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.
