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.
