An unmanned aerial vehicle (10) of the present invention is configured to further comprise a drag reduction device (300) in a general unmanned aerial vehicle, wherein the drag reduction device (300) reduces air resistance applied to a fuselage (100) through a front panel (310) and an upper panel (320) variably operated by a lifting and lowering means (330) by being interlocked with a slope of the fuselage (100) changed in accordance with flight speed of the unmanned aerial vehicle, and reduces a vortex phenomenon generated in a lower portion of the fuselage (100) in accordance with an increase of the flight speed of the unmanned aerial vehicle through a lower panel (340) coupled to the lower portion of the fuselage (100), thereby reducing the entire drag.

    이 발명의 무인 비행체(10)는 일반적인 무인 비행체에다 항력 감소장치(300)를 더 갖도록 구성한 것으로서, 항력 감소장치(300)는 무인 비행체의 비행속도에 따라 변화하는 동체(100)의 기울어짐에 연동하여 승하강수단(330)에 의해 가변적으로 작동하는 전방패널(310) 및 상부패널(320)을 통해 동체(100)에 작용하는 공기저항을 감소시키고, 동체(100)의 하부에 결합되는 하부패널(340)을 통해 무인 비행체의 비행속도 증가에 따라 동체(100)의 하부에서 발생하는 와류현상을 감소시켜, 전체적인 항력을 감소시킨다.
