There are two types of vertical axis wind turbine, drag-type and lift-type. The drag-type has a small starting torque, but its peripheral velocity does not exceed the wind velocity. As for the lift-type, its peripheral velocity exceeds the wind velocity, but starting torque is large. A hybrid vertical axis wind turbine that has both these advantages was examined in this study. The blade cross-section that has been specially designed for the hybrid vertical axis wind turbine was proposed. Aerodynamic force generated by this blade was evaluated by wind tunnel experiments and numerical simulation in range of 9000<Re<120000. Results obtained this examination shows suppress of separation and generation of lift force in adverse wind condition, which results in improvement of blade performance.
