摘要

摘要: 直升机在前飞状态下的稳定性研究比悬停时复杂得多.主要针对直升机前飞状态下的空中共振的稳定性加以研究.计算和分析了某些典型情况的特征值、特征向量和各自由度之间的相互作用.对前飞时的相关参数对直升机空中共振稳定性的影响等方面进行了研究.从分析各个自由度间的相互作用入手揭示直升机空中共振的机理.

Abstract: It is more difficult to investigate the helicopter dynamic stability in forward flight than in hover.Air resonance dynamic stability in forward flight is examined in the paper.The eigenvalues,eigenvectors and mutual excitation of different degrees of freedom of representative instance are calculated and analyzed.The effect of parameters on air resonance dynamic stability was studied through the analysis of mutual excitation of different degrees of freedom.
