The HERFUSE project, which stands for Hybrid Electric Regional Fuselage & Empennages, is a new, pioneering 3-year Clean Aviation research project focused on revolutionizing regional aircraft propulsion systems. HERFUSE aims to design innovative fuselages and empennages for future Hybrid-Electric Regional aircraft (HER) to reduce Green House Gases (GHG) emissions. It addresses layout, materials, components, manufacturing, and assembly challenges, integrating features for hybrid-electric propulsion and complementary systems to improve weight, durability, aerodynamics, and operations.
Recently, we published an article that highlights our close collaboration with HERWINGT and HECATE — a synergy that strengthens the structural and regulatory foundations for hybrid-electric aircraft. This collaboration focuses on optimizing airframe design, ensuring compliance with certification standards, and validating new technologies through extensive testing.
The Annual Review Meeting was a key milestone, offering us the opportunity to align on technical progress, address ongoing challenges, and define the way forward for the project’s implementation.

Additionally, we launched a new quiz series designed to foster engagement and raise awareness about the innovations we’re developing. This interactive approach helps bring our community closer to the technical details and appreciate the progress made toward a more sustainable future for aviation.
Together, these initiatives reflect the significant strides we’re making in advancing hybrid-electric technologies, demonstrating the strong collaboration, expertise, and creativity that drive HERFUSE forward.
Join our social media community on LinkedIn, YouTube, and HERFUSE official website, learn more about the project’s scope and progress, and be part of the journey as we pave the way for hybrid electric regional flies.
