Aircraft Fuel Tank And Inerting System Therefor

摘要

An inerting system for an aircraft fuel tank ( 10 ) uses an air separation device ( 12 ) to produce a supply of nitrogen-enriched air to replenish the fuel tank on consumption of fuel and to maintain the pressure difference across the walls of the tank ( 10 ) below design limits. The air separation device ( 12 ) provides substantially the whole of the mass of the gas required and so there is substantially no inward venting. This provides a substantially homogenous nitrogen content in the air in the tank ( 10 ).
