轮胎爆破下飞机液压能源系统安全性分析方法

摘要

为了评估飞机在发生轮胎爆破时对液压系统的影响，提出一种分析轮胎爆破下飞机液压系统安全性的方法。轮胎爆破会损坏液压管路，直接影响到液压能源系统及下游设备的正常工作，对飞机的飞行安全造成重大影响。分析方法基于轮胎爆破模型假设，首先分析轮胎爆破冲击波对液压系统的影响，随后综合考虑碎片的影响，对起落架舱进行轮胎爆破影响范围的空间扫略分析，得到轮胎爆破对液压能源系统的安全性影响。本安全性分析方法也可作为其他系统专业轮胎爆破安全性分析以及整机级安全性分析的输入。%A method was proposed in aim of aircraft hydraulic system safety analysis for tire burst. Tire burst would destroy the hydraulic system tube in the landing gear bay, directly affects the normal operating of hydraulic system and the downstream users, is a big threat to aircraft safety lfight. This method base on the tire burst model hypothesis, ifrstly analyzed the shock wave’s inlfuence to the hydraulic system, and then combined the inlfuence of the debris, to perform a tire burst’s incidence sweep analysis for the landing gear bay, ifnally to obtain the conclusion of tire burst safety inlfuence on hydraulic system. This method can be the tire burst analytical input of other system and the aircraft level safety analysis.
