Detroit Diesel Allison (DDA), Division of General Motors Corporation, is developing the advanced technologies to make the gas turbine a viable alternative to the spark ignition and diesel engines of the future. Goals, as shown in Figure 1, have been established for fuel economy, emissions, and production cost that could allow the gas turbine to be competitive with these engines in the 1990 time frame. High-risk new technology elements are ceramic engine components and high-efficiency small airflow aerodynamic components. Current effort includes building the first AGT 100 engine, component qualification testing, and improvements to ceramic component strengths. The first engine with nine ceramic parts started shakedown testing in July. All major components and systems have passed qualification testing. Prototype silicon carbide rotors have been spin tested to 110000 rpm (127 % design speed), and new ceramic tooling is producing parts with higher strengths than those tested. Silicon nitride parts are also being developed.
