The Allison Gas Turbine Division of General Motors Corporation (GMC) completed the Advanced Gas Turbine Technology Project under contract to the National Aeronautics and Space Administration (NASA) Lewis Research Center (LeRC) using funding received from the Heat Engine Propulsion Division, Office of Transportation Systems in the Conservation and Renewable Energy Group of the Department of Energy (DOE) in the summer of 1987. This advanced, high risk work was initiated in the fall of 1979 under charter from the U. S. Congress to promote an engine for transportation that would provide an alternative to reciprocating spark-ignition (SI) engines for the U. S. automotive industry and simultaneously establish the feasibility of advanced ceramic materials for hot section components to be used in an automotive gas turbine (AGT).
