The present invention relates to a hybrid unmanned aircraft capable of reducing drag. More specifically, the present invention relates to a hybrid unmanned aircraft capable of reducing drag, which, when the aircraft flies horizontally, hides a rotor generating lift inside the aircraft that is exposed and operates when the aircraft flies vertically. According to an embodiment of the present invention, the hybrid unmanned aircraft capable of reducing drag comprises: a streamlined fuselage unit; main wing units placed on both sides of the center of the fuselage unit; main rotor units mounted inside the main wing units; a rear rotor unit mounted inside the fuselage unit which meets the rear surface of the main wing units; main opening/closing units which open the main rotor units upwards and downwards; a rear opening/closing unit which exposes the rear rotor unit backwards; and a tail wing unit placed on the rear side of the fuselage unit. When the aircraft vertically takes off or lands, the main opening/closing units are opened to expose the main rotor units inside the main wing units and to make the rear opening/closing unit move backwards, thereby making the rear rotor unit protrude towards the rear side of the main wing units to allow exposure. When the aircraft flies horizontally, the main opening/closing units are closed to make the main rotor units hidden inside the main wing units, and the rear opening/closing unit is moved forward to pull the rear rotor unit into the rear surface of the main wing units to be hidden.

    본 발명은 항력 감소 하이브리드 무인항공기에 관한 것으로서, 보다 상세하게는 양력을 발생시키는 로터(rotor)가 항공기의 수평 비행시에 항공기의 내부에 숨겨지고 수직 비행시에 노출되어 작동되기 위한 항력 감소 하이브리드 무인항공기에 관한 것이다. 본 발명의 일실시 예에 따른 항력 감소 하이브리드 무인항공기는 유선형으로 마련되는 동체부와, 상기 동체부의 중심부 양옆으로 마련되는 메인날개부와, 상기 메인날개부 내에 장착되는 메인로터부와, 상기 메인날개부 후면과 만나는 상기 동체부 내에 장착되는 후측로터부와, 상기 메인로터부를 상하로 개방시키는 메인개폐부와, 상기 후측로터부를 후방으로 노출시키는 후측개폐부, 및 상기 동체부의 후방에 마련되는 꼬리날개부를 포함하고, 수직 이착륙시 상기 메인개폐부를 오픈(open)시켜 상기 메인날개부 내에서 상기 메인로터부를 노출시키고, 상기 후측개폐부를 후진시켜 상기 후측로터부를 상기 메인날개부 후방으로 돌출되게 하여 노출시키며, 수평 비행시 상기 메인개폐부를 클로즈(close)시켜 상기 메인날개부 내에 상기 메인로터부를 숨겨지게 하고, 상기 후측개폐부를 전진시켜 상기 후측로터부를 상기 메인날개부 후면 안으로 당기어 숨겨지게 한다.
