World leader in helicopter turbines, Turbomeca has announced that he would now produce some parts of its new gas turbine Arrano using 3D metal printing.
From the TM 800 demonstrator, this engine should introduce a fuel consumption lower by 10 to 15% to these competitors. It is he who will equip the X 4, the next helicopter of Eurocopter. To achieve this ambitious promise, its designers are using 3D printing.
Parts in 3D printing, a first at Turbomeca
The specialist of turboshaft engines for helicopter will produce the fuel injectors of this all-new engine, as well as the tourbillonneurs of the combustion chamber of the Ardiden 3, an engine selected by Hindustan Aeronautics Ltd. for its twin-engine Dhruv, by the Russians for the Ka-62 and the Chinese for its ac532.
Turbomeca will therefore have recourse to printing by Selective Fusion by Laser (SLM) to produce prototype parts either, but the coins of series. The french installed an EOS printer on its site in Bordes, in the Southwest. The release of industrialist emphasizes that a fuel injector classic consists of a dozen different pieces. Thanks to 3D printing, Turbomeca produced this injector with a one-piece, integrating functions of cooling and injection advanced.
Implementing 3D in Bordes printing is one of the elements of its programme ‘Line of the future’. It includes the installation of machine tools high-end, 3D printers and method as the additive manufacturing and processes such as HVOF (Projection by flame supersonic) coatings to produce compressors and blades on the site.
