A propeller control system for controlling a blade pitch angle including: a propeller blade extending from a blade base, the propeller blade being configured to rotate around a longitudinal axis to generate thrust for the propeller blade and rotate around a pitch change axis to adjust the blade pitch angle, wherein the pitch change axis extends through a center point of the blade base; a trunnion pin operably connected to the blade base at a location offset from the center point; a yoke plate operably connected to the trunnion pin; an actuator configured to move the yoke plate linearly along the longitudinal axis to rotate the trunnion pin and the propeller blade around the pitch change axis; and a transfer tube operably connected to the yoke plate, the transfer tube being free to rotate around the longitudinal axis as the actuator moves the yoke plate linearly along the longitudinal axis.
一种用于控制桨叶俯仰角的螺旋桨控制系统包括:螺旋桨桨叶,所述螺旋桨桨叶从桨叶基部延伸,所述螺旋桨桨叶被配置为围绕纵向轴线旋转以产生针对螺旋桨桨叶的推力并且围绕俯仰改变轴线旋转以调整桨叶俯仰角,其中所述俯仰改变轴线延伸穿过桨叶基部的中心点;耳轴销,所述耳轴销在相对于中心点偏移的位置处可操作地连接到桨叶基部;轭板,所述轭板可操作地连接到耳轴销;致动器,所述致动器被配置为使轭板沿着纵向轴线线性地移动,以使耳轴销和螺旋桨桨叶围绕俯仰改变轴线旋转;以及转移管,所述转移管可操作地连接到轭板,随着致动器使轭板沿着纵向轴线线性地移动,所述转移管可围绕纵向轴线自由旋转。
