2. Description of the Related Art As shown in FIG. 10, a conventional wind turbine for power generation has a plurality of wind turbine blades 1, a nacelle 2 in which a generator and the like are housed, and a standing wind turbine on the ground to support the nacelle 2. Tower 3
And is provided. FIG. 11 is an explanatory view schematically showing the force that the wind turbine blade receives from the airflow. In FIG. 11, reference numeral 6 indicates a virtual straight line connecting the blade leading edge 4 and the blade trailing edge 5. Is called chord. Reference numeral 7 indicates a chord 6
And an airflow direction, and this angle is called an angle of attack. The airflow flows from the upstream side of the blade front wing 4 to the downstream side of the blade trailing edge 5, and the passage of the airflow generates a pressure distribution on the blade surface and a frictional force between the airflow and the blade surface. As a sum of these forces, the wing receives a lift 8 acting in a direction perpendicular to the airflow and a drag 9 acting in the direction of the airflow. In general, the windmill blades can extract the wind energy more effectively as the wing rotation force as the lift is larger and the drag is smaller.
The amount of power generation also increases.

By the way, since the windmill is installed outdoors, bird feces and insects flying on the wind collide with the windmill blades during long-time use, and the vicinity of the leading edge becomes dirty. Since dirt on the leading edge impairs the smoothness of the blade surface, the flow near the blade surface on the downstream side is more likely to be changed from a laminar flow state with small turbulence to a turbulent state with strong turbulence.

FIG. 12 shows a representative example of the relationship between the drag received by the airfoil from the airflow and the angle of attack. In FIG. 12, the dashed line shows the case where the blade leading edge is smooth and the blade surface flow is laminar, and the solid line shows the case where the blade leading edge is provided with roughness and the blade surface flow transitions to turbulent flow. In each case, the airflow velocity is constant.

As shown in FIG. 12, when the wing surface flow transitions to a turbulent state due to the roughness provided near the leading edge of the wing, the friction between the air flow and the wing surface increases, and the drag received by the wing from the air flow hardly increases. At the angle of attack. As described above, in the conventional wind turbine blade, there is a problem that the drag received by the wind turbine blade from the airflow increases due to the contamination of the leading edge due to long-time use, and the performance is deteriorated.
