    • A swash plate assembly includes a rotationally stationary swash plate and rotational swash plate which rotates relative to the rotationally stationary swash plate through a bearing system. Each servo control rod is attached to the swash plate assembly to communicate control inputs thereto through a respective servo lug. Each servo lug defines a servo pivot point off an in-line plane inboard of the bearing system. As the servo lugs extend below the rotationally stationary swash plate, a relatively uncomplicated attachment arrangement is facilitated which provides for redundant locking features at a highly inspectable location which simplifies maintenance and increased safety. By locating the servo pivot point just inboard of the bearing system, an exceeding compact load path is defined thereby. The load path is defined from the servo control, to the servo lug, through the rotationally stationary swash plate, bearing system, the rotational swash plate, the rotor pitch control point and into the pitch control rod.
    • 旋转斜盘组件包括旋转固定的斜盘和旋转斜盘,其通过轴承系统相对于旋转固定的斜盘旋转。 每个伺服控制杆连接到旋转斜盘组件,以通过相应的伺服凸耳将控制输入与其通信。 每个伺服接线片将轴承系统的内侧平面内的伺服枢轴点定义为离线平面。 当伺服凸耳延伸到旋转固定的斜盘下方时,便于相对简单的附接装置,其在高度可检测的位置提供冗余的锁定特征,这简化了维护和增加的安全性。 通过将伺服枢轴点定位在轴承系统的内侧,由此定义了超紧凑的载荷路径。 负载路径由伺服控制,伺服接线片,旋转固定斜盘,轴承系统,旋转斜盘,转子桨距控制点和变桨控制杆定义。
