38 LISI - 2024 Integrated Report Innovation Can you remind us of the origins of OPTIBLINDTM? The idea began in 2007. At that time, the LISI AEROSPACE division identified a need among major aircraft manufacturers such as Airbus, Dassault Aviation, and Boeing. They were looking for blind fastener systems for aerostructures to eliminate the need to work on both sides of the parts they wanted to assemble. The OPTIBLIND™ fastener system by LISI AEROSPACE enables such assemblies: it allows operations to be performed from one side only, without requiring access to the internal side of the structure, such as inside the wing or fuselage of an aircraft. This system makes it possible to design much more slender wings than those currently in use, resulting in improved aerodynamics. This design significantly reduces fuel consumption. The impact of this technology is as significant as engine innovations in driving the transformation of the aerospace industry. After a phase of concept evaluation, we launched a major product/process development program in 2015 to design and validate the entire range, which includes over 1,500 variants, along with associated installation tools, both portable and robotic. During this period, we also accelerated collaborations with aircraft manufacturers by integrating numerous technological demonstra- Designers are now incorporating OPTIBLINDTM fasteners into aircraft designs” tors. In 2023, we received the Supplier Innovation Award from Airbus. This was a pivotal moment for our teams — a recognition of both our innovation and the technical maturity achieved. The technology has moved from R&D into operational use. Where do things stand today? We are currently in a phase of industrial ramp-up to enable large-scale production. At the same time, designers of future aircraft now recognize that this technology is mature and are already incorporating it into the designs of nextgeneration aircraft. In parallel, we are expanding the product range with additional versions to meet new demands from aircraft manufacturers, while focusing our research and development efforts on new technologies. Today, we are adding sensors, connectivity, and intelligence to the installation tools for the fasteners, integrating a control function. Operators will have real-time access to data that indicates whether the assembly is correct or if an issue has occurred. We are advancing our research and are now capable of integrating digital solutions and artificial intelligence into the high performance and reliability of our products. #AEROSPACE #TECHNOLOGICAL DISRUPTION Interview Benoit Regnard R&D and Customer Applications Director LISI AEROSPACE Outlook
