摘要
颤振和气动伺服弹性失稳是危险的气动弹性现象,在飞机设计的最后阶段需要依靠飞行试验来预测气动弹性稳定边界。回顾了传统颤振试飞中的模态阻尼法和系统稳定性分析法,比较了各方法的应用特点,并重点介绍了鲁棒稳定性分析μ方法及其在气动伺服弹性试飞中的应用。最后总结了NASA德莱顿研究中心近年在气动弹性试飞方面的工作,供研究人员参考。
Flutter and aeroservoelastic instability are dangerous aeroelastic problems and the critical boundary should be predicted by flight test in the terminal stage of the aircraft design. Three types of methods and their features are reviewed, including the traditional modal damping method, system stability analysis method and robust stability μ-analysis method. And the recent studies on aeroelastic flight tests of NASA Dryden Flight Test Center are introduced.
