FIELD: transport. ^ SUBSTANCE: invention relates to aircraft engineering, particularly to preparation of air fed into aircraft airtight cabins. Proposed method consists in heating a portion of air bled by compressor from atmosphere into air conditioning system in heater mounted on whatever aircraft heated element, for example jet engine. Proposed device comprises atmospheric air intake 3, solenoid-operated pneumatic valve 4, compressor 5, safety valve 18, hot line 1 accommodating heater 19 mounted on whatever aircraft heated element 20 and throttle 7 driven by temperature controller 17. Signals from temperature sensor 13 arranged in main line behind the connection of hot 1 and cold 2 lines and moisture content sensor 11 arranged in cold line accommodating throttle 8 driven by temperature controller 17 with its input receiving signal from temperature sensor 10. Moisture separator 6 is arranged behind the latter. Throttle 14 to control amount of air forced in and through the cabin 12 and controlled by temperature controller 14 whereto signals from cab temperature sensor 16 and moisture content sensor 11 are fed. ^ EFFECT: normal engine thrust, reduced fuel consumption and aircraft weight. ^ 2 cl, 1 dwg |
