FIELD: aeronautical engineering; air-conditioning systems for flying vehicles equipped with double-flow TURBOJET engines. SUBSTANCE: system contains air-to-air heat exchanger whose hot line is connected with engine compressor by means of air bleeding main and is brought in communication with flying vehicle cabin. Blow line of heat exchanger is connected with fan loop of engine by means of air duct and is brought in communication with atmosphere. Damper of flow and temperature regulator is fitted in air duct before blow line of air-to-air heat exchanger. Flow laminarizer made in the form of holes over air duct contour is mounted in air duct before damper of flow and temperature regulator. Axes of holes may be made at an angle relative to longitudinal axis of air duct in way of flow. Holes are made in one transversal plane of air duct and are located in several rows at angular shift. EFFECT: higher efficiency. 5 cl, 5 dwg
