【 摘 要 】

Flight speed is an important factor that affects flapping-wing propulsion. This study conducted tests on a self-designed rotatory force-measuring platform and simulated different inflow conditions by changing the rotatory angular velocity. An M-shaped bending-surface feather fan was selected as the test model, and the rotatory platform was rotated at different speeds under different propulsion so that the flapping-wing propulsion at different inflow velocities could be measured. Moreover, the wind speed corresponding to the maximum propulsion was determined. The results show that as wind velocity increases within a certain range, the propulsion first increases, then decreases, and finally increases until reaching a maximum wind velocity value of 7.3 m/s.
