First additively manufactured integrally bladed rotor displayed at the Farnborough International Airshow

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. …

10MW Test Cell Inlet Installation

The 10MW test cell at the Notre Dame Turbomachinery Laboratory (NDTL) is nearing completion with the installation of an inlet. The inlet has been designed for compressor testing with a mass flow on the order of 100 lbm/s. Aerodynamic design and flow conditioning have been supported by using CFD tools in order to guarantee uniform flow at the compressor inlet and low pressure losses in the operating range. The low loss design makes it possible to reach low compressor pressure ratios in choked conditions.…

Notre Dame Turbomachinery Laboratory collaborates with Williams International to support jet engine testing

The Notre Dame Turbomachinery Laboratory (NDTL) at the University of Notre Dame has entered into an 11-month agreement with Williams International (WI) to support jet engine testing using advanced instrumentation methods developed by NDTL researchers. Engine testing will occur in two phases with the first phase to begin in January 2018 at the WI campus in Michigan. After the test, NDTL will have supported its first full scale jet engine test.
