ABSTRACT:
A fuel system for horizontal takeoff and hypersonic aerospace vehicles. The fuel vapor generated in the fuel tank is mixed with the liquid fuel from the tank. The mix is compressed and supplied to the engine system as usable fuel. The compressor used for compressing the combination gas and liquid can be driven from a turbo expansion cycle using aerodynamic heating of the vehicle. Several different embodiments for mixing the fuel vapor with liquid fuel are disclosed.
