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
