Method and device for inerting an aircraft fuel tank

摘要

Air enriched with an inert gas is produced from a compressed air source (9) inside the aircraft and is admitted into the tank (12). During the aircraft cruise phase a first fraction of air having a first inert gas content is produced and admitted into the tank at a first flow rate. During the descent phase a second fraction of enriched air, having a second inert gas content less than the first, is produced and admitted into the tank at a second higher flow rate. An Independent claim is included for a fuel tank inerting system
