Recent publications examining the flight of Eagles have shown that leading edge feather deflections occur on the lower surface of the wings in free flight to create a leading edge flap analogous to a Krueger flap system.Such passive high lift devices may be adaptable to the lifting surfaces of unmanned air vehicles (UAVs). This work is aimed to an application of a passive leading edge Krueger device which will deploy during the landing and takeoff stages of a UAV flight. Cont/d.
