16 B-scan versus C-scan Defect

17 Impact Damage in Composite Structure
One inch Leading Edge Inspection

18 Pulse Echo of Honeycomb Composite
One inch

19 Range Gating Gate 1 Gate 2 Gate 3

20 Range Gating for Depth: Pick the C-scan plane of interest

21 Integrated A-scan for Flaw Detector Functionality
“Transparent” A-scan Sensor

22 Presentation of Imagery and A-scan/ Match Gates
Set A-scan gates, automatically changes C-scan gates

23 Production Scanning Results: ATK Thiokol
Hex nut and paper clip placed on surface Graphite/epoxy laminate defect standard with embedded Teflon wafers

24 UT camera scan with stitching algorithm applied
- 0.3” scan increment Conventional immersion scan MHz, 0.25” diameter transducer scan increment

25 Gridlines/Sizing

26 Future Developments: Pulse Echo
Handheld portion goes from 4 lbs. to 2 lbs.

27 Current Development: ‘Camcorder’ Handheld
Focus with finger Strap Grip Handheld portion goes from 4 lbs. to under 2 lbs.

28 New Control Unit

29 Current Development: ‘Camcorder’ Handheld

30 Time of flight: color code different depths
Blue: Level 1 Red: Level 2 Yellow: Level 3 2 3 3 1 2 Increments to be selected by user (e.g. 1 mm)

31 Future Developments: Through Transmission

32 Boeing Remote NDI Program
Lack of trained NDI personnel Use by non-certified personnel SIMPLE, SIMPLE, SIMPLE Remotely monitored in real time Wireless Program began in early 2007

33 Remote Wireless NDI Program
C-scan, A-scan, Audio, Video of inspection Audio, Control of camera

34 Boeing Remote NDI Program
Successful demonstration Fall 2008 Equipment at Boeing’s Everett, WA production facility Remotely monitored at Boeing’ GoldCare center in Seattle, WA Pilot program with airlines during 2009
