Abstract: As a new aircraft for exploring near space, Solar powered Unmanned Aerial Vehicle (SUAV) shows new characteristics different from traditional aircraft in performance, technology, and endurance. The specific energy and specific power of SUAV occupy important positions in aircraft performance. In order to carry out an in-depth research, this paper firstly elaborates the composition and key technologies of SUAV energy system and looks forward to the future research hotspots and development trends in the diversity of energy access, the high efficiency of energy management, and the integration of energy load.

Key words: solar powered unmanned aerial vehicle, near space, energy system, energy management, wireless charging, photovoltaic antenna, artificial intelligence
