Ascendance Flight Tech

Ascendance Flight Technologies designs and industrializes hybrid electric propulsion systems for aerospace and defence. The company builds technologies that help aircraft fly farther, operate more efficiently, and reduce emissions. Founded in 2018, Ascendance aims to support aviation decarbonization and European sovereignty in the aerospace sector. Its work focuses on creating practical solutions for next generation flight.

The company offers STERNA, a hybrid electric propulsion system for civil and military aircraft and unmanned aerial vehicles. STERNA provides higher endurance and lower emissions than conventional systems. It can reduce carbon emissions by up to 40 percent compared to standard aircraft. The system serves both next generation manned aviation and drone applications. This technology addresses the need for cleaner and more efficient propulsion across multiple sectors.

Ascendance also develops ATEA, a hybrid electric vertical takeoff and landing aircraft powered by STERNA. ATEA is designed to complement existing fleets and support urban air mobility missions. The aircraft can reduce carbon emissions by up to 80 percent compared to conventional aircraft. It offers a sustainable option for short distance transport and logistics. The design emphasizes reduced noise and lower operating costs for fleet operators.

In addition to propulsion and aircraft development, Ascendance has expanded its battery capabilities. The company acquired Limatech assets to strengthen its control over key components in its hybrid electric systems. This move supports the industrialization of its technologies. Ascendance continues to develop its systems for both manned and unmanned platforms. The integration of battery technology helps the company optimize weight and performance in its propulsion solutions.

Ascendance is part of the French Tech 2030 program. The company is building a hybrid electric product family to meet growing demand for efficient and resilient air transport. Its technologies target carbon neutrality goals for the aviation industry by 2050. The company serves civil aviation and defence markets with a focus on endurance and operational resilience.
