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.

Test Devices announces that it has increased the size of its largest spin test machine, which is now capable of testing a component up to 54 inches in diameter. This additional space will be used to not only perform simple over speed and burst tests of larger diameter rotors, but also to include instrumentation and hardware for more complex tests such as high cycle fatigue and radial growth at speed.

Test Devices announces that it has successfully demonstrated thermal mechanical fatigue capability on a jet engine component. Under a R&D project, Test Devices ran several TMF cycles on a compressor stage rotor, synching a rim to bore temperature gradient with speed. The combined temperature gradient (hot at the rim, cooler in the bore) simulated the TMF cycle the component experiences in the field. The success of this program represents a huge technological advancement in the area of component spin testing. By combining the thermal and centrifugal stresses, this test offers customers advanced component fatigue capability, providing more accurate data about component fatigue life.
