多旋翼无人机动力系统的实现形式研究

Analysis on the implementation form of multi-rotor UAV power system

多旋翼无人机因其比传统飞行器体积小、操控简单、飞行成本低等优点,已经被广泛应用于影视航拍、新闻媒体、交通管理、飞行表演、农业植保、电力巡线、测绘等领域。文章主要介绍了多旋翼无人机动力系统的几种实现形式,通过内燃机、锂电池、燃料电池锂电池混合动力3种驱动形式的动力系统示意图分别简述其工作原理和优缺点。

Multi-rotor UAV has been widely used in film and television aerial photography, news media, traffic management, flight performance, agricultural plant protection, power line inspection, surveying, etc. field because of its small size, simple control and low flight cost. This paper mainly introduces several implementation forms of the multi-rotor UAV’s power system. The working principle, advantages and disadvantages of the three-drive power system of internal combustion engine, lithium battery and fuel cell lithium battery are briefly described.
