On the Experimental and Application Study of High-Curvature Wing for Load-Task UAV

摘要

Present work studies the aerodynamic properties of high curvature wingfor UAV using wind tunnel test and CFD simulation. The high curvatureS1210 wing is adopted for experiment and simulation. The lift condition withdifferent AoA, the ground effect and wind speed effect are key topics to beexamined and discussed in detail. The real flight test also be carried out inthis work to verify the experiment and simulation results. Experimentalresults indicate that the high curvature wing not only has high AoA flightperformance but also possesses ground effect when flies near ground. Theground effect is dependent on wing span and happens at distance lower than1/4 span from the ground. Moreover, the flow over the wing surface does notseparate till 18o AoA. It illustrates that the high curvature S1210 wing is agood choice for task UAV. Especially the UAV needs to takeoff in shortdistance and fly at bad weather or strong head wind.
