摘要

摘要: 基于国内运输类飞机适航认证需要,系统分析了CCAR/FAR25.981条款变迁历史、内涵与指标要求;并从型号申请人的角度针对适航取证过程中拟采取的符合性方法开展了初步探讨,归纳总结出不同类型油箱可燃性指标及符合性验证方法;在此基础上,研究了美国联邦航空局（FAA）官方颁布的油箱可燃性评估应用程序。研究表明:①燃油箱可燃性适航符合性验证工作重点是可燃性暴露时间评估方法的应用;不同类型油箱,所允许的机队平均可燃性暴露水平不同,其中,机身油箱是适航审定关注的重点;②为了确定隔舱的平均燃油温度、气相空间温度和油箱壁面温度,并根据平均燃油温度计算燃油箱隔舱的热时间常数和平衡温差以用于蒙特卡洛分析,最经济有效的方法是建立燃油箱热模型;③计算机队平均可燃性暴露时间的难点在于平衡温差与时间常数的准确获取,对于该问题,可以通过遗传算法追踪来予以解决。

Abstract: Based on the airworthiness certification needs of domestic transport aircraft, the changing history, the connotation and index requirements of CCAR/FAR25.981 were systematically analyzed. From the perspective of the model applicant, a preliminary discussion on the conformity methods to be adopted in the process of airworthiness certification was conducted. Meanwhile, the flammability indexes and conformity verification methods of different types of fuel tanks were summarized. Subsequently, the fuel tank flammability assessment application issued by Federal Aviation Administration（FAA） was studied. Research shows that: (1) the revision of airworthiness regulations is the result of the development of fuel tank safety technology and knowledge level, and the airworthiness regulations must be closely combined with the current mainstream technology level; (2) different types of fuel tanks allow different levels of fleet average flammability exposure, among which fuselage fuel tank is the focus of airworthiness certification; (3) the difficulty of the average flammability exposure time of the computer team lies in the accurate acquisition of the balance temperature difference and time constant, which can be solved through establishment of fuel tank thermal model and genetic algorithm tracking.
