The invention discloses an unmanned helicopter main rotor lift force test board, belongs to the technical field of test devices, and solves the problem that the flight lift force of a main rotor cannot be tested on the ground at present. The test board comprises a main rotor system, a belt wheel system, a motor, a first fixing frame, a second fixing frame, a pull pressure sensor, a counterweight device, a test bed and a third fixing frame; the fixed frame I is placed on the test bed; the second fixing frame is located above the first fixing frame, and one end of the second fixing frame is connected with the first fixing frame through a bearing A; the middle of the second fixing frame is connected with the first fixing frame through a pull pressure sensor. The third fixing frame is placed at the other end of the first fixing frame, and the balance weight device is placed on the third fixing frame. The motor, the belt wheel system and the main rotor system are all installed on the second fixing frame, and the motor is connected with the main rotor system through the belt wheel system. The main rotor system of the unmanned aerial vehicle can be subjected to lift test on the ground, and the safety and reliability of the main rotor system are ensured.
