Statistical Analysis of 59 Inspected SSME (Space Shuttle Main Engine) HPFTP (High Pressure Fuel Turbopump) Turbine Blades (Uncracked and Cracked)

摘要

The numerical results of statistical analysis of the test data of Space Shuttle Main Engine high pressure fuel turbopump second-stage turbine blades, including some with cracks are presented. Several statistical methods use the test data to determine the application of differences in frequency variations between the uncracked and cracked blades.
