Title:
SYSTEM AND METHOD FOR COOLING AND GENERATING POWER ON HIGH SPEED FLIGHT VEHICLES
Document Type and Number:
Japanese Patent JP2021020668
Kind Code:
A
Abstract:
To provide a method and an apparatus for cooling a surface on a flight vehicle and/or generating power.SOLUTION: Supercritical working fluid is circulated through a fluid loop that includes the steps of: compressing the supercritical working fluid by a compressor, heating the supercritical working fluid by a heat absorbing portion that is thermally coupled to a surface; expanding the supercritical working fluid in a thermal engine to generate work output; cooling the supercritical working fluid; and recirculating the supercritical working fluid to the compressor. The work output of the thermal engine is operably coupled to the compressor, and may optionally be coupled to a generator in order to generate power. The supercritical working fluid absorbs heat from the surface, eliminates hot spots and permits use of lighter and/or less expensive material.SELECTED DRAWING: None
