Introduction
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 $$$
explaining above normal growth
OLYMPUS Scientific Solutions
Introduction
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
Introduction
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
High pulsing frequency
PRF Up to 20 kHz
High data transfer rate
Data Throughput Up to 30 MB/s
OLYMPUS Scientific Solutions
Introduction
Some challenges remain when full
volumetric inspection of varing
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 laminates parts with the following characteristics :
Variable radius
Variable opening angle
Inspection of non-constant (weighted) radius generated by the
manufacturing process
Inspection of rounded flat surfaces generated by the manufacturing
process
Part vs probe alignment (curved and flat arrays)
Variable Radius Variable Opening
Weighted
OLYMPUS Scientific Solutions
Goals
Improve & simplify the inspection of complex geometry components
Variable & weighted radius
Variable opening and twisted parts
Flexible solution to allow inspection from :
Inside & outside radius
Flat surface
Performant solution
Inspection speed has to be similar to what is achieve today with standard phased array
Reliable & robust solution
Outside Inside

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.
