AI Technical Summary
Existing aircraft systems face inefficiencies in propulsion and thermal management due to constraints on gas turbine engines, limited use of electric propulsion motors, and the need for improved cryogenic cooling solutions.
A cryogenic cooling system that generates liquid air and separates oxygen and nitrogen for on-board uses, utilizing an engine-driven system to chill engine bleed air and provide isolated sources of gaseous nitrogen and liquid oxygen for efficient cooling and propulsion.
Enhances thermodynamic efficiency by increasing oxygen availability for combustion, reduces combustion risks, and improves power density through cryogenic cooling of electric fan propulsion motors, while eliminating the need for additional inert gas systems.
