Abstract
An apparatus and method for testing vibration in a bladed disk includes a motor-driven rotor upon which the bladed disk can be attached. At least one nozzle coupled with a liquid source is positioned to direct liquid from the liquid source to a position where it would impact at least one blade of the rotating bladed disk. The stress state and/or position of a rotating blade, so impacted, can be monitored to test its vibration characteristics.
