- Developed method for detecting and characterizing marcels (fiber waves) in solid laminate composites using surface waves, with the method being further tested in a manufacturing and remote field environments.
- Developed and tested a manual generic scanner for application of imaging methods to commercial hand held nondestructive evaluation instruments. Beta-tested the technology with airlines, aircraft OEMs, US Air Force and US Navair.
- Developed, field tested and commercialized Computer Aided Tap Tester (CATT) for nondestructive evaluation of composite and honeycomb structures on aircraft. Transferred this technology to airlines, aircraft OEMs and other NDE research organizations. Assisted NTSB in the AA587 Airbus accident investigation in 2001 and 2002 with the CATT instrument.
- Field tested and commercialized Dripless Bubbler ultrasonic scanner for detecting and imaging corrosion on aluminum aircraft fuselage and wing structures. The technology received an R&D100 Award for 1996 and was transferred to an Air Force ALC.
- Developed air-coupled ultrasonic scan methods for inspecting composites and their repairs. Transferred technology to NASA for fabricators NDE of Hubble space telescope carrier.
