民用飞机驾驶舱门抵御穿透要求适航符合性评估方法

民用飞机驾驶舱门系统安装在飞机舱内，用于阻隔驾驶舱和客舱，除供机组人员正常进出驾驶舱外，必须具备防弹及防侵入功能，防止非机组人员抢夺飞机控制权，为机组成员提供安全保护。从驾驶舱门系统抵御穿透适航条款解读入手，对适航审定要求进行研究解读，提出一种民用飞机驾驶舱门抵御穿透试验方法，给出子弹选择、危险弹道确认、枪击点筛选、试验件构型准备等试验实施细节和要求，并以某型民用飞机驾驶舱门系统研发以及抵御穿透适航审定为基础对其进行验证。结果表明：本文提出的驾驶舱门抵御穿透试验方法有效，满足条款符合性，能够为飞机驾驶舱门设计研发以及适航符合性分析验证和相关条款的适航审定工作提供参考。

Evaluation method of airworthiness compliance of civil aircraft flight deck door against bullet penetration

The civil aircraft flight deck door system is installed in the aircraft cabin to block the cockpit area and cabin area. In addition to providing normal access to the cockpit, it must have bullet proof and intrusion prevention functions to prevent non-crew members from seizing control of the aircraft and provide safety protection for crew members. This paper starts with the interpretation of the airworthiness provisions for the flight deck door system to resist penetration, studies and interprets the airworthiness certification requirements, raises a evaluation method of civil aircraft flight deck door to resist penetration, gives the test implementation details and requirements such as bullet selection, dangerous trajectory confirmation, shooting point screening, test piece configuration preparation, and verifies it based on the development of a civil aircraft flight deck door system and the airworthiness certification for resisting penetration, The results show that the method is effective and can show the compliance of the clauses. The research content of this paper can provide reference for aircraft flight deck door design and development, airworthiness compliance analysis and verification, and airworthiness certification of relevant clauses.
