FIELD: engine manufacture. SUBSTANCE: engine has adjustable diffuser, compressor, combustion chamber, compressor drive, and reaction nozzle. Adjustable diffuser and compressor are common for all engines incorporated in unit. The latter also has adjustable compressor drive, subsonic nozzle of air-feed jet engine, supersonic air-feed jet engine with its separate combustion chamber, pipeline running from common compressor for feeding compressed air to it, and supersonic non-adjustable nozzle. Pressurized shell inside fuselage is placed around compressor and its drive. Air duct provides communication between shell and diffuser. One or more supersonic air-feed jet engines are used depending on quality of drive and its power capacity; each of them is hinged in position. Compressed-air pipeline running to combustion chamber of each air-feed jet engine incorporates flexible members. EFFECT: enlarged functional capabilities of air-feed jet engine unit. 3 cl, 4 dwg
