Less noise, more actions for sovereign and sustainable aviation
Powering the Future of Aviation
The future of aviation will be defined by three imperatives: performance, sovereignty and sustainability.
Around the world, civil and defence operators face growing pressure to fly farther, operate more efficiently and reduce their environmental footprint while maintaining the highest levels of operational readiness.
We believe hybrid-electric propulsion is the answer to this challenge.
By combining the reliability of thermal power with the efficiency of electrification, hybrid-electric technology unlocks a new generation of aircraft and UAV capabilities.
At Ascendance, we are building Europe's leading hybrid-electric aviation platform.
From next-generation aircraft to defence UAVs, our technologies are designed to deliver endurance, resilience and efficiency where they matter most.
One technology. Multiple applications. A new future for aviation.
Deep tech pioneers
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.
