The first aircraft with Sterna inside

Atea is an eVTOL aircraft aiming at being a low noise, low carbon alternative to helicopters, as well as enabling a brand new regional, decentralized and efficient aviation where no other transportation solution is satisfactory

A close up of an Atea model in a room

Our aircraft is performant and versatile. You can use it to replace your existing fleet with major savings in fuel consumption, operating costs and CO2 emissions.

(Our technology)

Hybrid electric propulsion
system

A modular and scalable combination of two sources of energy (fuel + battery).

A hybrid-electric aircraft is using a mix of 2 energy sources: electric batteries, used during Take-Off and Climb, to benefit from instantaneous release of high power and optimized engines that can run on Jet-A1, Sustainable Aviation Fuel or Hydrogen tomorrow, for the low energy demanding flight phases such as the cruise.

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.

Powered by
Sterna
8 Rotors
2 propellers

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.

Ground charge
air charge

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).

Where innovation
takes flight

Meeting Atea
productivity is key

Thanks to its hybrid-electric propulsion system, our aircraft offers unrivaled performance in terms of range and turnaround time. The range is 2 to 3 times greater than the competition, and turnaround time divided by 5.

Fly safe

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.

Fly far

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.

Fly quiet

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.

Fly clean

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.

You have some questions?

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.
