the past half-century has decreased by more than 30 percent. The article discusses the scheme of creating an aircraft taking into account environmental restrictions and economic costs to the level of decision-making on these problematic issues. The implementation of this approach in domestic aircraft construction is the creation of its modification, the An-132D, based on the An-32B aircraft. With an increase in the c

PROBLEMS OF CREATION OF AIRCRAFT CATEGORY PLANES ACCORDING TO ENVIRONMENTAL LIMITATIONS A. Los, V. Ryabkov, T. Sereda With the growth of air transportation on airplanes of the transport category, their negative impact on the envi- ronment and humans increases. The environmental impact of civil aviati on began to be addressed in the early 70s of the 20th century.
There are three critical areas of impact: the surface layer of the atmosphere, where aerodrome emission is important, the upper troposphere at an altitude of about 10 km, where cruise flights o f civilian aircraft take place, and not so long ago, the lower stratosphere (10 …22 km), where, as expected, must be cruising the flight of supersonic transport of Проектування літальних апаратів 11 the future. In the first zone, the effect is direct damage to human health. In the second, av iation affects climate change. In the third zone, the ozone layer may be depleted as a result of aviation exposure.
With an increase in the carrying capacity and range of this modification by re-arranging the wing -tail + tail assembly system of bearing surfaces, as well as replacing the power plant, it was possible to significantly reduce the fuel efficien cy of this modification to 222 g / t km, which is the highest indicator for light vehicles airplanes. This means that An -132D has the least impact on greenhouse gas emissions and emis- sions.
Besides, An-132D has several other advantages: - variable revolutions of the propeller Nвв = 850 … 1200 rpm; - “silent taxiing” at Nвв = 850 rpm within the aerodrome; - emergency operation of the main engine in case of failure of one of the two, not only during take -off but also, if necessary, on the route; - significantly better environmental indicators for harmful emissions of the marching engine and noise on the ground. An-132D is an implemented example of creating a transport category aircraft taking into account environmen- tal restrictions. Keywords: aircraft of the t ransport category; noise; harmful emissions; environmental impact; design re- strictions.
