正常类飞机CCAR23.2205符合性验证方法分析

为推进正常类飞机CCAR23.2205“系统和结构的相互影响”适航条款符合性验证工作,面向适航条款要求,结合国内飞机强度设计工作实际,梳理出一套“系统和结构的相互影响”条款的符合性验证方法。分故障类型筛选、系统正常情况评估、系统失效情况评估、系统失效指示和失效情况飞机签派,共5个具体步骤系统阐述申请人的符合性验证思路及各步骤中相关专业必须开展的计算分析工作。为正常类飞机结构强度专业的适航条款符合性验证工作提供一定的启发。

To promote the compliance verification work of the airworthiness requirement CCAR23.2205"Interactions between Systems and Structures"for normal category aircraft,a set of compliance verification methods for the"Interactions between Systems and Structures"requirement have been developed based on the domestic aircraft strength design work.The methods include five specific steps:filtering of failure types,evaluation of system performance under normal conditions,evaluation of system performance under failure conditions,indication of system failure and dispatch of aircraft under failure conditions.This method provides a detailed explanation of the compliance verification approach and the necessary computational analysis work to be carried out in each step,which provides some inspiration for the verification of airworthiness clause compliance of normal aircraft structural strength specialty.
