FUEL DEOXYGENATION AND FUEL TANK INERTING SYSTEM AND METHOD
First Claim
1. An aircraft fuel deoxygenation and tank inerting system, comprising:
- an inert gas source configured to supply inert gas having an oxygen concentration of less than 3%;
a fuel deoxygenation system adapted to receive fuel from a fuel source and the inert gas from the inert gas source, the fuel deoxygenation system configured to remove oxygen from the fuel and thereby generate and supply deoxygenated fuel and oxygen-rich purge gas; and
an air/fuel heat exchanger adapted to receive compressed air from a compressed air source and the deoxygenated fuel from the fuel deoxygenation system, the air/fuel heat exchanger configured to transfer heat from the compressed air to the deoxygenated fuel, to thereby supply cooled compressed air and heated deoxygenated fuel.

Abstract
An aircraft fuel deoxygenation and tank inerting system includes an inert gas source, a fuel deoxygenation system, and an air/fuel heat exchanger. The inert gas source is configured to supply inert gas having an oxygen concentration of less than 3%. The fuel deoxygenation system is adapted to receive fuel from a fuel source and the inert gas from the inert gas source. The fuel deoxygenation system is configured to remove oxygen from the fuel and thereby generate and supply deoxygenated fuel and oxygen-rich purge gas. The air/fuel heat exchanger is adapted to receive compressed air from a compressed air source and the deoxygenated fuel from the fuel deoxygenation system. The air/fuel heat exchanger is configured to transfer heat from the compressed air to the deoxygenated fuel, to thereby supply cooled compressed air and heated deoxygenated fuel.

15. A fuel deoxygenation system comprises:
-
a housing having a fuel inlet, a fuel outlet, a gas inlet, and a gas outlet, the fuel inlet adapted to receive fuel from a fuel source, the gas inlet adapted to receive inert gas from an inert gas source; and a disk rotationally mounted in the housing and coupled to receive a drive torque, the disk configured, upon receipt of the drive torque, to rotate and thereby produce a thin film of fuel thereon and propel fuel radially outward toward an outer perimeter of the disk. - View Dependent Claims (16, 17, 18, 19, 20)
