ABSTRACT:
A heat exchange system for a supersonic flight vehicle. A first conduit connects the gas (e.g., helium) exit of a compressor of a gas-driven turbocompressor to the gas inlet of a turbine of the turbocompressor, and a second conduit connects the gas outlet to the turbine to the gas entrance of the compressor. The first conduit has a portion positioned near a hotter temperature region (e.g., the combustor wall) and the second conduit has a portion positioned near a colder temperature region (e.g., the fuel region) of the flight vehicle. The temperature difference self powers the turbocompressor which can transfer large amounts of heat and which is hermetically-sealed in a housing against gas leaks.
