| Due to the high risk and cost associated with conducting flight experiments on aircraft, ground-based wind tunnel experiments that simulate actual flight conditions based on the principles of relativity are an essential research method. This paper presents the design of an integrated wind tunnel test platform that combines dynamics and control, capable of real-time monitoring of the aerodynamic characteristics of an aircraft. It provides equivalent feedback on changes in position, attitude, and velocity, thereby simulating actual flight conditions. Using the F450 aircraft model as the experimental subject, this study investigates its performance, determining the relationship between different motor powers and payload with endurance time during hovering, finding the optimal flight efficiency range under various flight speeds, and establishing the maximum flight speed equivalent to the maximum crosswind limit through specific payload varying wind speed tests. Additionally, the aircraft's handling characteristics under wind shear conditions are examined. The results indicate that this platform effectively observes and analyzes flight efficiency, limits, control, and crosswind resistance, offering an efficient, low-cost, and low-risk testing solution for flight performance studies, significantly reducing the cost and risk of actual flight experiments. |
