abstract

The Garrett/Ford Advanced Gas Turbine (AGT) Technology Project, authorized under NASA Contract DEN3-167, is sponsored by and is part of the United States Department of Energy Gas Turbine Highway Vehicle System Program. Program effort is oriented at providing the United States automotive industry the high risk long-range technology necessary to produce gas turbine powertrains for automobiles that will have reduced fuel consumption and reduced environmental impact. The AGT101 power section is a 74.6 kW (100 hp), regenerated single-shaft gas turbine engine operating at a maximum turbine inlet temperature of 1371°C (2500°F). Maximum rotor speed is 10,472 rad/sec (100,000 rpm). All high temperature components, including the turbine rotor, are ceramic. Development has progressed through aerothermodynamic testing of all components with compressor and turbine performance goals achieved. Some 200 hours of AGT101 testing has been accumulated at a nominal 871°C (1600°F) on three metal engines. Individual and collective ceramic component screening tests have been successfully accomplished at temperatures up to 1149°C (2100°F). Ceramic turbine rotors have been successfully cold spun to the required proof speed of 12,043 rad/sec (115,000 rpm), a 15-percent overspeed, and subjected to dynamic thermal shock tests simulating engine conditions. Engine testing of the ceramic structures and of the ceramic turbine rotor is planned in the near future.
