As part of the Department of Energy activities to reduce turbine engine fuel consumption. Detroit Diesel Allison has been actively involved in a program to apply ceramic components and demonstrate improved cycle efficiency in the existing 404/505 vehicular gas turbine engine. Ceramic components will permit increased gas turbine operating temperatures and improve cycle efficiency. Initial ceramic components that have been engine tested and evaluated at an engine operating temperature of 1038 degree C (1900 degree F) include regenerators, vanes, and turbine tip shrouds. Engine test experience totals over 4000 hr on aluminum silicate regenerators, 1400 hr on silicon carbide nozzle vanes and 500 hr on silicon carbide turbine tip shrouds.
