Tip loss corrections are a critical factor in blade element
momentum theory when determining optimum blade shape
for maximum power production. Using numerical and
analytical optima, this paper compares the optimal tip shape
using the classical tip loss correction of Glauert. A semianalytical solution was proposed to find the optimum rotor
considering Shen's new tip loss model. The optimal blade
geometry is obtained for which the maximum power
coefficient is calculated at different design tip speed and
glide ratio. Our simulation is conducted four S809 rotor
wind turbine blade type, produced by National Renewable
Energy Laboratory (NREL).
