    • Disclosed herein is a SCAS module (20) comprising one or more SCAS actuators (201,202) wherein each SCAS actuator comprises a piston (2013) arranged for linear motion within a hydraulic chamber in response to a flow of hydraulic fluid metered by a valve. The piston comprises a flexible rod or quill (2012) for providing a linear output along the first axis, the flexible rod or quill (2012) being mounted internally within an annular portion of the piston (2013) so that a space is defined around the flexible rod or quill (2012). The flexible rod or quill (2012) is capable of deforming into the surrounding space in order to accommodate movement of the flexible rod or quill (2012). The SCAS actuator may be mechanically integrated into an actuator system for a main or tail rotor of a helicopter. The actuator system may comprise a hydraulic actuator (10) for providing an output to a main or tail rotor of the helicopter; the SCAS module (20); a control valve (11) for controlling the flow of hydraulic fluid to the hydraulic actuator to vary the output provided to the main or tail rotor; and a linkage mechanism connecting the control valve to the hydraulic actuator, the linkage mechanism comprising a plurality of interconnected levers including a first lever (15) for receiving an input from a pilot, and a second input (16) arranged to receive an output from the SCAS module, wherein the linkage mechanism is configured to sum or otherwise combine the outputs from the first and second levers into a composite command and to transmit the composite command to the control valve (11) to control the flow of hydraulic fluid to the hydraulic actuator (10). Also disclosed is a helicopter comprising such an actuator system or SCAS module (20).

    • The control apparatus acquires an ideal velocity characteristic of a control surface(104,105), and the temperature of pressure oil of the actuator (11,12) to be tested and the operating speed of the control surface (104,105) when the actuator is attached to the control surface. The control apparatus corrects the ideal velocity characteristic of the control surface by using the pressure oil temperature and the control surface operating speed. The control apparatus sets an upper limit and a lower limit by using a predicted value for a fluctuation range for a fluctuation factor that causes a fluctuation of the control surface operating speed, with reference to the corrected ideal velocity characteristic, measures the pressure oil temperature and the operating speed by actuating the control surface (104,105), with the actuator to be tested placed in a damping mode, and determines whether the measured value falls within the range between the upper limit and the lower limit.
    • 控制装置获取控制表面(104,105)的理想速度特性,以及当致动器附接到控制表面(104,105)时待测试的致动器(11,12)的压力油的温度和控制表面(104,105)的操作速度 控制面。 控制装置通过使用压力油温度和控制表面操作速度来校正控制表面的理想速度特性。 控制装置参照修正后的理想速度特性,通过使用引起控制表面操作速度波动的波动因子的波动范围的预测值来设置上限和下限,测量压力油温度并且 通过致动控制表面(104,105)的操作速度,待测试的致动器置于阻尼模式,并确定测量值是否落入上限和下限之间的范围内。
