本文通过分析民用飞机复杂系统的适航要求以及符合性验证方法,针对复杂系统适航安全性评估中建立故障树困难的问题,提出利用动态逻辑门建立动态故障树并模块的方法,并研究了动态子树的分析方法。最后以燃油系统为案例,分析燃油了系统的适航要求,提出燃油系统适航安全性评估的基本流程。
In this paper, by analyzing the requirements of airworthiness and compliance verification of complex aircraft civil systems, aiming at the difficulty of establishing fault tree in airworthiness safety assessment of complex systems, a method of establishing dynamic fault tree and module using dynamic logic gates is proposed. Dynamic sub-tree analysis. Finally, taking the fuel system as an example, the paper analyzed the airworthiness requirements of the fuel system and proposed the basic process of the airworthiness safety assessment of the fuel system.
