Proposal for structural testing of double root low capacity wind turbine blades based on the Iec 61400-2 Standard

In this article, the results of the numerical simulation are shown, as well as the results of the structural tests using extensometry, for a low capacity double root wind turbine blade based on the IEC 61400-2 standard. A methodology was developed to carry out the experimental plan. The results obtained by means of numerical simulation were compared with those obtained by extensometry, concluding that the blade will work safely already in operation because the values obtained from microdeformations are far from the blade failure limit
