FIELD: engines and pumps.SUBSTANCE: hypersonic propulsive jet engine includes an air intake with a central body, a combustion chamber, a fuel injector connected by means of pylons to the air intake, and a control system. The fuel injector is installed in a central body of the air intake and made in the form of a gas jet resonator with a sharp front edge. The inlet of the gas jet resonator is aligned with a nose part of the central body and faces an incoming air flow, and its inner cavity is connected to the fuel system. The rear wall and some part of side wall of the gas jet resonator are porous and have controlled porosity. On the outer side of the rear wall of the gas jet resonator there arranged is a flat igniter with holes, which is electrically connected to an engine control system and a pulsating electric field source. Through the fuel injector before the air intake there supplied is nanodisperse fuel containing carbon nanotubes with hydrogen encapsulated in them in two flows: through the gas jet resonator inlet towards the incoming air flow and through its porous walls. A pulsating electric discharge with frequency in the range of 0.1 to 25 kHz is created between the igniter on the rear wall of the gas jet resonator and the combustion chamber.EFFECT: improving fuel-and-air mixture preparation and combustion processes; improving fuel complete combustion and fuel efficiency of an engine; improving its mass and dimensional characteristics.2 cl, 1 dwg |
