摘要: 针对当前集群无人机(UAV)续航时间短, 传统高空长航时无人机任务功能不灵活, 无法适应未来复杂任务需要的问题, 提出了一种组合固定翼无人飞行器方案——空中链翼无人系统。详细梳理了二战后美国开展的有人驾驶固定翼飞机翼尖拖拽技术的探索历程, 报告了中国、美国与德国近年来翼尖连接相关技术的研究进展。采用理论研究和对比分析的方法得到了链翼在升阻比、巡航速度、续航时间、巡航高度上的优势, 进一步总结了链翼无人系统涉及的关键技术, 对空中链翼无人系统未来的发展进行了展望。

Abstract: Current cluster Unmanned Aerial Vehicles (UAVs) have the problem of short duration, and traditional high-altitude long-endurance UAVs are inflexible for both tasks and functions. They cannot meet the needs of future complex tasks. The combined fixed-wing UAV scheme--unmanned aerial system with chained wings is thus proposed. In this paper, the development process of the wingtip drag technology of manned fixed-wing aircraft in the United States after World War Ⅱ is introduced, and the research progress of the wingtip connection technology in China, the United States and Germany in recent years is reported. The advantages of chained wings in terms of lift-drag ratio, flight speed, endurance time and cruising altitude are obtained by theoretical research and comparative analysis. The key technologies involved in the chained wing unmanned system are then summarized, and future development of unmanned aerial system with chained wings is also discussed.

Key words: combined fixed-wing UAV, wingtip connection, chained wing, aerodynamic characteristics, flight performance
