干式润滑线性执行器用于叶片转子控制

Dry lubricated linear actuator for in blade rotor control
Abstract:
A rotor blade assembly includes a rotor blade and a rotatable flap portion located along a span of the rotor blade. A linear actuator located inside the rotor blade is operably connected to the flap portion to rotate the flap portion about a flap axis and is absent oil, grease or other fluid lubricant. A rotary-winged aircraft includes an airframe and a main rotor assembly operably connected to the airframe. The main rotor assembly includes a plurality of rotor blade assemblies rotatable about a rotor assembly axis. At least one rotor blade assembly of the plurality of rotor blade assemblies includes a rotor blade and a rotatable flap portion located along a span of the rotor blade. A linear actuator positioned inside the rotor blade is operably connected to the flap portion to rotate the flap portion about a flap axis and is absent oil, grease or other fluid lubricant.
Abstract(Chinese):

转子叶片组件包括转子叶片和沿着转子叶片的跨度定位的可旋转翼片部分。 位于转子叶片内部的线性致动器可操作地连接到翼片部分，以使翼片部分围绕翼片轴线旋转，并且不存在油，油脂或其它流体润滑剂。 旋转飞机包括机身和可操作地连接到机身的主转子组件。 主转子组件包括可围绕转子组件轴线旋转的多个转子叶片组件。 多个转子叶片组件中的至少一个转子叶片组件包括转子叶片和沿着转子叶片的跨度定位的可旋转翼片部分。 定位在转子叶片内部的线性致动器可操作地连接到翼片部分，以使翼片部分围绕翼片轴线旋转，并且不存在油，油脂或其它流体润滑剂。
