摘要:
A cryogenic fuel storage system for an aircraft is disclosed including a cryogenic fuel tank having a first wall forming a storage volume capable of storing a cryogenic liquid fuel; an inflow system capable of flowing the cryogenic liquid fuel into the storage volume; an outflow system adapted to deliver the cryogenic liquid fuel from the cryogenic fuel storage system; and a vent system capable of removing at least a portion of a gaseous fuel formed from the cryogenic liquid fuel in the storage volume.
摘要:
An aircraft system comprising a fuel storage system comprising a first fuel tank capable of storing a first fuel and a second fuel tank capable of storing a second fuel is disclosed herein. The aircraft system further comprises a fuel cell system comprising a fuel cell capable of producing electrical power using at least one of the first fuel or the second fuel, and a fuel delivery system capable of delivering a fuel from the fuel storage system to the fuel cell system.
摘要:
A butterfly valve for a gas turbine engine includes a valve shaft and a valve disk. The valve disk has a centerline axis that extends through the valve disk. The valve disk also includes a shaft opening, an outer periphery, an outer surface, a first side, and a second side. The first side is opposite the second side. The shaft opening extends through the valve disk adjacent the centerline axis, and is sized to receive the valve shaft therein. The disk outer surface extends over the first and second sides, and is tapered between the outer periphery and the centerline axis over at least one of the disk first and second sides.
摘要:
Disclosed here are integrated methods and systems for producing fuel from biomass. The methods and systems pertain to gasifying a feed derived from biomass fermentate separation residue, such as corn-based distiller's grains, and producing a liquid transportation fuel component, such as aviation turbine fuel, from the gasified feed in a hydrocarbon synthesis reactor. At least a portion of the waste heat from the hydrocarbon synthesis reactor is supplied to a thermal process for liquefying, fermenting or distilling a biomass, or to a thermal process for separating or treating a biomass fermentate separation residue.
摘要:
A gas turbine engine includes a compressor including a casing and a stator assembly. The casing extends around the stator assembly, the stator assembly including a plurality of stator vanes, and a plurality of bleed scoops. Adjacent stator vanes define a static high-pressure region, the bleed scoops formed at least partially within the high pressure region.
