초록

최근 친환경적인 항공 추진시스템에 대한 요구가 확대되고 있는 가운데 여러 에너지원을 조합하여 장기 체공하는 무인기용 복합추진시스템을 개발하기 위한 다양한 시도가 이루어지고 있다. 본 연구에서는 주어진 임무형상에 따른 비행체의 에너지 균형 매커니즘을 최적화하기 위하여 태양전지로부터 수집 가능한 에너지와 비행체의 요구에너지 그리고 재생연료전지 구동을 통해 순환에 필요한 동력분배 관리시스템을 분석하였다.

Recently, as the needs for eco-friendly aero propulsion system increase gradually, many study works have been conducted to develop the hybrid propulsion system for High Altitude Long Endurance(HALE) UAV. In this study, we analyzed both suitable energy distribution and management methodology among the total energy collected from solar cell and the total required energy of aerial vehicle and required energy of the regenerative fuel cell(RFC) for driving in the night time and optimized the energy balance mechanism based on the ascribed mission profile.
