Energy System Simulation for Low-Altitude Solar-Powered UAVs

Due to the special energy type of solar aircraft, the endurance capability of the long-haul aircraft type is very prominent. However, the solar vehicle energy system has a significant impact on performance. This paper studies the energy system design optimization and system simulation of low-altitude solar aircraft. Firstly, an optimization method for low-altitude long-endurance UAV energy system is proposed, which fully considers the influence of date and environmental factors on energy harvesting and consumption of solar aircraft. Secondly, according to the energy optimization method, the UAV energy system is optimized, and the simulation results verify the ability and reliability of the UAV’s continuous long-haul flight.
