Swiss aviation startup SIRIUS AVIATION AG has unveiled the revolutionary Sirius Jet – the world’s first hydrogen-powered Vertical Take-Off and Landing (VTOL) aircraft. The aircraft has been designed in collaboration with Designworks, A BMW Group Company and Sauber Group.
The Sirius Jet is a high-performance, zero-emission VTOL aircraft propelled by a hydrogen-electric propulsion system. Leveraging jet aerodynamics with airplane and helicopter versatility, it achieves extended flight distances, impressive speeds, and high altitudes at near-silent levels. This is a significant achievement in aviation and demonstrates the company’s commitment to innovation, sustainability, and safety.
Sirius Aviation AG, which has a team comprised of over 100 engineers, has been working hard on intense R&D to develop this project in the beautiful lakeside town of Baar since 2021. According to their claims, they have already started the certification process with the FAA and scheduled the first demonstration plane flights in 2025. They plan to achieve full certification, commercial deliveries, and shuttle flights by 2028.
The project is essentially a smaller version of Germany’s Lilium Jet, but it runs on #hydrogen for higher-density energy storage and a much longer range. The propulsion system is also different, as it uses deflected thrust from its banks of fans instead of just tilting the propulsion units the way Lilium does.
While gaseous hydrogen may be used for short-haul aircraft, Sirius is working on using #liquid hydrogen (#LH2) for longer-range flights. However, liquid hydrogen needs to be kept incredibly cold throughout distribution, filling, and flight. Even though gaseous hydrogen aviation is still cutting-edge, liquid hydrogen for aviation is even less mature as a technology. It was only last September that H2FLY made the world’s first piloted flight of a liquid H2-powered plane.
