Evaluation of OBR for strain measurements in blade
testing.
Overview
DIAPOSITIVA 1
• Duration: 2008-2009.
• Project: Private research contract.
• Partners: Gamesa Innovation & Technologies
• UPM responsibilities: The main aim of the project was to validate the
OBR technology for strain measurement, comparing blade strains
obtained during a static test with this technique to those recorded with
Strain Gauges, as well as developing simple retrofit methods for fibre
installation.
