Swiss startup Sirius Aviation has revealed the design for its Sirius Jet, a hydrogen-electric VTOL aircraft it describes as a ‘business jet. Sirius Jet innovative aircraft combines jet aerodynamics with the flexibility of helicopters. Was developed in collaboration with BMW’s Designworks and Sauber Group.

The SiriusJet boasts a hydrogen-electric (hybrid) propulsion system with a fuel tank, enabling significantly extended flight distances. Offering a remarkable range of up to 1150 miles, it far exceeds the capabilities of fully electric eVTOLs, which typically max out at around 150 miles.

The private-use Sirius Business Jet will accommodate one pilot and up to three passengers and have an anticipated flight range of ,850 kilometers, whereas the larger Sirius Millennium Jet seats up to five passengers and can fly just over half that distance, with a range of 1,050 kilometers.

Impressive flight speed. Featuring pressurized cabin and ducted fan design solution, the SiriusJet is engineered to reach high altitudes of 30,000 feet and achieve a cruise speed of 520 km/h or 323 mph.The lift-and-cruise configuration clean-sheet design features a V-tail configuration with a series of ducted fans set into each fixed wing.

The aircraft uses liquid hydrogen as fuel and electric motors to drive ducted fans. The hydrogen is stored in cryogenic tanks inside the aircraft’s wings and fuselage and is converted into electricity by fuel cells. The electricity then powers the ducted fans, which provide thrust and lift for the aircraft.

SiriusJet is equipped with an airframe parachute system, effectively reducing the incident risk to virtually zero. This feature also significantly enhances passenger psychological comfort, especially for those apprehensive about flying, akin to Muhammad Ali who famously flew with his own parachute. We recognize the concern for passenger psychological comfort in small planes and have addressed it with this solution.
