飞机设计中的颤振综合分析

Ｋ８教练飞机设计中的颤振分析包括数值计算、风洞试验、地面试验和飞行试验等工作，这些工作是在飞机设计和制造的不同阶段进行的，且彼此相关密不可分。文中对每一项工作作了评述。指出若仅采用其中的某一项分析或试验表明飞机的颤特性尚有不充分之处。只有将各种分析和试验结果进行相互验证、比较和修正，并进行综合分析，才能得出该飞机颤振安全的正确结论。

Synthetic Analysis of Flutter in Aircraft Design

In the design of K8 aircrafts, flutter analysis includes flutter computation, ground vibration test, wind tunnel test and flight flutter test. These jobs are made in the different stages of the aircraft design and the aircraft manufacture, and they are coherent with each other. In this paper, every job is discussed. It is not sufficient if flutter certification is based upon only analysis or test of the aircraft. After making systematic analysis for the results of all analyses or tests, the accurate conclusion of aircraft flutter characteristics can be received.
