摘要
民用飞机在巡航时发生后压力框破裂(APBR),瞬间产生的冲击波可能破坏后机身关键结构与系统,影响继续安全飞行和着陆。将APBR视为空气介质压力容器的爆炸,讨论了APBR冲击影响的工程计算方法,提出了APBR风险分析方法和风险减缓的设计措施,为飞机系统安全性设计及其适航符合性验证提供理论支持。
When the Aft Pressure Bulkhead Rupture （APBR） occurred during the cruise phase of civil aircraft, the shock wave generated instantaneously may destroy the critical structure and systems of the aft fuselage, which may affect continued safe flight and landing. This paper treated the APBR as the explosion of air pressurized vessel, and discussed the engineering method to calculate the shock impact of the APBR. Moreover, proposed the analysis method of APBR risk and design measures for risk reduction, which can provide theoretical justification for system safety design and its airworthiness compliance verification.
