FIELD: manufacture of engines, aviation, cosmonautics, automotive industry, shipbuilding, new flying vehicles. SUBSTANCE: engine includes two TURBOJET engines located at angle relative to outer loop which operate simultaneously or in turn together with outer loop. Each TURBOJET engine includes turbo-compressors which are supplied with hydrogen and oxygen fed from electrolyzers; hydrogen and oxygen are mixed in ignition chamber where they are ignited by laser beam; engine contains also turbine, combustion chamber from which gas jet of flame passes to turbines of outer loop consisting of atmospheric air supply system, thermal heating system, turbines, turbogenerators for generation of electric power required for operation of laser, electrolyzer and on-board equipment. Outer loop is provided with steam condensers for reuse of water as propellant and separation of steam to obtain dry gas used jet entering the combustion chamber and nozzle which consists of many nozzles with flaps. EFFECT: enhanced efficiency. 1 dwg
