Ascendance just announced it has selected ENGINeUS, the first EASA-certified electric motor,
developed by Safran Electrical & Power, for the prototype flying ATEA, its hybrid-electric vertical
take-off and landing (VTOL) aircraft.
ATEA, which features an innovative propulsion architecture consisting of eight vertical electric motors
and two horizontal electric motors, is a silent low-carbon alternative to conventional helicopters,
designed to reduce environmental impact and pave the way for more efficient regional connections.
The flying ATEA demonstrator, currently in production, will be equipped with two ENGINeUS electric
motors built by Safran Electrical & Power, providing horizontal propulsion and each developing in
excess of 100kW. With its power and control electronics integrated directly into the motor and its
optimized air cooling system, ENGINeUS meets ATEA’s requirements.
Ascendance began its ground testing campaign at its representative aircraft test facilities, in Muret,
south of Toulouse, France. The purpose of these tests is to approve the integration of new
technologies, including ENGINeUS, into ATEA’s hybrid electric propulsion system, and validate their
performance.
“Safety is central to our program, particularly the first of our test flights to be conducted with a pilot on
board. This collaboration with Safran Electrical & Power, a leading industry player, is an opportunity for
us to benefit from their expertise in performance and safety, as well as the performance of the
ENGINeUS motors”, says Jean-Christophe Lambert, Ascendance’s CEO.
“We are very proud to support Ascendance with their ambitious VTOL ATEA program. This
announcement, which comes after the EASA certification of our ENGINeUS motor, consolidates our
position as a pioneer in the field of electric propulsion. It is the result of several months of technical
collaboration between our two companies in the Occitanie French region”, said Agnès Pronost-Gilles,
Executive Vice President and General Manager of Power Division, Safran Electrical & Power.
The ATEA project was selected in 2023 within the framework of the France 2030 recovery plan, as
part of the “Produce a low-carbon aircraft in France” program. As such, Ascendance relies on a
number of French players for the aircraft’s key systems
