Dalian University of Technology has developed a low-altitude, long-endurance, over-sea hybrid-wing drone “Dalian No.1″. The drone has met all key performance targets, including payload capacity, range and flight time, and wind resistance. It is expected to provide China with a high-performance operational platform for establishing an integrated low-altitude economy ecosystem across land, sea, and air.

“Dalian No.1” combines the vertical takeoff and landing capability of a helicopter with the high-speed cruising ability of a fixed-wing aircraft. Its maximum takeoff weight exceeds 150 kg, with a payload of 45 kg, a wingspan of 6.5 meters, and a cruising speed of 110 km/h. In terms of technical innovation, it features a biomimetic design inspired by seagull wings and a streamlined curved design, giving it high recognition as an aircraft for marine applications. The main wing, with its dihedral angle and optimized load distribution along the wingspan, greatly improves wind resistance and lateral stability. Additionally, integrating materials and structure reduced the aircraft’s weight by over 15%, and the gasoline-electric hybrid technology enables long-distance flights over the sea exceeding 1,300 kilometers. The drone can vertically take off and land in wind speeds of 10.8–13.8 m/s and maintain stable cruising in wind speeds of 13.9–17.1 m/s, making it highly adaptable for various maritime operations such as sea patrols, cargo transport, and emergency rescue.
