Project Description

The primary goal of this research is to develop an innovative approach to provide an improved level of thermal protection for hot-section components, such as turbine airfoils, in modern and future gas turbines. The research efforts will primarily focus on the development of integrating transpiration cooling with lattice-structure enhanced internal cooling. The proposed work will be built on proven anti-oxidation material, i.e. oxide-dispersion strengthened (ODS) alloy, and will utilize advanced additive manufacturing technologies. The utilization of ODS lattice structures near the outer surface of turbine airfoils could lay a foundation for further development of more advanced thermal protection innovation.

Project Benefits

Anticipated benefits from projects funded through the University Turbine Systems Research (UTSR) Program include development of technologies that will accelerate turbine performance, efficiency, and emissions reduction beyond the current-state-of-the-art and reduce the risk to market for novel and advanced turbine-based power generation. In addition, the UTSR Program seeks to maintain and enhance U.S. university-based turbine science capabilities to ensure a world-class scientific workforce for future generations. UTSR is a component of NETL’s Advanced Turbines Program that manages a portfolio of projects designed to remove environmental concerns over the future use of fossil fuels by developing revolutionary, near-zero-emission advanced turbines technologies.
