System for Additive Manufacturing of Gas Turbine Engine Hot-Section Components
Abstract
System for Additive Manufacturing of Gas Turbine Engine Hot-Section Components Dr. Richard Fonda, Manufacturing Science, ONR Code 03T Abstract This DURIP proposal requests funds for the acquisition of a custom-built system to advance the maturation of scanning laser epitaxy (SLE) technology for additive manufacturing of turbine engine hot-section components. SLE is a metal powder bed-based laser additive manufacturing technology developed at Georgia Tech under ONR sponsored programs specifically for repair and production of turbine engine hot-section components directly from powders. Basic research activity on SLE is presently supported by ONR grant N0014-14-1-0658 titled “Cyber-Enabled Direct Digital Laser Manufacturing of Turbine Engine Hot-Section Components” awarded under ONR BAA 14-004 “Cyber-Enabled Manufacturing Systems for Direct Digital Manufacturing” (Program Sponsor Dr. Richard Fonda, ONR Code 03T). The proposed DURIP project directly supports the objective of ONR’s Cyber-Enabled Manufacturing Systems for Direct Digital Manufacturing (CeMS-DDM) program, which is to develop the models and tools necessary to enable prediction and control of additive manufacturing processes, anticipating defect formation and initiating corrective actions during manufacture in real-time. The overall objective of this DURIP project is to acquire and build an advanced SLE additive manufacturing system to support the advancement of ongoing research under ONR grant N0014-14-1-0658. This new system will provide unique research instrumentation capability worldwide for the processing of powders of so-called “non-weldable” alloys to produce turbine hot-section components. This capability is critically needed for advancing US national interests in the maturation of US-made production-capable additive manufacturing systems, and for leapfrogging over advances made in Europe over the past decade. Students and postdocs will contribute to the design and construction of this state-of-the-art system. Upon its commissioning, they will utilize this system for conducting cutting-edge research in metal additive manufacturing. Thus, this system will greatly benefit future research, education, training and commercialization activities in CeMS-DDM at Georgia Tech for at least the next decade.
