Provided is a variable main wing of an unmanned aerial vehicle, which is improved to show optimized aerodynamic performance by varying the shape of the front end thereof according to flying conditions, such as the angle of attack while flying or the like. The variable main wing of an unmanned aerial vehicle according to the present invention comprises: a wing body which is extended outward from the fuselage of the unmanned aerial vehicle; an opening part which is prepared on the front end of the wing body in the longitudinal direction of the wing body; a flexible cover which is coupled to the wing body to cover the opening part of the wing body; a pressing member which is installed inside the wing body to be drawn out of the wing body and presses the flexible cover to allow the flexible cover to protrude from the front of the wing body; and a pressing member drive unit which is installed inside the wing body to draw the pressing member into/out of the wing body.
본 발명은 비행 중 받음각 등 비행 상황에 따라 선단부의 형상을 가변함으로써 최적의 공력성능을 발휘할 수 있도록 개선된 무인 비행체의 가변형 주날개를 제공하기 위한 것이다. 본 발명에 의한 무인 비행체의 가변형 주날개는, 무인 비행체의 동체로부터 외측으로 연장된 날개 몸체와, 날개 몸체의 선단에 날개 몸체의 길이 방향으로 마련된 개방부와, 날개 몸체의 개방부를 덮도록 날개 몸체에 결합되는 탄력성 커버와, 탄력성 커버를 날개 몸체의 전방으로 가압하여 돌출시키기 위해 날개 몸체의 내부에 진퇴 가능하게 설치되는 가압부재와, 가압부재를 진퇴시키기 위해 날개 몸체의 내부에 설치되는 가압부재 구동기를 포함한다.
