Throughout the world, the reliability-based approach to safety design of aircraft systems is quite mature and widely used. However, there are still shortcomings in the reliability-based aircraft system safety analysis method. It cannot dynamically analyze the accident evolution process and lack consideration of the complex situation of multifactor coupling. On the basis of the original aircraft system safety analysis method, this paper innovatively proposes a functional hazard analysis (FHA) method based on the analytic hierarchy process (AHP) and multifactor fuzzy comprehensive assessment (FCA). The purpose is to improve the objectivity and quantification of the FHA method in the safety design of aircraft systems. At the same time, in the terminal airworthiness verification, this paper proposes a repeatable and controllable virtual test flight verification method, which aims to reduce the cost and cycle of the terminal airworthiness verification and expand the coverage of the envelope verification. Finally, combined with the clauses in MIL-HDBK-516B, a case calculation is carried out to verify the feasibility of the proposed method.
在全球范围内，基于可靠性的飞机系统安全设计方法已经相当成熟并得到广泛应用。然而，基于可靠性的飞机系统安全分析方法仍然存在一些缺陷，无法动态分析事故演化过程，并且缺乏对多因素耦合复杂情况的考虑。在原始飞机系统安全分析方法的基础上，本文创新性地提出了一种基于层次分析法（AHP）和多因素模糊综合评估（FCA）的功能危险分析（FHA）方法，旨在提高飞机系统安全设计中 FHA 方法的客观性和量化程度。同时，在终端适航验证中，本文提出了一种可重复和可控的虚拟试飞验证方法，旨在降低终端适航验证的成本和周期，并扩大包线验证的覆盖范围。最后，结合 MIL-HDBK-516B 中的条款，进行了案例计算，验证了所提出方法的可行性。
