Experimental Investigation of Aerodynamics of Feather-Covered Flapping Wing

摘要: Avian flight has an outstanding performance than the manmade flapping wing MAVs. Considering that feather is light and strong, a new type of was designed made, whose skeleton carbon fiber rods covered by goose feathers as skin. Its aerodynamics tested experiments can be compared with conventional artificial wings made polyester membrane The results showed feathered could generate more lift in same kinematics because have slots between upstroke process, which mainly reduce negative lift. At time, power consumption also decreased significantly, due to decrease fluctuating range periodic curve, reduced offset thrusts generated are similar each other, increases increase frequency. In general, aerodynamic performances superior wings.
