Problems solved by technology

However, due to its large space volume and weight, it is not suitable for all UAV power supply systems
Moreover, the electrical conversion efficiency of solar electrolyzed water is very low. The hydrogen and oxygen produced by electrolyzed water need a large-area solar array to meet the needs of drones flying at night. Therefore, this system is only suitable for large drones, which limits the system. Application range

Description

technical field [0001] The invention belongs to the field of aerospace vehicle energy systems, and in particular relates to a new energy hybrid power supply system for high-altitude drones. Background technique [0002] The flight direction and power control of the UAV are flexible, and it can complete various types of survey monitoring and transportation mission requirements, and can also fly in harsh environments. At present, the biggest problem faced by drones is their own weight and power storage capacity of the power supply system. It is necessary to reduce their own weight as much as possible and increase the power storage capacity of the power supply system to meet the long-term flight requirements of drones. [0003] Traditional fossil fuel UAVs use diesel piston engines as the power system, which can meet the power requirements of high-power UAVs, and the cost is low, but the energy conversion efficiency is low, the pollution is serious and the performance is unstab...
