基于油电混合动力技术在无人机中的应用

Application of Hybrid Electric Technology in UAV

目前无人机动力多以纯电动机或者纯燃油发动机为主,纯电动无人机易操控,稳定性高,但是续航里程较差,而纯燃油发动机可以轻松解决续航问题,但发动机对空气中氧浓度要求高,且控制响应灵敏性能较差,很难准确控制和协调驱动旋翼的桨距、转速等,不能有效的保证无人机稳定飞行,高空高速及精确定位的性能。本文通过分析油电驱动的产生、前景、驱动形式、优缺点等,为油电混合动力技术应用于无人机动力系统中提供参考方案。

At present,the power of UAV is mainly pure electric motor or pure fuel engine.Pure electric UAV is easy to operate and has high stability,But its endurance mileage is poor.Pure fuel engine can easily solve the endurance problem,But the engine has high requirements for oxygen concentration in the air and poor control response sensitivity,So it is difficult to accurately control and coordinate the pitch and speed of driving rotor,It can not effectively ensure the stable flight,High altitude,high speed and accurate positioning performance of UAV.By analyzing the generation,prospect,driving form,advantages and disadvantages of oil electric drive,this paper provides a reference scheme for the application of oil electric hybrid technology in UAV power system.
