A new hybrid-electric rotorcraft drone, comprising key components designed in Ningbo, has successfully completed its maiden flight, marking a significant step forward in China's efforts to integrate next-generation propulsion systems into unmanned aerial vehicles.

The drone features a turbine-based hybrid-electric propulsion system jointly developed by Beihang University, its Ningbo innovation research institute, and Swiwin Turbojet Equipment Co.

The system combines high-power turbine generation with efficient electric rotors, addressing limitations of conventional battery-powered drones, which often struggle with short flight times and limited payloads.

The development team spent two years overcoming technical challenges, including optimizing generator performance, controlling high-speed rotor vibrations, and implementing a new oil-gas hybrid cooling system. They also developed a coordination strategy for multiple power units running in parallel, reducing the complexity of flight system management.

Associate Researcher Wei Xiaocheng, project lead, said the maiden flight is just the first step. The team will continue to refine fuel efficiency, heat management, and platform integration. With greater endurance, increased payload capacity, and reliable operation in challenging conditions, the hybrid-electric system is expected to support logistics, inspection, and emergency response, contributing to China's emerging low-altitude aviation sector.
