blades and a composite prototype of a wind generator with helical blades. Numerical structural analyses
are performed by means of FEM models by using ANSYS MechanicalTM software package. Furthermore,
laboratory dynamic experimental tests are carried out on real scale specimens of the two wind generator
configurations in order to find their modal properties in terms of natural frequencies and modal shapes.
The results of the experimental campaign are then used to update the numerical models by minimizing
an objective function. Total stresses and deformations of the two wind generator configurations, coming
from the updated numerical models, are evaluated and compared to quantitatively point out the
improvement of the structural behaviour obtained by the use of composite materials.
