The article reports on the use of laser shock processing of aircraft engine components. The General Electric Infrastructure-Aviation (GEA) Gen IV LSP process has presented the quality to meet the technical prospects previously set by GEA's successful Gen II process. Moreover, compressor blades of Ti6Al-4V alloy processed with GEN IV LSP showed a 2x improvement in HCF capacity with assumed foreign object damage (FOD) while still converging post-LSP distortion limits.
