| Résumé: | In this article, the model of a 5 kW small wind turbine blade is developed and improved.
Emphasis has been placed on improving the blade’s efficiency and aerodynamics and selecting the
most optimal material for the wind blade. The QBlade software was used to enhance the chord
and twist. Also, a new finite element model was developed using the ANSYS software to analyze
the structure and modal problems of the wind blade. The results presented the wind blade’s von
Mises stresses and deformations using three different materials (Carbon/epoxy, E-Glass/epoxy, and
braided composite). The modal analysis results presented the natural frequencies and mode shapes
for each material. It was found, based on the results, that the maximum deflections of E-glass, braided
composite and carbon fiber were 46.46 mm, 33.54 mm, and 18.29 mm, respectively |
