AGT 101 advanced gas turbine technology development program

Kreiner, D.M. / Kidwell, J.R.

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 State 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 AGT 101 powersection is a 100 hp, regenerated single-shaft gas turbine engine operating at a maximum turbine inlet temperature of 2500 F. Maximum rotor speed is 100,000 rpm. All high temperture components, including the turbine rotor, are ceramic. Development has progressed through aerothermodynamic testing of all components with compressor and turbine performance goals achieved. Some 170 hours of AGT 101 (1600 F) testing has been accumulated on three metal engines. Individual and collective ceramic component screening tests to 2100 F have been successfully accomplished. In addition, ceramic turbine rotors have been successfully cold spun to the required 115,000 rpm proof speed (15-percent overspeed) and subjected to dynamic thermal shock tests simulating engine conditions. Assembly of the first engine with ceramic. structure is underway. Engine testing of the ceramic structures and the ceramic turbine rotor is planned in the near future.
