RISFatigue Crack Growth Behavior Evaluation of Grainex Mar-M 247 for NASA’s High Temperature High Speed Turbine Seal Test Rig
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fatigue crack growth behavior of Grainex Mar-M 247 is evaluated for NASA’s turbine seal test facility. The facility is used to test air-to-air seals primarily for use in advanced jet ...
Strain-Life Assessment of Grainex Mar-M 247 for NASA’s Turbine Seal Test Facility
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: NASA’s turbine seal facility tests air-to-air seals for advanced jet engines. High temperature, speed, and pressure combinations limit test disk life, due to crack initiation in the Grainex Mar-M ...
