民用飞机大侧风起降试飞关键技术研究

Flight Test Technology Research on Crosswind Takeoff and Landing of Civil Airplane

某型民用飞机的大侧风起降试飞是我国首次严格按照CCAR25部的要求将相关试飞技术完整运用于民用飞机。结合该飞机的大侧风起降试飞,对飞机理论抗侧风量的预测方法进行了研究和验证,提出了将飞机的理论抗侧风量换算至全重量范围内的方法,并详细阐述了民用飞机大侧风起降试飞过程中的关键试飞技术,可为其他运输类飞机的大侧风起降试飞提供重要的参考。

In China, the critical flight test technology of crosswind takeoff and landing was first applied to civil airplane according to CCAR-25 when the interrelated flight test of a civil airplane was carried out. Based on the test, this paper researched and validated a method of evaluating an airplane＇s capability of resistance to crosswind, brought out a method of converting an airplane＇s capability of resistance to crosswind within the whole weight range of the airplane, and expatiated the critical flight test technology of the crosswind takeoff and landing flight test of civil airplane. Those can provide an important reference for other transport category airplane.
