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, the analysis is done on a blade of length 38.95m which is designed for V82-1.65MW horizontal axis wind turbine (supplied by Vestas). The airfoil taken for the blade is NACA 634–221 which is same from root to tip. The analysis of designed blade is done in flap-wise loading. Two shapes of the spar are considered in this work one of them is of square shape and the other one is combination of square and cross shape. The blade and spar are of the 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.
