摘要/Abstract

摘要：

航空发动机电子控制系统的时间限制派遣(TLD)分析是飞机系统安全性分析的重要内容,是商用飞机及航空发动机型号合格审定的一项必要工作,传统方法无法解决多故障情形下的TLD问题。对多故障TLD方法进行了研究,提出了多故障派遣时的派遣间隔决策方法与维修策略决策原则,基于蒙特卡罗仿真提出了多故障TLD分析方法,结合具体案例验证了方法的有效性,并针对典型全权限数字式电子控制系统(FADEC)进行了多故障TLD分析。结论表明,与单状态马尔可夫模型方法相比,本文方法具有较高的精度,误差在0.25%左右,同时能够避免马尔可夫过程繁琐的建模工作,并且具备工程实用性。

Abstract:

Time limited dispatch (TLD) analysis is an important aspect of safety analysis for airborne system, as well as a required task of type certification for commercial aircraft and aeroengines. The traditional TLD methods are not suitable for dispatch with multiple faults. TLD analysis method of dispatch with multiple faults is studied, dispatch category decision method and maintenance strategy decision principle are determined for multiple faults state, and TLD analysis method of dispatch with multiple faults is proposed based on Monte Carlo simulation; specific cases are used to illustrate the effectiveness of the method and TLD analysis of a typical full authority digital electronic control (FADEC) system is conducted in consideration of dispatch with multiple faults. Conclusions show that the proposed method herein whose error is around 0.25% has greater precision than the single fault Markov model, meanwhile, it can avoid the cumbersome work of modeling with Markov process and is practical for engineering application.

Key words: system safety, time limited dispatch, Monte Carlo simulation, Markov model, aeroengine control, airworthiness certification
