Objectives:

• Support the application and transfer of dual probe UT techniques for the detection, characterization and sizing of defects in multilayered structures
  

• Provide method for the systematic selection of UT wave modes and transducer configurations based on spatial orientation of layers, fasteners and flaws
  
  
• Develop modular inspection system for UT
  
  
• Integrate commercial scanning system with data acquisition modules and portable flaw detectors
  
  

Approach:

• Define inspection requirements/geometries
  
  
• Design prototype scanning units which do not require direct placement of the scanner on the component using interchangeable mounting plates and commercial transducers
  
  
• Develop appropriate data acquisition and data display (imaging) schemes
  
  
• Transition capability through field demo and validation activities in cooperation with AANC and industry
  
  

Products:

• Inspection techniques for application to Boeing, Cessna, and Fairchild planes
