摘　　要：本文针对高亚声速飞机的荷兰滚模态设计要求和改善方法进行了研究,并叙述了飞机荷兰滚模态适航要求和军标要求及其他飞机公司的相关要求。以某高亚声速飞机为例,首先对飞机本体的荷兰滚模态特性进行分析研究,然后通过设计一个偏航阻尼器的来改善飞机的荷兰滚模态特性,并对高阶系统进行拟配降阶的手段,对增加偏航阻尼器后的飞机荷兰滚模态品质进行评估。基于对前人的偏航阻尼器的应用研究,提出了一些在偏航阻尼器实际应用时需要考虑的问题。对于类似荷兰滚模态阻尼低的飞机,本文对偏航阻尼器的设计和应用研究具有一定的参考价值。This paper studies the design requirements and improvement methods of dutch roll mode of high subsonic aircraft, and describes the airworthiness and military standard requirements of dutch roll mode. Taking a high subsonic aircraft as an example, firstly, the dutch roll mode characteristics of the aircraft body are analyzed and studied, then the dutch roll mode characteristics of the aircraft are improved by designing a yaw damper, and the dutch roll mode quality of the aircraft with yaw damper is evaluated by means of fitting and reducing the order of the high-order system. Based on the previous research on the application of yaw damper, some problems to be considered in the practical application of yaw damper are put forward. For the similar aircraft with low dutch roll mode damping, this paper has a worthy for the design and application of yaw damper.
