an ambitious design of a 5-seater aircraft with a hybrid engine

The aviation sector must also undergo its transformation to reduce its environmental footprint. Airbus or Boeing are working on planes that consume less energy, or even “zero emissions” with hydrogen. But it’s not just the big models to decarbonize!

Ascendance Flight Technologies has been working since 2018 on a vertical take-off and landing (VTOL) aircraft equipped with a hybrid propulsion system called Sterna. This allows the simultaneous use of several energy sources: electric, thermal or hydrogen, depending on the needs of future customers. The plane can be used to transport passengers of course, but also for medical emergencies, logistics or surveillance.

Multi-purpose aircraft with reduced emissions

The French start-up unveiled Atea’s first design, a 5-seater VTOL aircraft, designed to fly in peri-urban and regional areas. It provides a range of 400 kilometers, its carbon emissions are reduced by 80% and noise pollution is reduced by four. A design that shows the way forward, according to Ascendance.

Atea’s propulsion is provided by eight rotors integrated into two fixed wings and two horizontal propellers. The ducted rotor allows the aircraft to benefit from greater power during take-off and landing, this system also reduces noise emissions.

The engine is powered by a Sterna system which combines thermal and electric (a battery). Ultimately, the heat engine could be replaced by a hydrogen engine or with biofuels. The interior configuration can accommodate five travelers. The cabin, widely open to the sky, offers easy passenger access.

Atea is only a design for the moment, but it will soon exist as a full-scale prototype, assures the manufacturer. The test phases will begin in 2023, with the ambition of a presentation in 2024, at the time of the Olympic Games in Paris.
