How far can a hydrogen-powered drone really fly? That question came to life at Beihang University’s Hangzhou International Campus as the long-range UAV “Tianmushan-1” made its public debut. Government officials, university leaders, and research teams gathered for the maiden flight ceremony, touring advanced laboratories and witnessing firsthand how cutting-edge aviation research is taking shape in Zhejiang Province.
On November 16, 2025, “Tianmushan-1” completed a non-stop flight of 188.605 kilometers in 4 hours, 17 minutes, and 55 seconds without landing. The mission was monitored in real time and later subjected to strict verification, with all data meeting Guinness World Records requirements. Its hydrogen power system remained stable throughout the flight, demonstrating reliable handling and strong technical performance, and the achievement was officially certified as the world record for “Longest distance flight of a hydrogen-powered multirotor/drone.”
Developed by the Tianmushan Laboratory, “Tianmushan-1” is a 100-kilometer-class hydrogen-powered multirotor UAV designed for long-endurance missions. The project highlights the advantages of hydrogen energy in extending flight time while reducing environmental impact. Researchers say the breakthrough opens new possibilities for applications such as long-range inspection, environmental monitoring, and emergency response, while also injecting fresh momentum into the development of advanced aviation technology in Zhejiang Province.
