Analysis of Aerodynamic Characteristics of UAV Wing under Icing Condition

With the development of UAV technology, it has been widely used in more and more fields. At present, UAV has the characteristics of quick response, high efficiency, complete functions and complex internal structure. When unmanned aerial vehicle (UAV) flies in complex weather conditions, its wing surface is also easy to freeze. After the wing freezes, it not only increases the flight weight, but also changes the aerodynamic shape of the UAV, resulting in the increase of wing resistance, the decrease of lift, the decrease of stall angle of attack, the increase of stall speed and the deterioration of maneuverability and stability, which poses a serious threat to flight safety. In this study, the aerodynamic characteristics and structural characteristics of UAV icing wings are analyzed based on hydrodynamics and structural dynamics from the perspective of UAV safety.
