Blades and Damper Testing
Dynamic Spin Testing
Test Devices' Dynamic Spin Testing provides the ability to excite airfoil vibratory modes of fully bladed engine rotor stages. This dynamic testing method enables characterization of the vibratory performance of blade designs to evaluate the effectiveness of damper designs and to assess the high cycle fatigue life of blade and damper systems. Tests can be conducted at ambient temperature or elevated temperatures exceeding 1000°F.

Rotor Testing Services
Balance Services
Test Devices offers balancing services both in support of its spin testing services and for production applications not requiring spin testing. At-speed balancing is also offered in a vertical spin chamber when customer requirement calls for high speed balancing.
Low Cycle Fatigue Testing
Establishing the fatigue life of a rotating component is critical to establish safe working life criteria. Test Devices offers LCF spin testing services with rapid cycling capability that accelerates fatigue testing programs, providing customers with life assessment data earlier. Optional crack detection can monitor component integrity in real time, enabling a test to be stopped prior to rotor failure.
Growth Measurement at Speed
Test Devices can measure elastic and plastic radial growth of components in real time at speed. This technique can verify stress and growth models and determine precise gaps between rotating and stationary components in turbomachinery.
Burst Testing
Spin burst testing provides customers with an efficient method to validate rotor designs and establish component safety margins. All tests are performed under the safest conditions, in a robust spin chamber installed in a test cell with double-reinforced concrete walls and ceiling. Optional high speed video recording of the burst event can provide invaluable information about the rotor failure mechanism
Proof Testing
Test Devices offers spin proof testing services for proof of design (R&D), overspeed and pre-spin testing of rotor forgings. Several optional services can be added to any proof test to provide customers with important information about the component under test.
Strain Survey
Test Devices offers comprehensive strain surveys of complex rotating parts. Strain surveys enable customers to understand assembly stresses and determine the properties of materials (including composites) when exposed to operational strain under realistic conditions.
Tooling & Arbors
Precision design, analysis and manufacture of spin tooling (fixturing) are critical to effectively spin test complex, highly stressed, rotating components. Test Devices' engineers utilize extensive experience and three dimensional modeling and analysis software to ensure spin tooling meets customer requirements.

One Stop Spin Testing
Test Devices has developed a group of strategic partners – expert and dependable vendors who provide adjunct services to spin testing. This allows customers to produce a single purchase order to Test Devices and benefit from seamless project management, start to finish.
Data Acquisition & Reporting
All data (including speed, vibration, temperature, and strain) is recorded on digital data acquisition systems. Customers can be provided with color printouts of the data and electronic copies of the raw data when necessary. Test Devices archives the digital data indefinitely for future customer reference.
Thermal Gradient
During operation, rotating components are exposed to stresses due to thermal gradients that can exceed the centrifugal stresses. Test Devices can provide customers with more relevant test data by performing spin tests with thermal gradients that more closely simulate the complete stress state experienced by components in operation.
