A pitch change actuation system (310) for changing the pitch of a propeller blade, the pitch change actuation system (310) comprising: an actuator body (340) defining an interior volume (360); and a chamber separation body (380) located within the interior volume (360) of the actuator body (340) and dividing the interior volume (360) into a first chamber (360a) and a second chamber (360b), the two chambers being fluidly separated by the chamber separation body (380). The first and second chambers (360a, 360b) are configured to receive a hydraulic fluid. The actuator body (360) is configured to translate relative to the chamber partition (380) in response to a hydraulic pressure difference between the first chamber (360a) and the second chamber (360b); and the translation of the actuator body (340) is configured to effect a change in propeller blade pitch.

    一种用于改变螺旋桨叶片桨距的桨距改变致动系统(310),所述桨距改变致动系统(310)包括:致动器主体(340),所述致动器主体限定内部体积(360);腔室分隔体(380),所述腔室分隔体位于所述致动器主体(340)的所述内部体积(360)内并且将所述内部体积(360)分成第一腔室(360a)和第二腔室(360b),所述两个腔室由所述腔室分隔体(380)流体分隔。所述第一腔室和所述第二腔室(360a、360b)被配置成接收液压流体。所述致动器主体(360)被配置成响应于所述第一腔室(360a)与所述第二腔室(360b)之间的液压差而相对于所述腔室分隔体(380)平移;并且所述致动器主体(340)的所述平移被配置成实现螺旋桨叶片桨距的变化。
