The three-dimensional force sensor aerodynamic test plays a crucial role in verifying the design method of hummingbird flapping wing aircraft and optimizing and improving the system characteristic parameters of the aircraft. A newly developed three-dimensional force sensor with low cost, simple structure and high performance is introduced, which is used in the aerodynamic test platform of flapping wing aircraft, and the design and static calibration method of three-dimensional force sensor are introduced. Firstly, the feasibility of the structural design of the test platform is verified by the microvariable kinematics modeling of the elastic mechanism. Then, the decoupling calibration experiment of the test platform was carried out, and the nonlinearity error of the sensor was less than1.25 %, the coupling error was less than 3.16%, and the sensitivity was greater than 1.1V/N. Finally, through the aerodynamic test of a smaller hummingbird micro-flapping wing vehicle, the quantitative evaluation data of the aerodynamic force of such a miniature flapping wing aircraft with the change of influencing parameters was obtained, which provided effective help for the indoor and outdoor flight and maneuverable flight of the micro-flapping wing.
