民用飞机火灾特定风险分析方法研究

Specific risk analysis method for civil aircraft fires

民用飞机的防火设计是飞机的一个重点研究方向。火灾是经常发生的一类航空事故,无法建立相应的风险模型定量评估其发生后对相关区域系统和结构的危害。基于美国联邦航空局咨询通告给出的可燃液体的防火安全性分析指南,提出了一种简单易用的火灾特定风险分析方法。建立了火灾特定风险分析流程,介绍了防火区域划分原则和火灾特定风险分析思路,最后以某大型民用飞机机型为例,进一步说明火灾特定风险分析方法的应用,适用于民用飞机全机防火正向设计。

In the actual design of civil aircraft,fire protection design is a key research direction for aircraft.Fire is a frequent type of aviation accident,and it is not possible to establish a corresponding risk model to quantitatively assess the hazards to the systems and structures in the relevant zone after its occurrence.This paper proposes a simple and easy-to-use fire specific risk analysis method based on the guidelines for fire safety analysis of flammable liquids given in the FAA Advisory Circular.The fire specific risk analysis process was established,the principle of fire protection zones division and the idea of fire specific risk analysis were introduced,and finally a civil aircraft model was used as an example to further illustrate the application of the fire-specific risk analysis method,which is suitable for the positive design of civil aircraft fire safety.
