On March 27, 2025, the history of aviation crossed a new stage with the first flight of a helicopter powered by hydrogen. Moreover, This ambitious project was led by Unith Bioelectronics. Furthermore, a subsidiary of United Therapeutics Corporation, which managed to take off a modified Robinson R44 in Bromont, Quebec. Nevertheless, Thanks to Transport Canada, the device has received certification for an experimental flight. In addition, Although the flight lasted “it flies without drop kerosene”: less than four minutes, it has demonstrated significant technical prowess. Moreover, A step forward that could mark a turning point in green aviation.
The secrets of hydrogen propulsion – "it flies without drop kerosene":
Unith Bioelectronics has integrated advanced technology to propel the helicopter. Furthermore, The system combines two hydrogen batteries with proton exchange membrane (PEM), coupled with a small battery pack. For example, This configuration ensures an effective response to the fluctuating energy needs of the device. According to reports, around 90 % of the energy used came from hydrogen, demonstrating the viability of this energy solution. The success of the flight valids PEM technology. proving its ability to meet the rigorous requirements of takeoff and vertical landing.
“This accelerated nuclear test clearly targets China”: the United States goes up a gear
This innovation is part of the Project Proticity. a collaboration between Unith Bioelectronics and Robinson Helicopter. The objective is ambitious: to develop a new generation of zero emission helicopters. These devices could in particular be used for transporting organs. a mission directly linked to the medical activities of Unith Bioelectronics.
An unsuspected wealth under the Alps: immense reserves of clean fuel could change the energetic situation
A step towards more efficient helicopters – "it flies without drop kerosene":
The next test phase provides for. the integration of a liquid hydrogen storage system. This technological choice is strategic. because liquid hydrogen is energetically denser than its gas form, thus promising increased autonomy to helicopters. An advance that could revolutionize the scope and efficiency of hydrogen flights.
The current tests could open the way to a wider adoption of hydrogen in the aviation sector. While the world strives to reduce carbon emissions, hydrogen helicopters represent a promising solution. This first flight is only the beginning of a series of developments that could transform the aeronautical landscape.
