During the 7th Zhejiang International Smart Transportation Industry Expo, an official adjudicator from Guinness World Records made a momentous announcement. The mass - produced "Tianmushan - 1" UAV had etched its name in the record books by setting the world record for the "longest distance flight by a multi - rotor UAV powered by a hydrogen fuel cell."

On November 16, 2025, this remarkable UAV took to the skies over the Hangzhou International Campus of Beihang University. It soared non - stop for an impressive 188.605 kilometers, completing the journey in 4 hours, 17 minutes, and 55 seconds. The "Tianmushan - 1" is a hydrogen - fueled multi - rotor UAV. It had its maiden flight in August 2024 and subsequently entered mass production in April 2025.

This UAV is specifically designed for long - endurance low - altitude missions. One of its standout features is its ultra - long endurance capacity. Without carrying any payload, it can stay airborne for up to 240 minutes. The Tianmushan Laboratory, which was established in June 2022 and is overseen by Beihang University, is situated at the Hangzhou International Campus of Beihang University.
