运输类飞机“最小风险炸弹位置”的研究进展

"最小风险炸弹位置"(LRBL)是运输类飞机型号合格审定最新的客舱安保要求之一。基于LRBL适航要求及相关的咨询通告,针对LRBL周围结构和系统的设计与布局、以及爆炸发生后的次生影响和应对措施,综述了飞机结构在内爆冲击载荷作用下的响应特性及失效模式的研究进展,梳理了人体在爆炸冲击波作用下的损伤机理及损伤模型,明确了爆炸碎片的破坏概率模型,总结了国内外抗爆容器的设计特征及优缺点,最后简述了中国民航大学天津市民用航空器适航与维修重点实验室为研究机身结构在内爆载荷下的响应特性所做的相关技术研究。

Research Progress on the Basic Technologies of Airworthiness Verification of Least Risk Bomb Location

The design of Least Risk Bomb Location (LRBL) is directly related to the flight safety of transport aircraft, and the research on airworthiness compliance verification of LRBL in our country is still in its infancy.According to LRBL airworthiness requirements and AC 25.795-6 ,based on design and layout of structures and systems around LRBL and the secondary effects and countermeasures after the explosion, the research progress of the aircraft structure response characteristics under internal explosive load, impact damage of human, explosion-proof container design and projectile damage caused by explosion fragments is reviewed. The related project studies to study the response of fuselage structures under internal explosive load are described briefly.
