摘　　要：高空长航时无人机是未来无人机的发展方向之一。目前最具发展前景的高空长航时无人机是太阳能动力无人机。但是由于太阳光的间歇性,限制了太阳能动力无人机的续航时间。因此,为进一步延长无人机的续航时间,应用激光代替太阳光对无人机进行非接触的远程供电将是未来的研究热点。对于无人机激光远程供电系统来说能量传递的效率是影响其实际应用的重要因素之一。文中首先阐述了无人机激光远程供电系统的概念和应用背景,然后对影响无人机激光远程供电系统效率的关键因素(激光器、太阳能电池板和大气环境)进行了分析总结,并针对这些因素的影响提出了保证系统效率的方式方法。最后指出无人机激光远程供电系统要继续发展所面临的问题和挑战。The high altitude and long endurance unmanned aerial vehicle（UAV） is one of the future direc- tions of UAVs. Solar-powered UAVs have demonstrated interesting capabilities for high altitude and long endurance. However, current solar-powered UAVs are extremely light and fragile and have small payloads. The concept of UAVs with photovoltaic （PV） cells powered by a laser beam has been demon- strated and the laser beam powered UAV concept is esteemed a revolutionary technology for the high al- titude and long endurance UAVs. The concept and application backgrounds of laser powered UAVs are introduced. Meanwhile, the current situation and tendencies of lasers and PVs which are used to build a laser powered UAV are discussed. As a laser beam passes through the atmosphere, several effects com- bine to reduce the amount of energy that actually arrives at UAV. The methods for overcomeing this problem are also mentioned. Finally, the most important challenges which the laser powered UAVs will face are pointed out.
