EFFICIENT LOW CARBON EMISSION AIRPLANE INTEGRATING JET FUEL AND CRYOGENIC FUEL SYSTEMS

摘要

A hybrid fuel airplane and methods are presented. A cryogenic fuel is transferred to an airplane propulsor from an airplane fuel system comprising a cryogenic fuel tank (302) and a jet fuel tank (310). The cryogenic fuel tank (302) conforms to an outer mold line and carries a cryogenic fuel, and is located in a portion of the airplane body while not extending beyond the outer mold line. The jet fuel tank (310) carries a jet fuel and is located in an airplane wing (306), or an airplane body, or both. A dynamic aircraft load is born on the cryogenic fuel tank, and the airplane propulsor is operated using the cryogenic fuel to generate thrust for the hybrid fuel airplane. An aerodynamic lift is generated using the airplane wing coupled to the airplane body.
