Abstract
Production of clean renewable energy capacity is increasing in demand and production. Egypt is becoming a hub for wind energy extraction worldwide with modest weather and efficient wind resources all year long.
Many researchers were carrying out research in the field of renewable energy production in the last decades since there is enormous world demand and in it. It is expected to become more common in use as installed generation capacity increases, and by year 2040 many countries should be depending on sun, air, and water exclusively, and as cost as it effective.
This thesis is concerned with the horizontal wind turbine specially to predict the lifetime of the blade due the fatigue NACA 821 wind turbine blade airfoil was used in the current analysis assuming four types of materials: aluminum, steel and two different composite materials. Finite element simulation of fatigue mechanical loading. was used the specific element analysis program ANSYS Workbench calculates the maximum value of stress and the total deformation to calculate the fatigue life of the blade according to Zafarana wind conditions. It was found that the life expectancy of the NACA 821 blade was 1011 cycles and it can undergo 107 Pa by using von Mises stresses.
