The Spanish company ITP Aero, one of the world’s leading suppliers of aeronautical components and engines, has designed and created one of the main structures of the new Rolls-Royce UltraFan engine using 3D printing. The structure created is called TBH (Tail Bearing Housing) and is one of the joining elements between the aircraft and the engine. ITP Aero’s design and manufacturing criteria have allowed a saving of 25% of material, compared to other production processes used today.
This is a key project, as the TBH is a critical structure, capable of withstanding load conditions for all operating conditions. In addition, it houses the bearings on which the shaft that moves the front fan, the main propelling element of the engine, rests and incorporates removable acoustic attenuation panels, thus achieving a 50% reduction in the acoustic power emitted by the turbine.
3D printing, also known as additive technology, is a selective laser melting method that allows you to create components of complex geometry, using only small amounts of powder with a smaller number of tools. Among the many advantages it offers, there is a reduction in the weight of the final parts, thus achieving better aerodynamic performance and a lower environmental impact.
