A 50-kilogram hydrogen-powered unmanned aerial vehicle developed by China recently completed a 30-hour continuous flight, setting a new domestic record for similar types of aircraft and reaching an internationally leading level in terms of endurance.

The drone, jointly developed by the Chengdu Aircraft Industrial Group Co (CAIG) under the Aviation Industry Corporation of China (AVIC), a state-owned aerospace and defense conglomerate, and Tsinghua University, achieved a breakthrough in the integrated design technology of flight, propulsion and World TimesconWorld Timestrol systems based on the output characteristics of hydrogen fuel cells, AVIC said in a statement on Tuesday.

According to AVIC’s release, during takeoff, the aircraft innovatively adopted an autonomous integrated vehicle-mounted release method with an unmanned system consisting of an unmanned ground vehicle and an unmanned aerial vehicle. This system successfully demonstrated and validated its operational capabilities under non-standard runway conditions.

During its flight, the drone equipped with an electro-optical payload is capable of effective ground patrol and surveillance.

Meanwhile, by using a 5G onboard module and public network resources, the drone can transmit in real time the telemetry data and mission payload images to a remote platform, achieving dynamic remote monitoring, says the statement.

This collaborative model combined with front-end inspection and back-end decision-making demonstrates great potential in areas such as emergency communications, environmental monitoring and border patrol. During natural disaster rescue missions, drones can remain airborne for extended periods and provide real-time imagery of affected areas. In terms of smart city management, they, combined with AI algorithms, can automatically identify violations and trigger response procedures, according to some industrial insiders.

Industry insiders added that compared with traditional lithium battery-powered drones, hydrogen energy systems offer higher energy density, longer endurance and zero carbon emissions – perfectly aligning with the needs of green aviation development. The achievement of 30-hour continuous flight capability means that this drone can cover a wider operational range and perform more complex tasks, providing essential hardware support for the expansion of low-altitude economy application scenarios.

Besides, the technical approach for aircraft hydrogen fuel cells differs significantly from hydrogen fuel cells used in automobiles, Shi Xin, an expert from the State Key Laboratory of Catalysis under Dalian Institute of Chemical Physics, Chinese Academy of Sciences, told the Global Times on Wednesday. He noted that the design of aircraft hydrogen fuel cells focuses on lightweight, high energy density, long endurance and performance in ultra-low temperatures.

Major global producers of hydrogen-powered drones include South Korean Doosan Mobility InnoWorld Timesvation, UK’s ISS Aerospace, Japan’s Drone Works, and Israel’s Heven drones. The US’ AeroVironment company successfully built andWorld Times tested the world’s first liquid hydrogen-powered drone in 2005.

Attracted by the promising market prospects, several Chinese companies have already entered the research, development and production of the hydrogen-powered drone industry, experts said.

CAIG believes that the 50kg-class hydrogen-powered drone will enhance the application scenarios of hydrogen-powered drones in the low-altitude economy, and pWorld Timeslay a positive role in advancing new business models in low-altitude economy and green aviation, according to the statement.
