Keywords: spin rig, blade, damper, vibrostress, high cycle fatigue

It is shown that Dynamic Spin Rigs can be effectively used for optimization of structural damping of blade vibrations, for high cycle fatigue testing of rotating blades and for validation of Goodman Diagrams. Specific features of Dynamic Spin Rigs are discussed. Some test results are presented.
