Disclosed in the present invention is a wind turbine having a structure comprising an influx hole for flowing in wind on one side of blades, while accommodating wind inside the blades. At the same time, the air flowed in through a flow passage can be discharged to the opposite direction of the progressing direction of the blades, by an additionally prepared air efflux hole. The size of the cross section of the efflux hole is relatively smaller than the influx hole, thus making air be discharged at high velocity to accelerate the rotation velocity of the blades. |
