Nondestructive Evaluation (NDE) Technology Initiatives Program (NTIP) Delivery Order 0029: Advanced Thermosonic Methods (SONIC IR)
Abstract
The overall objective of this program was to demonstrate that the Sonic Infrared (IR) inspection technique can be used reliably to detect a fatigue crack located at the anti-rotation feature on the F100 first stage turbine disk. As the physics of the mechanical energy to thermal energy conversion for this technique is not well understood at this time, an empirical approach was used to develop the system parameters that will enable a reproducible inspection technique to be developed. This Delivery Order covered a literature and subject matter expert search, development of a Design of Experiments (DoE) test plan, production of a test fixture, and preliminary interface and fixturing materials testing. Fixturing and coupling were identified as key parameters for reliability. Testing was continued on a follow-on program.
