Founded by Alexey Popov in 2021, Sirius Aviation AG is headquartered in Baar, Zug, Switzerland. Popov is the CEO of Sirius Aviation. The company is in the business of making clean, safe, economic, quiet, long-range and fast hybrid-electric vertical takeoff and landing (VTOL) passenger jets for advanced air mobility (AAM), capable of both city-wide and regional travel. The company is developing state of the art hydrogen-powered hybrid-electric VTOL jets in collaboration with BMW Designworks and the Sauber Group. (Image credit: Sirius Aircraft)

Sirius eVTOL Jet passenger defunct concept design aircraft
The Sirius eVTOL Jet is a long-range passenger electric vertical takeoff and landing (eVTOL) defunct concept design business jet. The graphic above of the company's first concept design jet was published on the company's Facebook Page on October 25, 2021. At the time, the company wrote their "Sirius Jet" used eVTOL technology that is "100% electric with zero emissions in the atmosphere." The aircraft holds one pilot and possibly four or more passengers.

In 2021, the company did not reveal any of the specifications for the jet. However, one Facebook post said their aircraft would fly from Zurich to Geneva (Switzerland) in 45 minutes, revealing their predicted cruise speed was 299 km/h (186 mph). The aircraft has a front canard wing and one high main wing towards the rear of the aircraft and all wings have winglets. The are a total of 24 electric ducted fans (EDFs) on the aircraft with a total of 24 electric motors. Each canard wing has four electric ducted fans and the canard wing is a tilt-wing. On the rear of each side of the high main wing, there are eight electric ducted fans which rotate back to vertical for VTOL flight. The high main wing is a fixed-wing. The aircraft was planned to be powered by battery packs.

The fuselage is made from carbon fiber composite for a high strength to low weight ratio. The jet has no tail. The aircraft has retractable tricycle wheeled landing gear. There is a whole aircraft emergency ballistic parachute on the aircraft. The company at the time, estimated the aircraft's noise would be less than 60 dB at a 100 meters (328 feet) distance.

In 2021, the company's website stated they expected the Sirius eVTOL Jet to be produced by 2025. The Sirius eVTOL Jet concept design has been scrapped and is now defunct. In December 2023, the company stated the first flight of the full-scale Sirius Business Jet demonstrator is planned for 2025.

Specifications:

  • Aircraft type: Long-range eVTOL concept design jet aircraft
  • Piloting: 1 pilot
  • Capacity: Unknown (possibly 4 passengers)
  • Cruise speed: 299 km/h (186 mph)
  • Propellers: 24 electric ducted fans (EDFs)
  • Electric motors: 24 electric motors
  • Power source: Battery packs
  • Noise: <60 dB at a 100 meters (328 ft) distance
  • Fuselage: Carbon fiber composite
  • Windows: Larger than conventional business jet windows
  • Wings: 1 canard wing with winglets and 1 main high wing with winglets
  • Landing gear: Retractable tricycle wheeled landing gear
  • Safety features: Distributed Electric Propulsion (DEP), provides safety through redundancy for its passengers and/or cargo. DEP means having multiple propellers (or ducted fans) and motors on the aircraft so if one or more propellers (ducted fans) or motors fail, the other working propellers (or ducted fans) and motors can safely land the aircraft. There are also redundancies of critical components in the sub-systems of the aircraft. There is a whole aircraft emergency ballistic parachute.
