The invention relates to control surface actuator assemblies, aircraft hydraulic systems including the same, and associated aircraft and methods. A control surface actuator assembly includes a flight control surface operatively coupled to a support structure, a torque-generating hydraulic actuator configured to apply a torque to pivot the flight control surface, and a variable horn radius (VHR) hydraulic actuator configured to vary an actuator moment arm length for pivoting the flight control surface. In some examples, an aircraft hydraulic system includes such control surface actuator assemblies, and an aircraft includes such aircraft hydraulic systems. In some examples, a method of operating one or more flight control surfaces of an aircraft includes controlling a selected flight control surface by adjusting, with a VHR hydraulic actuator, an actuator moment arm length corresponding to the selected flight control surface and pivoting, with a torque-generating hydraulic actuator, the selected flight control surface.

    本文涉及控制面致动器组件、包括其的飞行器液压系统以及相关联的飞行器和方法。控制面致动器组件包括飞行控制面、扭矩产生液压致动器和可变机臂半径(VHR)液压致动器,该飞行控制面可操作地耦接至支撑结构,该扭矩产生液压致动器被配置成施加扭矩以枢转飞行控制面,该VHR液压致动器被配置成改变致动器力矩臂长度以用于枢转飞行控制面。在一些示例中,飞行器液压系统包括此类控制面致动器组件,并且飞行器包括此类飞行器液压系统。在一些示例中,操作飞行器的一个或多个飞行控制面的方法包括:通过用VHR液压致动器调节对应于所选的飞行控制面的致动器力矩臂长度以及用扭矩产生液压致动器枢转所选的飞行控制面,来控制所选的飞行控制面。
