for cleaner aviation


The future of Vertical Mobility


Atea is a vertical take-off and landing aircraft (VTOL) designed as a clean, quiet and efficient advanced air mobility solution.

With a range of 400km+ and a turn-around time of only 10min thanks to our unique hybrid propulsion system, our aircraft meets the operational requirements of aerial mobility providers today for a wide range of missions such as passenger transportation, Emergency Medical Services, sightseeing, or Surveillance and Patrol.

The entire aircraft has been designed in compliance with the requirements of EASA SC-VTOL regulations and their associated Means of Compliance on the vehicle end. The aircraft also meets current operational requirements under Air Ops Regulation on flight routes and flight reserves.


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.

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 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 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.



We are leveraging Sterna, our unique modular hybrid propulsion technology to unlock today’s and tomorrow’s viable cleaner aviation solutions. We are continuously working to provide the technologies and technical support to empower aircraft manufacturers to reduce the environmental impact of their future aircraft generations.


Vertical Take-Off and Landing aircrafts are just the first use case to benefit from our patent-pending hybrid propulsion system. The entire system architecture can be scaled up to answer the future requirements of regional aviation and propel aviation into a new, sustainable era.


Our hybrid propulsion system brings a drastic reduction in carbon and noise emissions for a cleaner sky today and tomorrow. Sterna is the key enabling technology and the cornerstone of future cleaner aviation.

Engineered for safety & efficiency

Our hybrid propulsion system is engineered to match the requirements of future Distributed Propulsion systems and embeds the required algorithms to control the multiplicated number of propellers ensuring efficient, safe flight.

Energy transition ready

Our modular architecture can be adapted to new generation aircrafts with a wide array of energy sources from kerosene, biofuels, synthetic fuels and ultimately hydrogen fuel cells.

Long range & high endurance

The combination of different energy sources as well as the top-grade energy management algorithms ensure optimal performance  both in flight (cruise time, cruise speed) and on the ground. Our technology ensures a fit with existing infrastructures and limited turn-around times.

Intelligence embedded

The hybrid propulsion system is an unprecedented concentration of embedded intelligence from energy management to flight controls including a complete set of data from the motors, batteries etc. that will significantly simplify maintenance operations and improve aircraft availability and customer services.
