Acoustic emission (AE) non-destructive
testing techniques are being developed during a series of static and
fatigue tests on small and commercial scale blades and demonstrated
on an in-service turbine. Real-time monitoring of these tests will
contribute further to the understanding of failure processes in the
blades and form the basis for feeding back information to designers
for optimisation of the design and manufacturing processes. The data
are being analysed using pattern recognition software in order to
develop quantifiable evaluation criteria (acceptance / rejection)
for application during static and fatigue testing of wind turbine
blades.
