China’s Tianmushan №1: World’s First 100-Kilometer Hydrogen Drone

China’s Tianmushan N-1 drone successfully completed its inaugural flight on August 26th, marking a significant leap forward in unmanned aerial vehicle (UAV) technology. This drone is a global pioneer, boasting a remarkable 100-kilometer flight range, powered by hydrogen fuel cells, and featuring a multi-rotor design.

Developed by a research team at the Tianmushan Laboratory, the drone’s body is constructed from durable and lightweight carbon fiber. The hydrogen fuel cell system and carbon fiber hydrogen storage vessels were also developed in-house, delivering an energy density exceeding 1000 watt-hours per kilogram — approximately four times that of standard lithium batteries.

With a flight time of 4 hours and an unprecedented range of 100 kilometers, the drone weighs 19 kilograms when empty and can carry a maximum payload of 6 kilograms. For added safety, it is equipped with a parachute that automatically deploys in case of malfunctions, reducing the risk of crashes and potential damage to the surrounding environment.

These exceptional specifications make the drone suitable for a wide range of applications, including aerial photography, environmental monitoring, and search and rescue operations. It can also be used for delivering goods to relatively distant locations.

The drone can operate in harsh environmental conditions, such as extreme cold, which can pose challenges for some electric aircraft. It has been tested in frigid regions at temperatures as low as -40 degrees Celsius.

This advanced drone reinforces the promising future of hydrogen fuel in low-altitude aviation. It also expands China’s fleet of unmanned aerial vehicles, offering greater flexibility and efficiency in operations by providing a wider range of options tailored to specific mission requirements.
