Pitch angle control system can change pitch, accordingly regulate the rotational speed and output power by adjusting blade incidence of wind-driven device.
变桨距是通过改变风力机叶片桨距角来改变风力机的转速，从而调整发电机输出功率。
The influence of incidence Angle, blade's flexure Angle and exit conditions on the effect of positive blade flexure is discussed.
讨论了冲角、叶片弯曲角和出口条件对叶片正弯曲作用的影响。
The combination of the slot with an optimized blade design significantly reduces the secondary flow losses compared to the original turbine stator, especially at large negative angles of incidence.
经联合造型后的叶栅与原始叶栅相比在各个攻角下的流动损失均有大幅度降低，大负攻角下效果尤为明显。
