China achieved a milestone in green aviation technology this week as a 7.5-tonne unmanned cargo aircraft powered by the AEP100 – the nation's first independently developed megawatt-class hydrogen-fueled turboprop engine – completed its inaugural flight on April 4, 2026. The 16-minute test flight in Zhuzhou, Hunan Province, marks the world's first successful demonstration of hydrogen propulsion at this scale for aviation applications.
The Aero Engine Corporation of China (AECC) confirmed the engine maintained optimal performance throughout the flight, covering 36 kilometers at 220 km/h while cruising at 300 meters altitude. Engineers executed all planned maneuvers before the aircraft's safe return, validating core technical capabilities from component integration to full-system operation.
Industry analysts highlight the breakthrough as critical for developing low-altitude economy sectors, particularly unmanned logistics and island supply chains. With green hydrogen production costs declining, experts predict rapid commercialization of this technology could reshape regional air freight networks across Asia by 2028.
The achievement accelerates China's aviation decarbonization roadmap, creating synergies across hydrogen production, storage infrastructure, and advanced materials sectors. AECC representatives emphasize this innovation positions the Chinese mainland as a key player in next-generation sustainable aviation technologies.
