ABSTRACT:
Refueling equipment for aircraft fuel tanks of the type which are pressurized during flight of the aircraft by an airborne source of inert gas such as nitrogen to maintain the ullage gases noncombustible characterized in that the fuel during the course of its flow through said refueling equipment is deoxygenated before it reaches the aircraft fuel tank with the oxygen liberated from the fuel being discharged from the refueling equipment. The fuel passing through the refueling equipment is deoxygenated by scrubbing with noncombustible ullage gas (fuel vapor, inert gas, and oxygen insufficient to support combustion) from the aircraft fuel tank or by scrubbing with inert gas such as nitrogen carried by said equipment via control means operative to minimize the inert gas flow according to the fuel flow rate through the equipment into the aircraft fuel tank, or by subjecting the fuel to partial vacuum while the fuel is agitated thus to liberate oxygen therefrom and to discharge the same from the refueling equipment.
