Aicraft DNA to improve tomorrow
Atea’s airplane aeroshape allows a greater performance in forward flight, reassures passengers and increases the overall safety levels.
Atea uses Sterna, our hybrid-electric propulsion system that combines two different energy sources:
The electric battery is mainly used for short, high-power phases such as take-off and landing.
The fuel can be conventional Jet-A1, sustainable aviation fuel and, later, hydrogen, used for cruise flights.
Atea takes off vertically in electric mode using the 8 rotors that are embedded in the wings.
Once at the appropriate altitude, the front and rear propellers - located respectively in the nose and the Vertical Tail Plane of the aircraft - are turned on to provide the aircraft with horizontal thrust.
Atea does not have any titling rotors to avoid maintenance issues and ease certification.
Atea is a plug-in hybrid-electric vehicle.
It can be recharged either on the ground(to minimize the environmental footprint)
or in the air (to maximize versatility and be capable of operating from landing sites not equipped with a charging station).
We’re taking aviation
to new heights.
The aircraft is engineered to meet the same level of safety requirements as current conventional aviation while providing an additional level of safety by ensuring the capability to continue a safe flight and landing in the event of any single failure. The mix of two energy sources in our hybrid propulsion system also provides redundancy by design to further improve the safety and operational range of the aircraft.
Our aircraft has been designed to offer a sustainable alternative to conventional aviation while maintaining the same level of performance as current aircraft. Thanks to our lift and cruise configuration with fixed-wings, Atea can fly on regional or inter-city trips for up to 2hr and over 400km.
The integration of the vertical rotors in the wings with a disruptive duct shape and powered by our hybrid-electric propulsion system brings a drastic improvement in the noise signature of our aircraft with 4 times less noise emissions than a helicopter. This noise reduction unlocks an entire new range of missions with flights closer to cities and in environments that were previously inaccessible due to noise constraints.
With our unique hybrid propulsion system using a mix of kerosene and batteries for optimized fuel consumption, it is now possible to fly cleaner with a reduction in carbon emissions up to 80%. But this is only the first step thanks to our modular architecture which is also compatible with our near future hydrogen-powered aircraft or with Sustainable Aviation Fuel to eliminate all emissions in flight.

We are talking about Regional Air Mobility, but what are the routes that Atea will fly?

How Atea, our hybrid vtol, will be used?
Atea is an innovative aircraft meant to reduce the carbon footprint of the helicopter market and provide a sustainable and practical answer to link some destinations that are still hard to reach today. But how do we plan to do that?
We have answers
Atea's main differentiation comes from our unique hybrid-electric system that gives us superior performance in terms of payload-range. The ground operations are also optimized thanks to our plug-in hybrid technology leading to quick turn-around times of less than 15min to maximize the productivity of your operations throughout the day
Atea can perform a variety of missions: passenger transportation, VIP transportation, eco-tourism, cargo transportation, medical emergency services and surveillance.
We designed Atea with operations in mind and to ease its entry into service so no specific infrastructures are required beyond what already exists. We are using conventional vertiports (which are small take-off and landing surfaces comparable to helipads).
Atea will be certified in 2027. We are currently working on the first flight of our lifesize, 1:1 flying prototype scheduled for 2024.
