Abstract

The invention provides an axisymmetric full-speed-domain ramjet engine using electric auxiliary supercharging, and belongs to the technical field of aerospace equipment. The problem that a traditional hybrid engine cannot meet the high-speed requirement of an aircraft is solved. The engine comprises an air inlet channel center cone, an engine shell, a fixed guide column, a high-speed motor, an air compressor, a fuel nozzle, a combustion stabilizer and a spray pipe, the air inlet channel center cone is arranged in the front end of the engine shell through the fixed guide column, the high-speed motor is arranged in the air inlet channel center cone, and the air compressor is connected with the high-speed motor; a combustion chamber is arranged in the portion, at the rear end of the gas compressor, of the engine shell, the multiple fuel nozzles are evenly distributed on the inner wall of the engine shell in the circumferential direction of an inlet of the combustion chamber, and the multiple combustion stabilizers are evenly distributed in the area, close to the center, of the combustion chamber in the circumferential direction of the inlet of the combustion chamber. The rear end of the engine shell is connected with the nozzle. The method is mainly used for the full-speed-range ramjet engine.

Description

technical field [0001] The invention belongs to the technical field of aerospace equipment, in particular to an axisymmetric full-speed range ramjet engine using electric auxiliary boosting. Background technique [0002] Aerospace vehicles with horizontal take-off and landing capabilities are an important development direction in the future aerospace field, and one of the key technologies for aerospace vehicles with horizontal take-off and landing capabilities is a wide-speed engine that can achieve Ma0-6+ flight. The main problem faced by the current wide-range engine scheme is that the dual-mode ramjet engine suitable for hypersonic flight cannot operate at a low Mach number, so most of the wide-range engines use combined power, with rocket engines, turbine engines and The combination of the three power modes of the ramjet engine is mainly combined. The rocket ramjet combined with the rocket and the ramjet has a small specific impulse and weak load capacity at low Mach nu...
