Industry Partners: Boeing, Howmet, Northrop Grumman, Hitchcock, Pratt & Whitney
Objectives:
-
To develop optimal NDE inspections for complex aerospace castings and evaluate elements of image formation that can affect image quality, such as scattering and unsharpness effects
-
To develop probability of detection (POD) models for x-ray images and a means of determining inspection coverage for complex parts
-
To develop image processing methods to enhance detectability in the presence of diffraction mottling and for use with digital radiography detectors such that improvements are provided in the detectability over unprocessed images
Approach:
- Develop tools to ensure adequate coverage using multiple inspection orientations/zones as necessary
- Determine effects
of scattering for new real-time detectors and incorporate into modeling
tools.
- Establish the limits
of image processing tools for use in realtime inspectiion of cast components
- Develop stereography method for use in location and characterization of typical casting defects
To ensure the safe introduction of metal costings into critical aerospace components, radiograhic inspection in combination with knowledge of the effects of flow morphology/location on port lifeore often required.
Products:
- State of the art
review for FAA and industry for use in decisions regarding implementation
of new casting designs
