Introduc<on
§ Ultrasonic (UT) technology & instruments
have been used in a wide variaty of industries for NDE over the last 20 years
§ Introduction of carbon laminates composite,
in conjuction with recent low oil prices helped airline companies to save money, explaining above normal growth
OLYMPUS Scientific Solutions
Introduc<on § Consequently, aviation components manufacturers
are facing new challenges:
§ Rise in production rate § Increasingly complex geometry § Lack of skilled operators § More demanding inspection requirements
OLYMPUS Scientific Solutions
Introduc<on § Evolution of PA instruments
help address these challenges
§ Scalable PA instruments
provide the following benefits
§ Faster inspection § Improved coverage for
better repeatability § Improved radius inspection
Highpulsingfrequency
PRFUpto20kHz
Highdatatransferrate
DataThroughputUpto30MB/s
OLYMPUS Scientific Solutions
Introduc<on § Some challenges remain when full
volumetric inspection of varying geometry (varying, flatten radius, tilted parts) is required.
§ Today, these parts are either inspected manually or via complex mechanical devices that are error-prone, hard to configure, and costly
OLYMPUS Scientific Solutions
Challenges § Inspection of carbon laminate parts with the following characteristics:
§ Variable radius § Variable opening angle § Twisted
§ Inspection of non-constant (weighted) radius generated by the manufacturing process
§ Inspection of rounded flat surfaces generated by the inspection process
§ Part vs probe alignment (curved and flat arrays)
OLYMPUS Scientific Solutions
Goals
§ Improve & simplify the inspection of complex geometry components
§ Variable & weighted radius § Variable opening and twisted parts
§ Flexible solution to enable inspection from:
§ Inside & outside radius § Flat surface
§ Efficient solution
§ Inspection speed has to be similar to what is achieve today with standard phased array
§ Reliable & robust solution

Figure 2: Current implementation of Adaptive PA Figure 3: Simulation of new implementation of Adaptive PA The results and algorithm development are still preliminary but we feel we are heading in the right direction and now are looking at the feasibility of implementation of the method in the Focus PX prototype. We would like to organize a 30 min conference call with you to discuss about our progress and also discuss about the calibration of the method that will be the next point we will address. We are open next week from Tuesday to Friday, let us know what would work best for you.
