| 摘 要： | 由于受空气压缩性的影响,飞机的颤振速度在跨声速区附近一般会出现较大降低。为解决此问题,简要分析了跨声速区颤振"凹坑"形成的机理,并结合某型飞机的颤振试飞,提出了跨声速区的颤振试飞方法,并给出了数据分析处理结果和结论。

| Abstract: | Influenced by the air's compressibility, the flutter speed of aircraft is usually reduced near the transonic region.To solve the problem,this paper briefly analyzes the mechanism of the pit formation of transonic flutter.With the flutter flight test of a certain type of aircraft, a transonic flutter test method is proposed, and the data analysis results and conclusions are given. |
