Aircraft engine fuel system

This invention describes a fuel system for aircraft that uses liquid hydrogen. It takes super-cold liquid hydrogen from a tank, heats it to turn it into a gas, and then pumps this gaseous fuel to the engine. The system is designed to deliver the hydrogen fuel at the precise temperature needed for either a gas turbine engine or a hydrogen fuel cell.

Why it matters: Since 2023, the fundamental challenges of safely and efficiently integrating cryogenic hydrogen fuel systems into aircraft remain significant. While interest in hydrogen aviation is growing, the specialized components and stringent regulatory requirements still present substantial hurdles.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCryogenic hydrogen, specialized vaporizer, pump, heater, aircraft.
