结合工程实践对飞机的气动伺服弹性稳定性检查的设计思想、理论及试验方法进行了探讨。内容包括理论背景、频率响应分析、伺服颤振分析、状态方程法以及地面耦合试验、风洞稳定性试验和飞行试验验证介绍等。在此基础上用某型飞机作为实例验证了气动伺服弹性的工程设计方法,进一步证实了本文所描述的分析和试验技术的有效性和实用性。最后提出了未来气动伺服弹性研究应开展的工作。
Combining with the engineering practice, the design idea, theory and test method of aircraft servo pneumatic stability checking are discussed. The contents include theoretical background, frequency response analysis, servo flutter analysis, state equation method and ground coupling test, wind tunnel stability test and flight test validation introduction. Based on this, the engineering design method of aerodynamic servo elasticity was verified with a certain type of aircraft, further confirming the validity and practicability of the analytical and experimental techniques described in this paper. Finally, the future research work on pneumatic servo elasticity should be carried out.
