Transonic Research Turbine (TRT)
The Transonic Research Turbine (TRT) on the Notre Dame campus is a single stage turbine facility for research and testing of either HPT or LPT designs. The air moving equipment provides for a pressure ratio of 2.5 at 11 lbm/sec.
Like the compressor facilities, the shaft is magnetically levitated for precise rotor positioning and whirl control. The modular design allows for rapid hardware changes and extremely high build-build repeatability in aero performance, efficiency, and heat-transfer measurements. This has allowed unprecedented ability to influence advanced technology for future engine production. More than 10 test articles have been installed and tested in the last several years for industry and DOD testing.
