The conventional means of improving gas turbine engine performance typically involves increasing the turbine inlet temperature; however, at these higher operational temperatures the high pressure turbine blades require air-cooling to maintain durability. But air-cooling imposes design, material, and economic constraints not only on the turbine blades but also on engine performance.The use of uncooled turbine blades at increased operating temperatures can offer significantly improved performance in small gas turbine engines.A program to demonstrate uncooled MA6000 high pressure turbine blades in a GTEC TFE731 turbo-fan engine is being conducted under contract to NASA-Lewis Research Center (NAS3-20073). The project goals include demonstration of the advantages of using uncooled MA6000 turbine blades as compared with cast directionally solidified MAR-M 247 blades.
