ABOVE: The world’s first hydrogen-powered VTOL aircraft, the Sirius Jet, is proposed in two variants

Swiss aviation startup Sirius Aviation (established in 2021) has revealed its hydrogen-electric vertical takeoff and landing (VTOL) aircraft, the Sirius Jet, designed in collaboration with BMW’s Designworks and Sauber Group.

The lift-and-cruise configuration clean-sheet design features a V-tail configuration with a series of ducted fans set into each fixed wing. ‘Leveraging jet aerodynamics with airplane and helicopter versatility, it achieves extended flight distances, impressive speeds, and high altitudes at near-silent levels,’ claims Sirius. The aircraft will also feature an airframe parachute system.

The aircraft will be available in two versions: the Sirius Business jet, featuring a 1,150 mile range, which is able to accommodate three passengers in comfort. The Sirius Millenium Jet, with capacity for five passengers, will possess a shorter range of 650 miles. Both will feature a pressurised cockpit and be able to cruise at around 280kts with a service ceiling of 30,000ft

On 17 January 2024, Sirius Aviation will host an unveiling event at Payerne Airport in Switzerland, featuring the first public inaugural ignition of the aircraft’s hydrogen-electric ducted fan propulsion system. The company plan to make their first flight in 2025.
