Weight Design of Cross-Day Solar-Powered UAV

In this paper, the development history of solar-powered UAV is briefly reviewed, and the technical characteristics and design difficulties of solar-powered UAV are analyzed. Based on the energy conversion process and the design of a solar-powered UAV, the weight design method and process of cross-day solar-powered UAV are given. In the end, some important problems in the weight design of cross-day solar-powered UAV are emphasized, including the calculation of battery weight, the design and realization of light structure and the choice of flight path, which can be used as reference for the subsequent solar-powered UAV design.
