Aura Aero has acquired Voltaero, an alliance that combines AURA AERO’s industrial ambition and international reach with VOLTAERO’s expertise in hybrid-electric propulsion systems. This transaction immediately strengthens AURA AERO’s capabilities through the integration of 2,400 square metres of industrial facilities and proven hybrid-electric technologies.
The acquisition provides AURA AERO with rare experience in hybrid-electric architectures and experimental aeronautical development, including design, system integration, testing, flight operations, and data analysis. This expertise, accumulated by VOLTAERO over several years of work, finds its most concrete expression in the Cassio S, a hybrid-electric flying demonstrator. Since the start of its flight testing in 2019, it has completed 270 flights and covered approximately 25,000 kilometres under a variety of operating conditions. It therefore stands as tangible proof of technological maturity and a direct catalyst for AURA AERO’s electric and hybrid-electric developments.
Together, the companies are strengthening the French low-carbon aviation industry, accelerating the development of concrete solutions for the market, and reaffirming their ambition: to make France a global leader in sustainable aviation.
