Acoustic Emission Defect Detection in Wind Turbine Blade.
The Experiment helps the students to understand the acoustic emission condition monitoring technique for detecting the defect in wind turbine blades. Learning the different acoustic properties of materials is an essential part of the course and is currently addressed during lectures and tutorials. However, many students still have a lot of confusion in using this technique. In the Acoustic emission experiment, we try to clarify the AE concepts and how it can be used for damage detection.

Damage Location in Wind Turbine Blade.
The Experiment helps the students to understand how to locate the defect in wind turbine blade in one dimension or in other word axially. This defect can be a delamination in the layers, cracks, fibre breakage, fibre pull-out. The acoustic emission technique is famous for its ability to locate the damage in the structure by knowing the time of arrival of the signals and simple equations to describe the position. In this experiment, the linear location technique with knowing the time of arrive will be considered. We try to clarify the acoustic emission linear location method and how it can be used for damage locating on wind turbine blade. However, it must be noted that this experiment is for demonstrating the linear location concept.

The Experiment shows how to locate the defect in solar panel in two dimensions or in other word planar location. This defect can be a microcrack in the cell laminates, cracks, cell breakage, hot spot, delamination and corrosion. The acoustic emission technique is famous for its ability to locate the damage in the structure by knowing the time of arrival of the signals and simple triangulation equations to describe the position. In this experiment, the 2D location technique with knowing the time of arrival of the waves will be considered.

Carbon Footprint in Renewable Energy Manufacturing and Installation.
This tutorial presents three wind turbine blade manufacturing techniques and the corresponding transportation and demonstrates the carbon footprint emission for each transportation case. The first technique is the conventional wind turbine blade manufacturing, the second one is the segmentation concept for the wind turbine blades, and the third one is the innovative inflatable wind turbine blade. The major source of carbon emissions is the transportation means.
