摘要
基于美国联邦航空局咨询通告给出的发动机非包容转子爆破特定风险安全性评估指南,提出了一种简单易用的发动机非包容转子爆破安全性分析方法。建立了简化的转子碎片碰撞角度计算模型,以确定受转子碎片影响的系统部件;改进了失效部件组合检查单,提高分析工作效率,并确定转子碎片对系统的安全性影响。相比于传统分析方法,简化了转子爆破风险安全性分析过程,减少了分析工作量,适用于飞机系统研制初期对转子爆破风险的危害性进行保守性评估,以指导系统架构优化设计。
Based on the safety assessment guidance of uncontained engine rotor burst given in FAA advisory circular,an easy and convenient safety analysis method is proposed for engine rotor burst risk. A simplified fragment collision angle calculation model is established to check the system components affected by rotor fragment. An improved checklist for failure components is established to reduce human analysis workload and verify the rotor fragments＇ safety effect on the aircraft system. Analysis process is simplified and workload is reduced compare to traditional rotor burst risk safety analysis method. The method is applicable to preliminary stage of civil aircraft system development,used for system hazards assessment caused by engine rotor burst risk and optimizing the system architecture.
