ARMY-NASA Partnership at
Lewis Research Center
Turbines
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.
