基于FAA适航要求的飞机燃油箱防爆技术研究

摘要

燃油箱爆炸是航空安全的主要威胁之一。通过研究FAA对于燃油箱防爆适航条款的要求，分析了燃油箱内可能出现的点火源分类和防止出现点火源的方法以及降低燃油箱可燃性的方法。针对FAA推荐的燃油箱防爆最重要的方法之一的惰化系统进行描述，重点阐述了惰化系统的构架和原理，并对惰化系统各子系统的功能进行了论述。%The fuel tank explosion is one of main aviation safety threats. The paper analyses the kinds of ignition sources which may appear in fuel tank , by researching the ignition prevention requirement of FAA. Also, the paper researches the method of ignition sources prevention and reduction flammability. As FAA recommending one of the most important methods of fuel tank flammability reduction, the paper describes the inerting system. The inerting system configuration and theory have been described with emphasis. And the functions of subsystems of inerting system have been described.
