A New Spin On Turbine Blade Testing
Hudson, MA
There are two types of stress happening to a turbine blade; an alternating or vibration stress and centrifugal static stress. As blades rotate, they experience natural resonant frequencies at different rpms . While vibrating, the blade is also under a centrifugal load as if it is being pulled from root to tip while vibrating. For a complete stress test, all stresses should be tested for both simultaneously.
