An unmanned helicopter rotor force test experiment table belongs to the field of aviation and is used for verifying the accuracy of a mathematical model between a blade angle and a rotor force. The device is composed of an unmanned helicopter, a pipe clamp, a six-degree-of-freedom parallel motion platform, a pull pressure sensor, a linear sliding table and the like, the force of six supporting legs of the six-degree-of-freedom parallel motion platform is obtained through the pull pressure sensor, and the rotor force and the torque are calculated according to the force. The attitude control of the six-degree-of-freedom parallel motion platform is realized by controlling the motion of the linear sliding table, so that the experiment table can measure the rotor force of the unmanned helicopter in different attitudes. According to the invention, the whole unmanned helicopter is fixedly connected to the six-degree-of-freedom parallel motion platform for an experiment, so that the experiment operation is simple and convenient, and six rotor force experiments of the combination effect of the main rotor and the tail rotor can be carried out.
无人直升机旋翼力测试实验台属于航空领域,用于验证桨叶角与旋翼力之间的数学模型的准确性。本发明由无人直升机、管夹、六自由度并联运动平台、拉压力传感器、直线滑台等组成,通过拉压力传感器获得六自由度并联运动平台的六个支腿的力,据此计算获得旋翼力和力矩。本发明通过控制直线滑台的运动实现对六自由度并联运动平台的姿态控制,使得实验台可以测量无人直升机在不同姿态下的旋翼力。本发明将整个无人直升机固连在六自由度并联运动平台上进行实验,使得实验操作简洁方便,并且能进行主旋翼和尾旋翼合效果的六个旋翼力实验。
