Nondestructive Evaluation Technology Initiatives II. Delivery Order 0002: Whole Field Turbine Disk Inspection
Abstract
This program sought to characterize and optimize the Sonic IR inspection technique for the inspection of Air Force aircraft components through empirical methods. As part of that effort, TF33 second stage turbine blades, F100 first stage high pressure turbine disks, various compressor blades, landing gear components, and a vane ring were inspected. Elongated scallop samples and fluorescent penetrant inspection (FPI) probability of detection (PoD) samples with known flaws were also tested in an effort to understand the technique. Statistically designed studies were conducted on sets of some of these components and samples, with the analysis leading to definition of optimal operating regions for system operating parameter settings. These parameters may be used later to write test procedures for the specific components. This report covers the assembly of the Sonic IR inspection system and interface materials selection, inspection of various scrapped Air Force aircraft components, and a specimen contamination study. Also covered are the rigorous testing and analysis of the scallop samples, FPI PoD samples, F100 turbine disks, and TF33 turbine blades.
