Abstract

Content: Turbine blade fatigue failures began to occur on the Garrett Air Turbine Starter, Model ATS200-58, in commercial airline service. A comprehensive program including metallurgical analysis, finite-element analysis, and strain gage testing of instrumented turbine wheels resulted in large quantities of data on blade vibratory strain. The results of testing various configurations, including the addition of damping and the use of different numbers of stator vanes, are presented.
