    • An airfoil (200; 360; 700) is disclosed comprising a distal edge (224; 324), a proximal edge (222; 326), a pressure side surface (238) extending between the distal edge (224; 324) and the proximal edge (222; 326) and between a leading edge (236; 736) and a trailing edge (242; 742), the leading edge (236; 736) forward of the trailing edge (242; 742), wherein a first cooling hole (216; 316) and a second cooling hole (218; 318) are disposed in the pressure side surface (238), wherein the first cooling hole (216; 316) is oriented at a first angle (θ) relative to the distal edge (224; 324) and the second cooling hole (218; 318) is oriented at a second angle (φ) relative to the proximal edge (222; 326), wherein the first angle (θ) and the second angle (φ) have bilateral symmetry about a plane (230; 330), wherein the plane (230; 330) is located at a point at least one of more than or less than the midpoint between the distal edge (224; 324) and proximal edge (222; 326).
    • 公开了一种翼型件(200; 360; 700),其包括远侧边缘(224; 324),近侧边缘(222; 326),在所述远端边缘(224; 324)和所述近端 边缘(222; 326)并且在前缘(236; 736)和后缘(242; 742)之间,前缘(236; 736)在后缘(242; 742)的前方,其中第一冷却孔 (216; 316)和第二冷却孔(218; 318)设置在压力侧表面(238)中,其中第一冷却孔(216; 316)相对于远端边缘 (224; 324)和第二冷却孔(218; 318)相对于近侧边缘(222; 326)以第二角度(Æ)定向,其中第一角度(¸)和第二角度(Æ)具有 关于平面(230; 330)的双边对称性,其中所述平面(230; 330)位于远端边缘(224; 324)和近侧边缘(222; 324)之间的中点之中至少之一处的点处; 326)。
