摘要:

梳理分析了美国联邦航空局为防止运输类飞机燃油箱系统发生引燃事故所发布的全部相关适航条款。基于AC25.981-1C 和AC25.981-2A 咨询通告及目前工业上对于燃油箱防爆取得的最新应用性研究成果给出了运输类飞机降低易燃性和缓解引燃源的防爆设计方法,还给出引燃源和燃油系统易燃性的验证方法。

Abstract:

All the relevant airworthiness terms published by FAA in order to prevent transporting aircraft fuel tank system explosion incidents are sorted and analyzed. Based on two advisory circulars(AC25.981-1C and AC25.981-2A) and the latest industrial application research results of current fuel tank explosion-proofs,explosion-proof design methods of flammability reduction and ignition source alleviation are given. At last,validation methods of ignition source and fuel systemflammability are introduced.

Key words: fuel tank, fuel system, airworthiness standards, fuel tank ignition prevention
