methodology
12 months TBD Report results from applying RDB and CBS data to
validate the ISU models developed in Phase I.
(ISU, with support from AE, GE, PW)
12 months TBD A report assessing success of the Phase I
development of a new POD methodology.
Ongoing
Modify the modeling software if and when
necessitated by experimental data. (ISU)
30 months Review and report on effects on POD of calibration
response variability, and uncertainty in determining
flaw size, conducted on Nickel only. (GE, with
support from ISU) Provide OEMs with integrated
software containing flaw response and noise
models. (ISU)
30 months Report documenting the software and material
characterization procedures with which the OEMs
can implement the new methodology.
48 months Complete development and validation of models for
the effects of microstructure on beam profiles and
apparent attenuation. (ISU, PW with support from
GE, AE)
60 months
TBD
Provide OEMs with final software and procedure
packages. (ISU)

POD for titanium billet – existent/new data analysis,
and use of the CBS
12 months TBD Complete report of analysis of CBS data. (ISU,
with support from AE, GE, PW)
Ongoing
Updated POD estimates for naturally occurring
flaws in titanium alloys as new field-find data
become available. (GE, ISU, with support from AE,
ISU)
42 months
Initiate POD assessment of revised inspection
approaches for large diameter billet (10″ to 14″).
(PW with support from ISU, GE) Characterize
transducers to be used in inspection of large
diameter billets. (Utilize results from 1.2.1)
42 months Report documenting the revised estimates of POD
for larger diameter titanium billet
51 months Predict response for large diameter billets. Use
calibration standards, RDB, and chord blocks for
validation as appropriate. (ISU with support from
PW, GE)
Provide POD estimate for larger diameter billet.
(ISU, with support from AE, GE, PW) Compare
results with those from alternative POD
methodologies. (GE, with support from ISU)
51 months Report documenting the estimates of POD and
PFA for titanium billet based on use of the random
defect block, CBS data, and data reported to
JETQC, including comparison with POD results
from existent methodologies.
Completion of full report delayed by
redirection of work.
