COOLED AIR SOURCE FOR CATALYTIC INERTING

An aircraft inert gas generating system includes a fuel source configured to supply fuel, a stream of reaction air (119) 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 (119) to create an air-fuel mixture, and a...

More Information
Summary:An aircraft inert gas generating system includes a fuel source configured to supply fuel, a stream of reaction air (119) 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 (119) 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 (119) includes an amount of mixing air (117) from a mixing air source, and the mixing air source includes a primary heat exchanger (108) of an aircraft ram circuit and a cooling air extraction element (128) proximate the heat exchanger (108). The mixing air can alternatively include cool air from a heat sink air source.
