Analysis on Wind Resistance Index of Multi-rotor UAV

Since multi-rotor UAV possesses simple structure and light weight, it is likely to be affected by the outside wind field. So far, researches on the wind resistance of multi-rotor UAV mostly focus on the control method of anti-interference. However, a common index to measure the ability of wind resistance is still absent. For this reason, the article does quantitative analysis on the induced velocity of propellers and propeller thrust of a multi-rotor UAV. What's more, the article analyzes the influence of horizontal wind on the drone and builds a model on a multi-rotor UAV in the wind field. Finally, the article puts forward a parameter to measure the wind resistance ability of a multi-rotor UAV.
