At the 55th International Paris Air Show, Ascendance is announcing the launch of the STERNA Hybrid Pack, its proprietary hybrid-electric propulsion system. “This modular solution natively integrates a propulsion battery designed specifically for hybrid-electric aviation, an energy management system, and an electrical distribution unit,” said the company in a press release. “The system is engineered to combine performance, energy efficiency, and compliance with stringent aviation certification requirements.
“To develop this high-performance battery, Ascendance partnered with EXOES, a leading French specialist in thermal systems and batteries for mobility. This strategic partnership is based on a shared vision to accelerate the industrialization of certifiable, hybrid-electric propulsion solutions manufactured in France that meet the demanding standards of the aerospace and defense sectors.”
Ascendance is responsible for the system architecture, the Hybrid Energy Management System, onboard control and safety devices, and the Hybrid Core Unit.
EXOES contributes expertise in cell assembly, advanced thermal management, and extreme testing.
The STERNA Hybrid Pack, owned by Ascendance, “represents a major technological breakthrough. It is designed to meet the operational, economic, and environmental needs of tomorrow’s aviation. It is modular and compact and can be easily integrated into a wide range of platforms, including VLTOs like ATEA, long-range drones, light helicopters, and regional aircraft, to boost range, reduce emissions.”
