Aimen Expertise Centre has accomplished the 3D printing of a cryogenic tank demonstrator for the OVERLEAF challenge. The Spanish group manufactured a 1.5-meter-diameter internal tank designed to retailer liquid hydrogen (LH2) at extraordinarily low temperatures for future plane purposes. The challenge is led by Aciturri, a Spanish aeronautics firm engaged on hydrogen storage options.
The tank design encompasses a dual-component system combining an additively manufactured thermoplastic internal vessel with an outer carbon fiber construction. The internal element maintains the liquid hydrogen at cryogenic temperatures, whereas the carbon fiber exterior offers structural integrity. Aimen utilized large-format additive manufacturing with excessive precision to create the internal tank.
“It is a technological resolution that can mark a earlier than and after within the manufacturing of parts for sustainable aviation,” stated Pablo Romero, crew chief of the Additive Manufacturing of Composites R&D group at Aimen. The manufacturing course of required over 100 hours of steady printing in a specialised robotic cell developed by Aimen. Actual-time monitoring with thermal cameras ensured high quality management all through the prolonged construct.
The manufacturing cell included high-performance 3D printing methods alongside infrared heating expertise to make sure correct adhesion between layers. This technical method was mandatory to satisfy the demanding necessities for hydrogen storage methods in aviation purposes. The tank represents a big step towards enabling hydrogen as an aviation gas supply.
Aimen collaborated with French analysis heart Canoe to develop a brand new sustainable materials for the challenge. The bio-based thermoplastic bolstered with pure fibers permits for printing robust, light-weight buildings with decreased environmental affect. This materials improvement aligns with the broader targets of making extra sustainable aviation applied sciences.
