Multi-Objective Optimization Design and Flight Test of A Solar-Powered Unmanned Aerial Vehicle

这项研究的目的是发展无人驾驶飞行器（UAV）的技术，以实现长续航力。飞机由电力推进系统驱动，并由无穷无尽的太阳能持续提供动力。提出了一种混合升力构型的设计思路和太阳能无人机的设计技术。与传统飞机不同，这种设计可以实现更好的空气动力学性能，轻量化结构，并保证使用太阳能电池的大表面。研制了太阳能发电系统，实现了自主飞行系统的自我控制和稳定。地面试验对太阳能电池、发动机、螺旋桨推力、结构等性能进行了测试。飞行试验成功地验证了太阳能飞机的设计理念和技术。结果表明，采用新的设计理念和设计技术，可以实现太阳能飞机的长航时飞行。

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.
