The first additively manufactured integrally bladed rotor (IBR) was proudly displayed at the Farnborough International Airshow in July. The IBR is a collaboration between the Notre Dame Turbomachinery Laboratory (NDTL), Norsk Titanium (Norsk), Pratt & Whitney and TURBOCAM International as they develop and test additively manufactured turbomachinery components. This collaboration will focus on exploring the applicability of Norsk’s Rapid Plasma Deposition™ (RPD™) material to turbomachinery applications. As part of this effort, NDTL will test an additively manufactured IBR produced and inspected to meet the applicable quality specifications used in Pratt & Whitney’s current turbomachinery components. The team has completed the initial phase of testing, with TURBOCAM International conducting machining trials of Norsk’s RPD™ material and Pratt & Whitney successfully inspecting the material to the same specification as forged turbomachinery components.
