Energy Balance Design and Analysis of Long-flight-time Solar Powered UAV

摘要

Characteristics and technical difficulties of long-flight-time solar powered UAV airborne power and energy storage system was studied, and a general design method based on energy balance relation and aerodynamic parameters was proposed. The relation formula between key parameters such as solar cell area and energy system weight ratio and aircraft platform aerodynamic parameters, battery performance and battery energy density was derived. Then the long-flight-time solar powered UAV energy system scheme was calculated with domestic mature technical parameters. This method can effectively simplify the calculation process and provide a reference for the overall design of the long-flight-time solar powered UAV platform.
