Abstract

Proposed is an airfoil (2000_1, 2000_2, 2000_3, 2000_4) including a suction surface (2400), a pressure surface (2300), a leading edge (2100), a trailing edge (2200), and a through hole (2500, 2500_2, 2500_3, 2500_4). The suction surface (2400) protrudes with an outward convex curved surface. The pressure surface (2300) is formed on a surface opposite to the suction surface and has a curved surface recessed concavely. The leading edge (2100) is arranged at an upper stream of an air flow and formed where front ends of the pressure surface (2300) and the suction surface (2400) are joined. The trailing edge (2200) is arranged at a lower stream of the air flow and formed where rear ends of the pressure surface (2300) and the suction (2400) surface are joined. The through hole (2500, 2500_2, 2500_3, 2500_4) is formed through the airfoil (2000_1, 2000_2, 2000_3, 2000_4) in a direction from the pressure surface (2300) to the suction surface (2400).
