Abstract

The invention relates to two aerospace turbofan engines. The first one is to feed rich oxygen in an intake way. The second one is to feed rich oxygen singly or synchronously in the intake way and an afterburner. Aiming at limited working height of an aviation turbofan engine, an intake way rich oxygen injecting module is arranged, a main structure of a traditional aviation turbofan engine is continuously used, and two sound cavity and separation regenerative cooling afterburners are adopted, so that the aviation turbofan engine can be changed to two aerospace turbofan engines capable of working at any height. The aerospace turbofan engine is an aerospace integral engine mainly adopting the traditional aviation turbofan engine, is excellent in technical succession, and facilitates development and application. The aerospace turbofan engine can propel an aircraft to fly at a 30-50 km height and a 3-5 M speed, or even more highly and more quickly, and is suitable for multiple aerospace integral aircrafts repeatedly used by multiple times.

Description

technical field [0001] The invention relates to two aerospace turbofan engines, belonging to an aerospace integrated engine that can fully utilize the oxygen in the atmosphere for combustion and work at any altitude. Background technique [0002] After more than 70 years of development, aviation gas turbine engines represented by aviation turbofan engines have reached a very high technical level. However, since the density of the atmosphere and the amount of oxygen decrease with increasing altitude, the thrust of such engines using air as the oxidant decreases, and the propelled aircraft cannot fly too high or too fast. Civil aviation airliners usually cruise at a speed of Mach 1 at an altitude of 10 km. Military aircraft can fly higher at supersonic speeds, but are limited in Mach number and altitude. [0003] In order to make the aircraft fly higher and faster, I proposed "two kinds of regenerative cooling afterburners with acoustic cavity and their application" (Chinese...
