Abstract
The invention discloses a stamping-turbine air injection composite aero-engine and aims to solve the problems that the existing gas turbine engine is complicated in structure and limited in running speed range, and a ramjet engine cannot voluntarily start, cannot run at a low speed, is difficult in cooling, and has higher requirements for the high temperature resistance of a complete machine. The stamping-turbine air injection composite aero-engine comprises a stamping air inflow cone, an outer duct engine case, an inlet guide blade, a liquid oxygen regulating valve, a liquid nitrogen regulating valve, an inner duct engine case, a rectifying blade, a fuel oil regulating valve, a centrifugal compressor, a diffuser, a combustor, a concentric shaft, a worm wheel, an inner duct rectifying nozzle, a starting dynamo and the like. The stamping-turbine air injection composite aero-engine effectively utilizes the stamping effect and advantages of a turbojet engine, participates in precooling treatment, effectively solves the problems that the ramjet engine takes air in the starting and high-speed states, and the engine power is limited, is simple in structure, low in cost, high in efficiency, wide in running speed range and low in running speed of the complete machine, and has a better application prospect.
Description
technical field [0001] The invention relates to the field of aviation, in particular to the field of aero-engines, in particular to a ramjet-turbojet compound aero-engine. As a low-cost ram-turbojet compound aeroengine, the invention has good application prospects. Background technique [0002] As an engine that provides the power required for flight by an aircraft, an aeroengine is a highly complex and sophisticated thermodynamic mechanism. As the heart of an aircraft, an aero engine is known as the "flower of industry". It directly affects the performance, reliability and economy of an aircraft, and is an important manifestation of a country's technological, industrial and national defense strength. Due to the high technical threshold of aero-engines, only a few countries in the world, such as the United States, Russia, the United Kingdom, and France, can independently develop high-performance aero-engines. [0003] According to different operating mechanisms, aeroengine...
