Development of hydrogen drones in China
Development of hydrogen drones in China
๐ป At the 7th Zhejiang International Intelligent Transportation Industry Exhibition on December 11, it was announced that the Chinese Tianmu Shan-1 drone has set a world record and entered the Guinness Book of Records.
The UAV completed a non-stop flight of 188,605 km on November 16. The duration of the continuous flight was 4 hours, 17 minutes and 55 seconds.
The drone was developed by the Tianmu Laboratory at the Beijing University of Aeronautics and Astronautics. It was manufactured by Hangzhou Tianmu Hydrogen Peng Technology. The device has entered mass production. An important feature of the drone is its own hydrogen fuel system: the specific power of the fuel cell is 1500 W/kg, and the hydrogen utilization rate is 97.5%. The body is made of lightweight carbon fiber, and it has a lightweight hydrogen storage system.

Chinese developers noted that they have created a complete line of onboard hydrogen energy systems with a power range from 100 W to 40 kW, as well as a specialized flight control system and a ground station exclusively for hydrogen UAVs.


The UAV completed a non-stop flight of 188,605 km on November 16. The duration of the continuous flight was 4 hours, 17 minutes and 55 seconds. About 44900 km/hour? Earth observation satellites fly in orbits at altitudes of about 200 to 2,000 km, called low earth orbit, at a speed… Read more »
Good point. Apparently this is the less common system of using a comma instead of a dot as a decimal separator. Another source says 188.605 km, realistic for low flight. So about 44 km/hr …
Thanks AHH, that makes sense.
Don’t pat yourself on the back just yet Steve. You credited it about 1,000 times its real speed of just under 44 km/hr. There is a screenshot at 1:02 in the video which gives the real distance as 188.605 Km. I expect someone involved the story translation was using the… Read more »
Bernie, that’s why I used the question mark.
