Abstract: A catalytic oxidation system for generating inert gas includes a catalytic oxidation unit, which includes a catalyst oriented between an inlet and an outlet of the catalytic oxidation system, a first temperature sensor in operable communication with the catalyst, and a second temperature sensor in operable communication with the catalyst. The first temperature sensor is nearer to the inlet than the second temperature sensor and the second temperature sensor is nearer to the outlet than the first temperature sensor.

Abstract: An aircraft inert gas generating system includes a fuel source configured to supply fuel, a stream of reaction air having a first temperature, an air-fuel mixing unit configured to receive an amount of the fuel and an amount of the reaction air stream to create an air-fuel mixture, and a catalytic oxidation unit configured to receive and react the air-fuel mixture. The stream of reaction air includes an amount of mixing air from a mixing air source, and the mixing air source includes a primary heat exchanger of an aircraft ram circuit and a cooling air extraction element proximate the heat exchanger. The mixing air can alternatively include cool air from a heat sink air source.

Abstract: Systems and methods for generating oxygen-depleted fluid are described. The systems include a compressor, a motor operably coupled to the compressor by a shaft and configured to rotationally drive the compressor through the shaft, and an air separation module configured to receive a supply air as an input and generate oxygen-rich fluid and oxygen-depleted fluid as an output. The oxygen-depleted fluid is directed to the motor to provide cooling thereto.

Abstract: An air separation module includes a separator, a canister, and a nominal-length end cap. The separator is arranged to separate ambient air into an oxygen-enriched air fraction and a nitrogen-enriched air fraction. The canister supports the separator and has a canister end flange, a canister intermediate flange and a canister end, the canister intermediate flange arranged between the canister end flange and the canister end. The nominal-length end cap is fixed to the canister end flange, and the separator extends between the canister end flange and the canister end. Nitrogen generation systems and methods of generating nitrogen-enriched air flows are also described.
