The invention discloses an unmanned helicopter rotor system test bed. The unmanned helicopter rotor system test bed comprises a rotor model used for test measurement; a power device used for providingpower for the operation of the rotor model; a rotor wing supporting device connected with the rotor wing model; the rotor wing supporting device comprises a rotor wing balance used for supporting andfixing the rotor wing model and a rotor wing support used for supporting and fixing the rotor wing balance and the rotor wing model. The transmission device is used for transmitting the rotary motionof the power device to the rotor wing model; the transmission device comprises a flexible coupling, a second vertical shaft, a rotor wing shaft, a torque sensor, a gear transmission device and a first vertical shaft, the bottom end of the first vertical shaft is connected with an output shaft of gear transmission. According to the invention, the transmission of vibration on the test bench to therotor wing is reduced, and the transmission of vibration of the rotor wing model to the test bench is avoided. Due to the fact that the flexible coupling comprises the two stainless steel diaphragm sets, larger radial, angular and axial deviations can be compensated.

    本发明公开了一种无人直升机旋翼系统试验台,包括:用于试验测量的旋翼模型;用于为旋翼模型运转提供动力的动力装置;与旋翼模型连接的旋翼支撑装置;旋翼支撑装置包括用于支撑固定旋翼模型的旋翼天平及用于支撑固定旋翼天平及旋翼模型的旋翼支架。传动装置用于将动力装置的旋转运动传递至旋翼模型,传动装置包括柔性联轴器、第二竖轴、旋翼轴、扭矩传感器、齿轮传动装置及底端与齿轮传动的输出轴连接的第一竖轴。在本申请减小了试验台上的振动向旋翼的传递,又避免了旋翼模型的振动向试验台的传递。由于柔性联轴器包括两组不锈钢膜片组,能够补偿更大的径向、角向和轴向的偏差。
