초록

오늘날 무인기는 기술 발전을 통해 육해상의 다양한 분야에서 이용되고 있다. 한국항공우주연구원(KARI)에서는 육상용 수직이착륙기로 개발된 틸트로터 무인기를 해상에서 운용할 수 있도록 임무영역 확장을 고려하고 있다. 틸트로터 무인기의 효과적인 해상운용을 위해서는 함상이착륙이 필요하지만 해상은 지상에 비해 염분, 연무, 바람등 기상영향을 많이 받는다. 또한 지상과는 달리 선박 운동으로 인한 착륙지점의 운동이 발생하며, 자동 함상착륙을 어렵게 만든다. 이러한 무인기 함상이착륙을 위하여 본 논문에서는 파고에 따른 선박 운동을 모델링 하고, 무인기 시뮬레이터를 통해 시험평가한 결과를 제시하고 있다.

The mission of UAV has been expanded from a land to an ocean based on an enhancement of its technologies. Korea Aerospace Research Institute (KARI) also tries to expand the mission of tilt rotor UAV to an ocean, in which the shipboard landing of UAV is required. However the environment of an oceanic operation is severer than that of land due to salty, fogy, and windy condition. The landing point for automatic landing is not fixed due to movement of shipboard in roll, pitch, and heave. It makes the oceanic operation and landing of UAV difficult. In order to conduct an oceanic operation of tilt rotor UAV, this paper presents that the sea wave modeling according to the sea state is conducted and the shipboard landing of tilt rotor UAV under the sea wave is tested and evaluated through the flight simulator for UAV.
