A Better Mouse Trap for Shot Peening
Improved shot peening for the CFM56-3, -5, and -7 family of jet engines by Jetair Support a Miami based MRO facility. An in-house method to automate and enhance the process maximizes quality, turnaround time and cost.
Peening a surface changes in the mechanical properties of the surface. Its main application is to avoid the spreading of micro-cracks on a surface. Such cracks do not propagate in a material that is under a compressive stress; shot peening can create such a stress in the surface. Shot peening relieves tensile stresses built up in the grinding process and replaces them with beneficial compressive stresses. Shot peening can increase fatigue life up to 1000%

Exhibiting at the MRO Americas, April 14-16 in booth #4416, Jetair will have personnel on hand to explain the new automated shot peening process.
