Air-breathing rocket engines and hypersonic aircraft

Abstract

The invention discloses an air-breathing rocket motor and a hypersonic speed plane. The air-breathing rocket motor and the hypersonic speed plane include an air inlet, a heat exchanger, a gas compressor, a main combustion chamber and an exhaust nozzle, and the air inlet, the heat exchanger, the gas compressor, the main combustion chamber and the exhaust nozzle are arranged in sequence. The gas compressor is provided with a turbine, and the turbine provides driving force for the gas compressor. A wall surface cooling channel is arranged on the outer wall surface of the main combustion chamber and the exhaust nozzle. The air-breathing rocket motor and the hypersonic speed plane also include an oxidizing agent pump, a fuel pump, a pre-burning chamber and an injector. The oxidizing agent pumpcommunicates with the heat exchanger so that oxidizing agent enters the heat exchanger to cool air which enters the air inlet. The fuel pump communicates with the wall surface cooling channel, so thatfuel enters the he wall surface cooling channel to cool the exhaust nozzle and the main combustion chamber. The oxidizing agent after cooling the air and the fuel after cooling the exhaust nozzle andthe main combustion chamber correspondingly enter the pre-burning chamber for combustion to generate rich combustion gas in the pre-burning chamber. The injector is used for spraying the air cooled by a heat exchanger and pressurized by a gas compressor into the main combustion chamber for mixed combustion, as well as the rich combustion gas after driving the turbine.

Description

technical field [0001] The invention relates to the field of aeroengines, in particular to an air-breathing rocket engine. In addition, the present invention also relates to a hypersonic aircraft comprising the above-mentioned air-breathing rocket engine. Background technique [0002] At present, there are two main types of engines used in the aviation field: piston engines and gas turbine engines. The application of piston internal combustion engine in aircraft has created a new era of human flight. The emergence of gas turbine engines has enabled humans to achieve supersonic flight. With the advent of the era of hypersonic flight, gas turbine engines are facing insurmountable technical difficulties, and will be subverted by new engine technologies. [0003] In the future, hypersonic aircraft must not only be able to take off and land horizontally, but also be able to cruise at hypersonic speeds. Its power system must have the ability to work in a wide range of Mach numb...
