Study of opening holes on the wing of flapping-wing MAV and its effect on aerodynamic characteristic

In this paper,we described the basic principle of lift production of the flapping wing MAV at first,and developed a method of boring holes on the wing to acquire the flapping-lift.The basal aerodynamic influence have been studied by wind tunnel experiment,the result indicated that the perforated wing can effectively obtain flapping-lift and reduce energy consume,but would lose some thrust.The wind tunnel experiment was arranged by perpendicular design,and built 2 ranks response surface model about the parameters in experiment,then used this model to estimate the aerodynamic performance of the perforated wing.Its shown that the maximal takeoff weight between the perforated wing and the imperforate wing was equivalent,but the perforated wing had preferably performance and less power consumption in low velocity,it's hopeful to realize hovering by this method.
