FIELD: engines and pumps. ^ SUBSTANCE: pylon includes front and rear bodies of aerofoil section. Pylon bodies are tubular. Pylon includes at least two tubes located one after the other with rounded front edge. One end of tube is fixed on combustion chamber wall through the support, and free ends of tubes are plugged. Tubes are inclined to axis of chamber at sweep angle. Pylon also includes fuel supply system to combustion chamber. Air and fuel is supplied to combustion chamber during the start. At subsonic and supersonic air flow velocities the temperature of the air coming onto the pylon increases over self-ignition temperature of fuel-air medium. It leads to fuel-air mixture ignition. ^ EFFECT: simpler pylon design, providing fuel supply, mixture formation, ignition and combustion of fuel-air mixture throughout the front of combustion chamber in cruising mode of engine operation. ^ 2 cl, 2 dwg |
