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 Hybrid-Electric VTOL Jet passenger defunct concept design aircraft
The Sirius Hybrid-Electric VTOL Jet is a long-range passenger hybrid-electric VTOL defunct concept design business jet. The concept design aircraft holds one pilot and possibly four or more passengers. 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 planned on an all-electric Sirius Jet and a hybrid-electric Sirius Jet and both jets would have zero emissions in the atmosphere.
In 2021, the company did not reveal any of the specifications for the Sirius Hybrid-Electric VTOL Jet. However, one Facebook post said their aircraft would fly from Zurich to Geneva (Switzerland) in 45 minutes, revealing the jet’s predicted cruise speed would be 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. There 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 is a tilt-wing. On 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 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 noise would be less than 60 dB at a 100 meters (328 feet) distance.
In 2021, the company’s website expected the the Sirius Hydrogen-Electric VTOL Jet to be produced by 2027. The Sirius Hydrogen-Electric VTOL 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 hydrogen-electric VTOL concept design jet aircraft
- Piloting: 1 pilot
- Capacity: Unknown
- Cruise speed: 299 km/h (186 mph)
- Range: 800 km (497 miles)
- 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.
