This research addresses the short endurance of quadrotor UAVs by proposing an auxiliary power solution based on flexible CIGS solar patches. Through CFD simulation and photovoltaic system modeling, the layout of solar patches on the wings, fuselage, and support arms is optimized to balance aerodynamic performance and energy capture efficiency. A closed-loop methodology of "numerical simulation-wind tunnel testing-flight verification" is adopted. Results indicate that under the condition of a drag increase controlled within 5%, the solar-assisted power system can enhance UAV endurance by 15%-20%. This scheme features easy installation and low cost, providing a viable technical solution for long-endurance applications such as power inspection and logistics distribution.
