The invention discloses a high Reynolds number single propeller aerodynamic force measurement test device and a measurement method thereof, and belongs to the field of wind tunnel tests. Comprising a rotating shaft balance, an extended shaft body, a torque sensor, a turbine air motor, a motor mounting seat and a supporting rod. The propeller model is connected with the rotating shaft balance, the rotating shaft balance is connected with the torque sensor through the extended shaft body, the torque sensor is connected with the turbine air motor, the strain gauge measures the blade bending moment of the propeller model, the rotating shaft balance measures the aerodynamic force of the propeller model, and the torque sensor monitors the output shaft torque of the turbine air motor. The measuring method comprises the steps that the testing device is installed on a pressurizing wind tunnel testing section, the pressurizing wind tunnel is utilized, the density of a testing flow field is increased by increasing the internal pressure of the wind tunnel, and therefore the testing Reynolds number is increased, and a high Reynolds number propeller aircraft slip flow test is achieved. According to the invention, the accuracy of the propeller model wind tunnel test is improved, and the test cost is reduced.
