Effect of Shot Peening on Lo Disc of a Typical

This investigation deals with the study of a compre having a TBO (Time Between Overhaul) of 550 hour most of compressor discs is attributed to low cycle dovetail slots. In the present study, shot peening wa slots in order to enhance fatigue life of the disc. The l increases upto 450 MPa and 230 MPa, respectiv compressive stresses measured by XRD technique o MPa & 770 MPa, respectively. Stress controlled LC 0.33 Hz) have been conducted at room temperature. T as compared to that of unpeened disc. Following this hours, thereby eliminating the need of disc repla serviceability of the fleet.
