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 vap...
A refueling system for a fuel tank in which the ullage gas is noncombustible and includes inert gas which is introduced into said tank from a source of such inert gas to pressurize said tank; said tank having an ullage gas outlet port and a fuel inlet port; said system comprising a fuel delivery conduit detachably connected with said fuel inlet port to refuel said tank; and means for removing oxygen dissolved in the fuel during the course of its flow through said system, and including a gas discharge opening through which the liberated oxygen is discharg...
