The invention relates to a trim actuator for a horizontal stabilizer and a method of controlling a horizontal stabilizer. A trim actuator (102) for a horizontal stabilizer (210) includes a power screw (106), a rotary actuator (104) configured to rotate the power screw (106), and a nut (108) configured to translate along the power screw (106) when the power screw (106) is rotated. The trim actuator (102) further includes an anti-reverse drive mechanism (114) configured to prevent rotation of the power screw (106) in a first rotational direction when a first force is applied to the nut (108) in a first axial direction, and prevent the power screw (106) from rotating in a second rotational direction opposite the first rotational direction when a second force is applied to the nut (108) in a second axial direction. The trim actuator (102) further includes a sensor (120) configured to measure an internal load of the anti-reverse drive mechanism (114) when a first force is applied to the nut (108) in a first axial direction or when a second force is applied to the nut (108) in a second axial direction.

    本发明涉及用于水平安定面的配平致动器以及控制水平安定面的方法。用于水平安定面(210)的配平致动器(102)包括动力螺杆(106)、被配置为旋转动力螺杆(106)的旋转致动器(104)以及被配置为当动力螺杆(106)旋转时沿着动力螺杆(106)平移的螺母(108)。配平致动器(102)还包括防倒退驱动机构(114),该防倒退驱动机构被配置为当第一力沿第一轴向方向被施加到螺母(108)时防止动力螺杆(106)在第一旋转方向上旋转,并且当第二力沿第二轴向方向被施加到螺母(108)时防止动力螺杆(106)在与第一旋转方向相反的第二旋转方向上旋转。配平致动器(102)进一步包括传感器(120),该传感器被配置为测量当第一力沿第一轴向方向被施加到螺母(108)时或当第二力沿第二轴向方向被施加到螺母(108)时防倒退驱动机构(114)的内部负荷。
