以某型飞机垂尾为研究对象,设计了带方向舵的垂尾跨音速颤振风洞试验模型,并通过地面振动试验对其进行验证。研究表明,模型可以准确模拟垂尾刚度,方向舵旋转刚度稳定,模型取得了较好的试验效果。
Taking the tail of a certain type of aircraft as the research object, a vertical tail-twitch wind tunnel test model with rudder is designed and verified by ground vibration test. The results show that the model can accurately simulate the vertical stiffness and the rotational stiffness of the rudder is stable, and the model has achieved good experimental results.
