Xue Haifeng,Xiang Jinwu,Zhang Xiaogu,Li Shuqiang
Strategic Study of CAE 2007, Volume 9, Issue 9, Pages 58-62
The influence of pitch/lag coupling on helicopter air resonance is investigated First, helicopter air resonance equations of motion considering pitch/lag coupling is derivedrelated analysis model and calculation programs are built to study the effect of pitch/lag coupling on helicopterapproximate expression of mutual excitation of different degrees of freedom, the explanations of the helicopter The results indicated that the positive pitch/lag coupling can restrain the instability of helicopter
