A pitch controller rotates each blade around a bearing, setting it to the best angle for the wind speed.
同时间距控制装置会根据风速旋转安装在轴承上的风叶，保持在最佳角度。
The simplest way to dampen a helicopter's noise is to increase the Angle of the rotor's blades, also called the pitch, and slow them down.
要降低噪音，最简单的方法是增大旋翼桨叶的夹角，也叫“节距”，或是降低转速。
The main blades pitch Angle is controlled by the up and down movements of the swashplate.
大桨的螺距角度是由倾斜盘的上升和下降动作控制的。
