Abstract. Aircraft flight is the main operation of any airline. To ensure competitiveness and good economical indices the flight time should be considerably longer than the total time an airplane spends on the ground. Aircraft flight is provided by a power plant, which is based on heat engines – heat machines that convert heat energy into effective mechanical work. The heat additive to the operating fluid in such engines nearly always occurs by means of hydrocarbon fuel (kerosene or aviation gasoline) combustion. While burning, the combustion products are released, some of which cause significant harm to the environment. Increasing environmental friendliness is an actual task today, and non-compliance of engines with ICAO standards on hazardous emissions limits the domestic aircraft sales and exploitation abroad. In this regard, the search for ways to improve the environmental performance of aircraft engines is a priority for the aviation industry.

Key words: combustion chamber, aviation gas-turbine engine, emissions of harmful substances, environmental friendliness.
