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.
본 발명은 상면의 형상이 평판형 또는 완만한 곡면형에서 요철형으로 형상 변형됨으로써 무인 비행체의 양력 및 양항비를 증가시킬 수 있는 무인 비행체의 주날개를 제공하기 위한 것이다. 본 발명에 의한 무인 비행체의 주날개는, 무인 비행체의 동체로부터 외측으로 연장된 날개 몸체와, 날개 몸체의 상면에 마련된 개구부와, 개구부를 덮기 위해 날개 몸체의 상면에 날개 몸체의 연장 방향으로 배치된 피봇 축에 대해 회전하도록 설치되는 가동 커버와, 가동 커버를 날개 몸체의 상면에 대해 하향 경사지게 되는 방향으로 회전시킬 수 있도록 날개 몸체의 내부에 설치되는 가동 커버 구동기와, 가동 커버가 날개 몸체의 상면에 대해 하향 경사지게 되는 방향으로 회전할 때 날개 몸체의 내부를 외부로 드러나지 않도록 차폐하기 위해 가동 커버와 연결되는 차폐기구를 포함한다.
