Abstract

The wind turbine blade is a very important part of the rotor. Extraction of energy from wind depends on the design of blade. In this work a blade of length 38.95m for V821.65MW horizontal axis wind turbine (supplied by Vestas) is designed by Glauert's optimal rotor theory. A computer program is developed for getting the dimension (Twist, chord and thickness). The airfoil taken for the blade is NACA 634–221. The airfoil taken is same from root to tip. The analysis of designed blade is done in flapwise loading. The spar taken in this work is of square crosssection from root to tip of the blade. The blade and spar are of same composite material. The Finite element analysis of designed blade is done in ANSYS. This work is focused on the two segments of blade, root segment and transition segment. Result obtained from ANSYS is compared with the previously done experimental work.
