Industry Partners: Boeing, United Airlines, Northwest Airlines, American Airlines, Iowa Army Natl Guard, CACRC
Objectives:
-
To develop nondestructive inspection and evaluation methods that can provide quantitative information and images to aid the accept/reject decision making for repaired parts. Such techniques, with an ability to map out the morphology and mechanical condition of a repair, will provide the inspector with technical records of the repaired component while it remains inservice.
Approach:
- Survey existing repair methods and flaw types of concern. Acquire representative samples from industry partners for NDI development and destructive characterization
- Compare performance
of CATT to mechanical impedance analysis and bond testing including
use of AANC round-robin data/samples
- Develop protocol
for use of CATT including correlation between images and repair morphology
- Transition results to industry partners including on-going evaluation with Iowa Army National Guard
Development of computer aided tap test CATT and availability of ir coupled UT offers opportunites to understand the morphology and condition of a repair to establish a correlation between imaged features and the actual internal state of the repair, leading to accept/reject criteria for repaired components.
