AERO-ENGINE USING LIQUID AIR AS THERMAL WORKING MEDIUM

WIPO Patent Application WO/2024/045289

A1

The present invention relates to an aero-engine using liquid air as a thermal working medium. The aero-engine is technically characterized in that liquid air is used as a thermal working medium, and the liquid air absorbs heat to be vaporized from high-heat compressed air generated by a turbine-type normal-temperature air compressor, so as to push a turbine-type high-pressure steam turbine to work; the turbine-type normal-temperature air compressor, a turbine-type low-temperature air compressor and a propeller are driven to operate at the same time; meanwhile, the low-temperature cooling capacity carried by the liquid air is repeatedly utilized by using an opposite forced convection heat transfer composite pipe, so as to efficiently generate a recoil thrust to push an aerospace plane to lift off and take off; and during normal quick navigation, collected relative motion air kinetic energy is used to replace the turbine-type high-pressure steam turbine to work, and liquid air and electric energy are continuously and quantitatively produced.
