The Army Vehicle Technology Center and NASA Lewis have jointly conducted both experimental and analytical investigations over a broad range of turbine technologies. These have included aerodynamics, heat transfer, turbine cooling and life prediction. Typical are the detailed flow visualization and heat transfer experiments conducted on a configuration representative of internal turbine cooling passages. Results have proved invaluable in guiding the development of advanced turbine cooling codes. These efforts have been conducted in-house, as well as under contracts with industry and grants with academia. Emphasis in the turbine arena has shifted somewhat from fundamental aerodynamic and heat transfer investigations to include the application of emerging materials technology (specifically Ceramic Matrix Composites - CMC's) into turbine hardware. In a cooperative effort between the Army, NASA, and Allied Signal Engines, a CMC turbine transition duct is being developed for an advanced engine application. The use of CMC's instead of traditional metal construction is expected to result in a lighter component, as well as a one percent reduction in required cooling air flow. A CMC turbine nozzle is also being investigated for the same engine application.
