Abstract:
An aerospace turbofan engine that injects oxygen-enriched gas from an inlet includes an oxygen-enriched gas injection component, a body structure, an afterburner middle portion and a first afterburner outer ring. An aerospace turbofan engine that injects oxygen-enriched gas from an inlet and an afterburner individually or simultaneously includes an oxygen-enriched gas injection component, a body structure, an afterburner middle portion and a second afterburner outer ring. The aerospace turbofan engines which fully utilize oxygen in the atmosphere for combustion and work in various flight altitude ranges adopt regenerative cooling-type afterburners with acoustic cavity and baffle plates, so that an aircraft can fly to an altitude of 20-50 km and reach a speed of Mach 2-5. Variants of the aerospace turbofan engines are disclosed.

Claim (Index 6):
The aerospace turbofan engine of  claim 2 , wherein\n a plurality of fanned straight flutes having the same width and arc length as one another are formed on the acoustic cavity and uniformly distributed along the circumference of the acoustic cavity; a plurality of acoustic cavity ribs are arranged between the plurality of fanned straight flutes without regenerative cooling; the plurality of fanned straight flutes include a plurality of deep acoustic cavities and a plurality of shallow acoustic cavities which are in a alternate arrangement with an alternating ratio of 2:1, 1:1 or 1:2; and a plurality of screw pile holes are formed in metal solid portions of the plurality of shallow acoustic cavities.
