民用飞机防火系统适航审定技术分析与研究

火灾是影响运输类飞机安全运行的重要因素。飞机的防火系统为应急系统,通过对飞机的指定防护区进行探测、监控和报警并提供有效灭火,以保证飞机和机上人员的安全。鉴于此,防火系统与民用飞机的安全运行密切相关,也是适航条款要求的内容。旨在为民用飞机研制适航审定人员提供参考,同时也为防火系统适航审定工作提供相应的技术支撑。在分析民机防火系统功能要求和设计架构的基础上,依据中国民用航空规章第25部:运输类飞机适航标准(CCAR-25-R4-2011)的相应条款要求,分析了飞机防火系统可接受的符合性方法及防火系统验证试验中可接受的判据,给出防火系统在适航审查中的技术交联与工作协调。针对防火系统所涉及的各项条款,为局方提供了适航审查工作需要关注的审定要素和评审要求。研究有助于支持民机防火系统的安全设计与适航验证。

Research on the airworthiness certification technology of fire protection system for civil aircraft

Fire is an important factor to affect the safe operation of transportation aircraft. As an emergency system of aircraft, The fire protection system can detect, monitor and alarm the designated protection area of the aircraft and provide effective fire fighting to ensure the safety of the aircraft and the personnel on board. Therefore, fire protection system is closely related to the flight safety of civil aircraft, and is also the content of airworthiness requirements. The purpose is to provide reference for airworthiness certification personnel on civil aircraft development and provide corresponding technical support for airworthiness certification of fire protection system. Based on the analysis of the functional requirements and design architecture of civil aircraft fire protection system, and in accordance with the requirements of CCAR 25, the corresponding acceptable compliance methods of aircraft fire protection system and the acceptable criteria in the verification test of fire protection system were analyzed. And the technical cross-linking and work coordination of the fire protection system in the airworthiness review were given. In view of the various clauses involved in the fire protection system, the certification elements and requirements for airworthiness review were provided for CAAC. The research is helpful to support the safety design and airworthiness verification of civil aircraft fire protection system.
