10” diameter phased array,(go/no go decision
at 30 months)
(Critical review with FAA, seek program redirection
to develop phased arrays) (All)
Complete preliminary phased array surveys. (PW)
Evaluate up to three candidate phased array
systems.
Identify preferred configuration for factory
evaluation system.
Design and build improved phased array
transducer assembly.
Factory Evaluation / Demonstration
36 months* 44 months Complete factory test of five heats. Conduct
industry demonstration of #1FBH capability in 10”
diameter. (GE, PW)
38 months* 46 months Evaluate indication finds from factory test,
document results. (GE, PW, ISU).
40 months 48 months Report of laboratory and factory evaluations
including sensitivity data for use by the Inspection
Systems Capability Working Group and cost
comparisons for the different inspection
approaches. (All)
Large diameter billet
12 months Build chord calibration standard for 14” diameter,
near-center region. (PW)
18 months 20 months Evaluate capability on 13” and 14” diameter using
conventional and zoned fixed focus, determine
improvement over conventional. Provide data to
3.1.1 for model validation and POD estimation for
large diameter billet. (GE, PW, ISU)
20 months 24 months Laboratory assessment of sensitivity at diameters
greater than 10" diameter using fixed focus
transducers. (All)
General issues
28 months Complete attenuation compensation procedure in
cooperation with 3.1.1. (ISU with support from PW
and GE)
30 months Procedures to account for attenuation effects that
occur in titanium billet and thus improve the POD of
billet inspection. (All)
