Abstract

Researchers are now faced with a limited flight time of the hoverable UAV due to the sluggish technological advances of the Li-Po energy density and try to find a bypassing solution for the fully autonomous hoverable UAV mission planning. Although there are several candidate solutions, automated wireless charging is the most likely and realistic candidate and we are focusing on the autolanding strategy of the hoverable UAV in this paper since it is the main technology of it. We developed a hoverable UAV flight simulator including Li-Po battery pack simulator using MATLAB/Simulink and UAV flight and battery states are analyzed. The maximum motor power measured as 1,647 W occurs during the takeoff and cell voltage decreases down to 3.39 V during the procedure. It proves that the two Li-Po battery packs having 22 Ah and connected in series forming 12S1P are appropriate for the autolanding mission planning.

Li-Po 에너지 밀도의 기술적 진보의 한계로 회전익 무인항공기의 비행시간은 제한적이기 때문에, 연구원들은 회전익 무인항공기의 완전한 자율 임무 수행을 위하여 우회 해결책을 찾고 있다. 몇 가지 후보 해결책들 중, 자동 무선 충전이 가장 가능성 있고 현실적인 후보이며, 본 논문에서는 자동 무선 충전의 주요 기술인 자동 착륙 전략에 초점을 맞추고 있다. MATLAB/Simulink를 기반으로 Li-Po 배터리팩 시뮬레이터를 포함한 회전익 무인항공기 비행 시뮬레이터를 개발하였으며, 이를 통해 비행 상태 및 배터리팩 상태를 분석하였다. 이륙할 때 1,647 W의 최대 모터 출력이 발생하였고, 이때 셀 전압은 최소 3.39 V까지 감소하였다. 이는 22 Ah를 지니고 12S1P로 연결된 2개의 배터리팩이 자동 착륙 임무수행에 적합하다는 것을 나타낸다.
