Abstract
Testing method for determining the distribution of a physical property along a wind turbine blade comprising the following steps: a) installing inside the blade a first optical fiber cable () along the leading and trailing edges and a second and third centered optical fiber cables () at both sides of the blade (), leaving in them a free end; b) applying one load to the blade () in a test bench () placed at the blade factory; c) obtaining the strain distribution produced by said load along the blade () using a suitable external equipment connected to said free end for measuring the strain using Rayleigh scattered light; d) determining the distribution of said physical property from said strain distribution; e) comparing the distribution of said physical property with its design distribution. The invention also comprises a method of installation of said cables.
