Key technologies of solar powered unmanned air vehicle

This paper summarizes the development of solar powered unmanned air vehicles,presents some key technology in the design and manufacture process of solar powered unmanned aircraft,and then points out some technology difficulties needed to break through,including: the application research on solar cells,energy deposit systems and energy control systems,and the design of solar powered unmanned air vehicles.This solar powered unmanned air vehicle is the outcome in combination with aviation and new energy sources technology,its outputs of the aerodynamic,structural,optimal and propulsive research are deeply coupled.
