In order to evaluate the aerodynamics layout and flight performance of the aircraft, a aerodynamic coefficients measuring method with moving model is proposed, and a moving model measuring system is developed to simulate the motion of the aircraft in the air through the moving model, whose construction mainly includes the carrier, measuring stand, six-component balance, wind speed measurement module, data acquisition module, control module, portable computer and other parts; The measuring system can simulate the flight state of the vehicle, accurately predict the aerodynamic characteristics of the vehicle in each motion state, and make real-time measurements of the flow field coefficients; the numerical simulation analysis and wind tunnel experiments have been conducted to compare and verify the data, and the results show that the measuring system can accurately obtain the aerodynamic characteristics data of the model; In addition, the system is also scalable and versatile, and can be used with other carriers such as rocket sleds to carry out high-speed moving model aerodynamic coefficients measurements.
