In the normal range of attack angles,the direction of aerodynamic pitch moment is the same with that of the increasing pitch angles. Pre-bend can increase aerodynamic pitch moment to a certain extent,and thereby can decrease total pitch moment.
结果表明,在正常攻角范围内,气动变桨力矩与桨距角增大方向一致,叶片预弯可以在一定程度上增大气动变桨力矩,从而减小总体变桨力矩。
