This work presents shape optimization of S809 airfoil under compressible flow using CFD simulationsoftware. The FLUENT software is used for calculation of the flow field. Optimal S809 airfoil shape is obtained whichincreases both ????L and ????L/????D for a given, rotational speed and wind speed. The results showed that aerodynamicscharacteristics of optimized S809 are improved significantly.In this work compressible flow condition has considered. Day by day development of WT blade airfoil is going on andhas got many modifications to improve the performance for wind conditions and special application. To get higherefficiency the blade should have correct aerodynamic shape. This aerodynamic characteristic should be to give the bestpossible energy capture for the site conditions and rotor speed. Length of the blade of a WT is increasing day by day. Fora 100mblade rotating at 25 rpm the tip speed of WT will approximately reach a Mach no. of 0.78. Therefore an analysisand optimisation under compressible flow might be helpful for the designer to avoid unexpected incidents.
