Abstract
A wind control blade () of a wind guide () of the present invention forms a 20° wind control blade lateral curved surface gradient angle (), a 30° wind control blade longitudinal spiral twist angle (), a 180° wing control blade alignment angle (), and a 15° wind control blade rear gradient angle (). In addition, a turbine blade () forms a 30° turbine blade lateral curved surface gradient angle (), a 40° turbine blade longitudinal spiral twist angle (), and a 120° turbine blade alignment angle (). The 20° wind control blade lateral curved surface gradient angle () and the 30° wind control blade longitudinal spiral twist angle () of the wind control blade () have more gradual and wider incidence angles than the 30° turbine blade lateral curved surface gradient angle () and the 40° turbine blade longitudinal spiral twist angle () of the turbine blade (). Accordingly, since more wind enters into the central direction of the inner side of the turbine blade () and a primary whirlwind is generated, much higher acceleration can be obtained.
