Abstract:  
The Customer's Problem A manufacturer of aircraft propellers was shot peening the shank, the portion of a propeller blade that mounts to the hub. The hub is the center section of the propeller, which carries the blades and is attached to the engine shaft. They shot peen the shank to maximize its fatigue life. It goes without saying that the propellers perform a function critical to the operation of the aircraft. Therefore, shot peening specifications must be followed precisely.
