无人机动力技术发展现状与展望

无人机是近几年快速发展起来的一种高新技术。由于其拥有安全性高、效率高、成本低的优点,迅速在电力线巡检、海岛监测、森林防火、石油管道巡检等行业替代传统巡检、监测技术,形成常态化运营。但续航时间一直是阻碍无人机系统广泛应用的主要因素,本文探讨了现阶段无人机的动力技术,包括锂离子电池、氢燃料电池、太阳能电池、和活塞式航空发动机等动力技术的使用现状,并对未来发展趋势进行展望。

UAV is a new technology developed rapidly in recent years. Because of its high safety, high efficiency and low cost, it is rapidly replacing traditional inspection and monitoring technology in power line inspection, island monitoring, forest fire prevention, oil pipeline inspection and other industries to form normalization operations. However, the endurance time is the main factor that hinders the wide application of UAV system. This paper discusses the power technology of UAV at present, including the use of lithium-ion battery, hydrogen fuel cell, solar cell, piston aero engine and other power technology, and prospects the future development trend.
