摘要
本文对带外挂物二元机翼的颤振特性进行了理论和实验研究,主要分析机翼与外挂物之间俯仰联接刚度对颤振边界的影响。在大量算例的分析基础上,给出了颤振频率及颤振边界变化的一般规律及对颤振边界类型的一般判别方法,颤振模型的风洞实验验证了理论分析结果的正确性。
The flutter calculation and experiments are performed for two-dimensional wing with external store, the effects of pylon pitching stiffness on the flutter speed are investigated. The results show the general trend of variations of flutter frequency and flutter boundaries, and a simple criterion for the type of flutter boundary is presented. The reliablity of the conclusion is verified by wind tunnel tests.
