    • A variable rotor blade mechanism for use in a gas turbine engine comprises a blade rotor, a blade, a harmonic drive system, a stepper motor and a bracket. The blade rotor rotates absolutely about an axial engine centerline during operation of the gas turbine engine. The blade extends radially from the blade rotor and is configured to be adjustable by rotation about a radial axis. The harmonic drive system is mounted to the blade rotor and connected to the blade to rotate the blade about the radial axis. The stepper motor drives the harmonic drive with relative rotational input with respect to the absolute rotation of the blade rotor. The bracket is disposed about the engine centerline and supports the stepper motor stationary with respect to the rotation of blade rotor such that the relative rotational input to the stepper motor is generated.
    • 用于燃气涡轮发动机的可变转子叶片机构包括叶片转子,叶片,谐波驱动系统,步进马达和支架。 在燃气涡轮发动机的运行期间,叶片转子绝对围绕轴向发动机中心线旋转。 叶片从叶片转子径向延伸并且构造成通过围绕径向轴线的旋转来调节。 谐波驱动系统安装到叶片转子并连接到叶片以使叶片围绕径向轴线旋转。 步进电机以相对于叶片转子的绝对转动的相对旋转输入驱动谐波驱动器。 支架围绕发动机中心线设置,并且相对于叶片转子的旋转支撑步进马达固定,使得产生对步进马达的相对旋转输入。
