Industry Partners: Boeing, Cessna
Objectives:
-
To develop new Hall probe technology with improved detection capability and to accelerate inspections by using multi-sensor field measurements
- To demonstrate
a linear array for wide area rapid aircraft inspection
- To demonstrate
rapid hole inspection with existing instruments but without motor driven
probes.
Approach:
- Determine optimal
material for use in Hall sensor using microelectronic fabrication facilities
at ISU
- Fabricate and test
Hall sensor to arrive at optimal design
- Build array of
Hall sensors for use in inspection around fasteners and determine sensitivity
- Complete POD study
using final probe design
- Provide comparison
to conventional probe technology and document for FAA certification
use
Advances in current sensor technologies allow for a static array to mimic the behavior of a rotating probe. Operation with existing equipment, the detection of small cracks (<40 mils) in fuselage structure could be possible.
