FIELD: air and space equipment. ^ SUBSTANCE: proposed method of operation of air-space jet power plant comes to dynamic compression of air flow in intake device, afterpressing it by compressor set into operation by engine, delivery of compressed air into combustion chamber, turbulization with supply of heat to compressed air and expansion of combustion products in jet nozzle. Air flow from intake device is divided into three flows passing along three circuits formed by hollow three-step axle, being carrying structure, and operating as independent engines and in set. Air flows of first and second circuits are compressed by low and high pressure compressors successively and in parallel, which are set into rotation by synchronous electrical machines. Number of revolutions of synchronous machines is regulated by frequency of supplied voltage, their movable parts creating excitation are made in form of permanent magnets and are combined with rotors of compressors. Fixed parts are current-carrying ones and are made in form of field forming highlyconductive windings supplied by voltage. Dynamic compressor of third air flow is created in third circuit, said air flow supplies magnetogas dynamic system consisting of plasma accelerator and electric generator. Then all three gas flows are supplied to combustion chamber and replenishment of energy stroke is provided. ^ EFFECT: increased efficiency of plant, improved ecological parameters and thrust characteristics at takeoff, flight, braking and returning of plant into dense layers of atmosphere. ^ 11 cl, 1 dwg |
