Example Embodiment

[0023] Refer to the following Figure 1 to Figure 6 , And further describe the preferred embodiments of the present invention in detail. The multiple embodiments of the present invention can have multiple variations, and the scope of the present invention is not limited by the multiple embodiments described below, and is only used to provide those of ordinary skill in the art to which the multiple embodiments of the present invention belong. More detailed description. Therefore, in order to more clearly emphasize and explain the problem, the shapes of the various components shown in the drawings may be exaggerated.

[0024] figure 1 Shown is a situation where the propeller is set in a wind tunnel. The wind tunnel 10 is arranged horizontally, a fan is arranged at the right end of the wind tunnel, and an exhaust port is formed at the left end of the wind tunnel. The fluid flow (V1) provided by the fan passes through the (V) propeller 20 and then faces the (V2) exhaust port.

Abstract

According to one embodiment of the present invention, a rotating blade, having a collision face that collides with fluid and is rotated by the flow of said fluid, has at least one flow path that has been caved in from said colliding face; said flow path is located forward with respect to said rotation direction so that it is located in the rear with respect to the inlet whereinto said flow is introduced and said rotation direction, and it has an outlet from which said fluid exits. Here, the cross-sectional area of said inlet may be greater than the cross-sectional area of said outlet. In addition, the cross-sectional area of said inlet may gradually decrease toward said outlet.

Description

technical field [0001] The present invention relates to a rotary blade and an airfoil, and more particularly, to a rotary blade and an airfoil that rotate or lift with the flow of fluid. Background technique [0002] Wind energy has long been used as a source of mechanical power. The wind force generated by the air flow is transmitted to the blade as the wind hits the impact surface of the blade. When the blade rotates with the wind force, the wind energy is converted into mechanical energy. The above-mentioned mechanical energy can be converted into electrical energy through the turbine, and at this time, along with the energy conversion, the problem of conversion efficiency arises. [0003] In order to obtain a large amount of electrical energy from the same mechanical energy, it is advisable to make the blades have high energy conversion efficiency. That is, when wind energy is initially converted into mechanical energy by blades, the amount of mechanical energy that ca...
