飞机发动机火警探测系统设计浅析

Analysis on Design for Aircraft Engine Fire Detection System

飞机发动机出现火警不仅严重损坏发动机,而且可能危及飞行安全。如何保证火警探测系统及时可靠工作非常重要。在介绍气动热敏式火警探测器工作机理的基础上,给出了发动机舱火警探测系统的基本设计原理。基于对系统故障模式和机理的分析,对工程上系统设计的思路策略进行了总结浅析。

The occurrence of aircraft engine fire will not only seriously damage the engine itself,but also endanger the flight safety.Thus it is very important to ensure fire detection system working timely and reliably.Based on the introduction of the working mechanism of pneumatic thermal fire detector,the basic design principle of aircraft engine fire detection system is given.Moreover,on the analysis of the system failure modes and failure mechanism,the system design strategy for engineering applications is also summarized briefly.
