民用飞机飞控系统舵面卡阻试飞方法研究

某型民用飞机是我国首次全面采用CCAR25部进行适航取证的飞机型号，民航当局特别关注飞控系统舵面卡阻故障状态下的飞行试验验证。为了保证该民用飞机飞控系统舵面卡阻试飞顺利开展，针对舵面卡阻方案设置及卡阻试飞方法进行深入研究，提出三种舵面卡阻方案，对各方案优缺点进行分析，重点介绍卡阻故障模拟方案的原理及试飞安全控制方案，并根据适航标准要求制订具体的卡阻试飞方法；通过铁鸟台试验对卡阻故障模拟方案和卡阻试飞方法进行验证。结果表明：卡阻故障模拟方案满足舵面卡阻要求，卡阻试飞方案具有较高的可行性。

Flight Test Method Study of civilian airplane Flight Control Surfaces Jamming

A certain civil aircraft is the first airplane type to fully use CCAR25 for validating the airworthiness in our country ,the flight test of control surfaces jammed situation is highly focused by CAAC .To ensure that the civil aircraft flight control surfaces jamming flight test will be developed successfully ,surfaces jammed scheme and fight test method are studied .Three schemes of surfaces jamming are introduced and analyzed ,the principle and flight safety control scenario of the front-injected method are emphasized .Finally typical surfaces jammed simulation flight test method is formed .The scheme and method are validated on the civil aircraft iron bed ,the results indicate that the front-injected method meets the requirements of surfaces jamming and is highly feasible .
