NUMERICAL ANALYSIS OF WIND TURBINE BLADES MANUFACTURED FROM COMPOSITE MATERIALS AT DIFFERENT VELOCITIES AND ARRANGEMENTS

Since wind turbines are found all over the world, technology for acquiring

renewable energies must be developed. The work of wind turbines depends mainly

on generating wind energy and converting it into electrical energy. And the

materials manufactured for wind turbines can withstand the pressures and forces

coming from the wind. The problem lies in resolving the fatigue phenomenon in

wind turbines because of changes in air pressure. To solve this problem, it is

necessary to use composite materials, which have become a major part of industrial

applications due to their ability to withstand various mechanical conditions. An air

turbine was designed and simulated the amount of pressure generated from the air.

Thus, the best arrangement of composite materials was made to obtain the strongest

bearing capacity for the turbine. The model was designed based on the main

dimensions of the FFA-W3, NACA-63-xxx, MIX turbine. The result shows the

ideal situation is achieved by arranging the angles, which is the stress value of a

turbine blade when it moves at a speed of 15 m/s and possesses 358650 Pa. The

fundamental working mechanism of composite materials is the strategy of

arranging composite materials with the necessary angles to achieve the best

configuration that can withstand large loads and not fail under them. Compared to

other examples, the arrangement of the angles (0,0,0) prefers bearing deformations

and stresses, and it can withstand the phenomenon of fatigue
