FUEL TANK INERTING SYSTEM

摘要

A system for maintaining the oxygen content in the fuel vapor space of an aircraft fuel tank at less than 10 percent by volume, such system including an aspirating type mixing nozzle that draws an inert gaseous mixture from the tank vapor space and mixes it with liquid fuel being supplied to the tank whereby said inert gaseous mixture scrubs dissolved oxygen from the fuel and returns to the vapor space with the scrubbed oxygen therein. The tank includes a vent means for venting excess gasses from the vapor space to the tank exterior as the tank fills with fuel and also includes means for further scrubbing of oxygen from the fuel during climb of the aircraft and for pressurizing the tank with inert gas during descent while excluding air from the tank.
