摘要
经第25-143号修正案新增的第25.975条(a)(7)项要求防止燃油箱外部的火焰经由通气系统进入燃油箱而导致燃油箱爆炸的风险。通过对第25.975条(a)(7)项的修订背景、相应咨询通告AC25.975-1的研究分析,明确了燃油箱通气火焰抑制器性能标准,采用火焰抑制器作为符合手段的符合性验证思路,符合性验证关注点,为运输类飞机燃油系统的设计和符合性验证提供参考。
§25. 975 (a)(7 ) at Amendment 25 -143 requires to prevent fuel tank explosions that caused by propagation of flames from outside the tank through the fuel tank vents. Based on the review and study on the background of regulation amending and the contains in advisory circular AC25. 975 - 1, this paper definitudes the minimum standard for flame arrestor, the means of compliance for using flame arrestors as a means, and the concerns should been considered in verification. The research can provide guidance for design and verification on the fuel system for transport category airplane.
