Title:
WING AND MACHINE HAVING THE SAME
Document Type and Number:
Japanese Patent JP2020132113
Kind Code:
A
Abstract:
To provide a wing capable of suppressing separation that may occur on a wing surface, and to provide a machine having the same.SOLUTION: A wing comprises one communication hole 70 having a first opening end 72 that passes through the inside of an airfoil section and opens to a first wing surface 65 and a second opening end 74 that opens to a second wing surface 66. The first opening end is positioned on a first cross section orthogonal to a wind width direction, and the second opening end is positioned on a second cross section orthogonal to the wind width direction. On the first cross section or the second cross section, there exists an angle A1 that meets a condition (a) within an angle range from -10 to +10 degrees around a front edge 61 on the basis of the straight line parallel with an inflow direction of fluid to the airfoil section 60. The condition (a) is a condition in which when the airfoil section receives the flow of fluid in a direction to the front edge from a direction of the angle A1, the static pressure at the position of the first opening end on the first surface is equal to the static pressure at the second opening end on the second wing surface.SELECTED DRAWING: Figure 2
