摘要
以某飞机大展弦比机翼颤振风洞试验模型为例,对副翼偏转角变化导致的颤振问题进行了研究,给出了考虑舵面偏转效应的颤振分析方法,并通过试验加以验证。这些分析结论以及试验结果表明,副翼偏转角的变化在一定程度上会对大展弦比机翼的颤振特性产生重要影响,应当在飞机设计过程中予以考虑。
This paper gave a study on the question of the flutter of the high-aspect-ratio wings which were affected by aileron deflection by using a flutter model, and presented the flutter solving algorithm which accounts for the effects of rudder deflection, and performed an experimental verification as well. These analysis results and testing data indicated that the change of aileron deflection is very important for the flutter characteristics of high-aspect-ratio wings and should be considered in the aircraft design progress.
