摘要/Abstract

摘要： 时间限制性派遣（TLD）分析是飞机系统安全性分析的重要内容，其中一个重要环节是计算部件故障后的系统推力控制丧失率，目前采取较为保守的功能分析法进行分析，但其在复杂系统上的运用存在不足。为此，提出将故障树方法应用在TLD 分析中。实例证明，故障树方法可用于任意复杂系统，结果更加精确，有助于提高TLD 分析可操作性与精确度。

关键词: TLD 分析, 功能分析法, 故障树方法, 推力控制丧失率, 复杂系统

Abstract: TLD analysis is an important part of aircraft system safety analysis. One of the important links is to calculate the system LOTC rate after component failure. The current function analyzing method is cmparatively conservative, and its application in complex systems is insufficient. Therefore, the fault tree method is applied to the TLD analysis and is proved simple and accurate. It can be used in any complex system and help to improve the operability and accuracy of TLD analysis.

Key words: TLD analysis, functional analysis, fault tree method, LOTC rate, complex system
