Unmanned helicopter tail rotor thrust testboard

The invention provides an unmanned helicopter tail rotor thrust test bench, and belongs to the technical field of unmanned helicopter testing. The tail rotor thrust test board is used for solving the problems that the thrust of the tail rotor of the unmanned helicopter cannot be independently tested on the ground and the test result is inaccurate at present. The device specifically comprises a fixing frame, a motor support, a motor, a tension meter and a tail rotor angle adjusting mechanism. Wherein the motor bracket is connected with the fixing frame and can transversely swing around the fixing frame; the motor and the tail rotor to be tested are respectively mounted at two opposite ends of the motor bracket; an output shaft of the motor is connected with the tail rotor main shaft through a power transmission mechanism so as to drive the tail rotor main shaft to rotate; a tension meter is arranged under the tail rotor wing, and the two ends of the tension meter are connected with the fixing frame and the mot
