MAIN WINGS WITH ENHANCED AERODYNAMIC PERFORMANCE FOR UNMANNED AERIAL VEHICLE

摘要

The present invention provides a main wing for an unmanned aerial vehicle which changes a shape of an upper surface thereof from a flat shape or a slightly curved shape to an irregular shape to increase a lift force and a lift-to-drag ratio of an unmanned aerial vehicle. According to the present invention, the main wing for an unmanned aerial vehicle comprises: a wing body extended from a fuselage of an unmanned aerial vehicle to the outside; an opening part disposed on an upper surface of the wing body; a movable cover installed on the upper surface of the wing body to be rotated about a pivot arranged in the extension direction of the wing body to cover the opening part; a movable cover drive device installed in the wing body to rotate the movable cover in a direction in which the movable cover is inclined downwards with respect to the upper surface of the wing body; and a shielding mechanism connected to the movable cover to shield the inside of the wing body from the outside when the movable cover rotates in the direction in which the movable cover is inclined downwards with respect to the upper surface of the wing body.
