HALE 무인기의 태양전지 열특성에 관한 해석적 연구

HALE(High Altitude Long Endurance) UAV needs enough energy for long endurance in high altitude. It generally uses energy source such as solar energy, rechargeable batteries. Temperature plays an important role to determine both power output and electrical efficiency of solar arrays. Performance of Solar cell commonly is enhanced by decreasing module temperature. Therefore, it is anticipated that efficiency and power of solar arrays in high altitude field are more than ground. For predicting thermal characteristics of solar arrays, conjugate heat transfer analysis is performed with solar arrays on main wing. This result provides guidance for designing energy balance and flight profile of HALE UAV.
