The objective of this study was to develop technologies for the unmanned aerial vehicle (UAV) to achieve a long endurance. The airplane was driven by electric-based propulsion systems with power supplied continuously by the endless solar energy.A design concept of a hybrid lifting configuration was proposed and design technologies for the solar-powered UAV. Unlike conventional aircrafts, this design could achieve beter aerodynamic performance, lightweight structure and guarantee large surface for using solar cells. A solarpower system was developed, and an autonomous flight system was successed in self-control and stabilization.Ground experiments were carried out to measure the performance of the solar cell, motor, propeller thrust, structure, and so on. Flight tests successfully proved the design concept and technologies of the solar plane. Results show that the new design concept and design technologies of the solar plane was encouraged to achieve a long endurance flight.
