In a groundbreaking move, Swiss aviation startup Sirius Aviation is set to redefine air travel with the unveiling of the Sirius Jet, the world's inaugural hydrogen-powered Vertical Take-Off and Landing (VTOL) aircraft. Developed in collaboration with BMW's Designworks and the Sauber Group, this cutting-edge innovation is poised to transform the aviation landscape.
The Sirius Jet comes in two variants, the Sirius Business Jet and the Sirius Millennium Jet, both powered by a revolutionary hydrogen-electric propulsion system. These zero-emission aircraft promise extended flight distances, impressive speeds, and high altitudes, all achieved at near-silent operation levels.
Sirius Business Jet:
Accommodates up to three passengers
Flight range of 1,150 miles (1,850 km)
Altitude capability of 30,000 feet
Cruise speed of 323 mph (520 km/h)
Ultra-low noise levels of 60 dBa
Sirius Millennium Jet:
Designed for commercial use, accommodating up to five passengers
Flight range of 650 miles (1,046 km)
Altitude capability of 30,000 feet
Cruise speed of 323 mph (520 km/h)
Ultra-low noise levels of 60 dBa
The heart of the Sirius Jet lies in its advanced powertrain, featuring a high energy-density hydrogen storage system. This system enables the aircraft to achieve a maximum range of 1,850 km and speeds reaching up to 520 km/h. The aircraft's distinctive ducted fan propulsion system, a result of collaboration with BMW Designworks and the Sauber Group, sets it apart from traditional VTOL designs, combining jet aerodynamics with the versatility of a plane or helicopter.
While the Sirius Jet marks a significant leap in clean aviation, challenges persist, particularly in the use of liquid hydrogen. Overcoming logistical and technological hurdles is central to its success. Sirius Aviation, driven by a team of over 100 engineers, is committed to addressing these challenges. Their ambitious timeline includes full certification by 2026, paving the way for commercial deliveries and shuttle flights by 2028.
The eagerly awaited reveal of the Sirius Jet's propulsion system is scheduled at the Payerne Airport in Switzerland on January 17. This event signifies a pivotal moment in the journey toward sustainable aviation and underscores Sirius Aviation's dedication to pushing the boundaries of innovation.
