Title: Internally Cooled Turbine Rotor for Small Gas Turbine

Abstract

In collaboration with Brayton Energy LLC, ORNL worked to develop the necessary processing science for the high-gamma prime Ni-base superalloy CM247 for advanced small turbine applications. Preliminary monotonic testing indicated the behavior of electron beam melted (EBM) CM247 achieved similar properties of the cast counterpart. Brayton has applied these results to both radial and small axial turbine rotor designs. Preliminary results indicate that measurable increases in turbine inlet temperature may be achieved while respecting aerodynamic constraints.
