Case History---Peer-Reviewed


Gas turbine axial compressor blades are designed to withstand cyclic stress loading resulting of modal vibrations. However, when surface suffers from foreign object damage, a fatigue crack is likely to initiate. In this paper two failure case-studies of titanium alloy used for aeroderivative gas turbine compressor blades are presented. Both are related to a failure of first stage compressor blades coming from different turbine power ranges. Observed cracks were found at blade spans corresponding to modal vibrations.
