  • 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.
