    • A nozzle assembly (10) for a turbine engine includes an inner band (16) and an outer band (14) spaced apart from each other. An airfoil (12) installed between the bands has a leading edge (18) and a trailing edge (20). The airfoil has cavities formed in it for fluid flow through the nozzle assembly. A plurality of film cooling holes (1A–6H) are formed in a sidewall of the airfoil on a concave side of the assembly, and a plurality of film cooling holes (1J–1R) are formed in a sidewall of the nozzle on a convex side thereof. The holes are formed on each side of the airfoil, adjacent the trailing edge of the nozzle, in a plurality of rows of holes including at least a forward row (C, J), an aft row (A, L), and an intermediate row (B, K). The spacing between the intermediate row and aft row is substantially closer than the spacing between the forward row and the intermediate row.
    • 用于涡轮发动机的喷嘴组件(10)包括彼此间隔开的内带(16)和外带(14)。 安装在带之间的翼型件(12)具有前缘(18)和后缘(20)。 机翼具有形成在其中的空腔,用于流过喷嘴组件的流体。 在组件的凹面上的翼型件的侧壁上形成有多个薄膜冷却孔(1A-6H),并且在该侧壁中形成多个薄膜冷却孔(1J-1R) 喷嘴在其凸面上。 所述孔形成在所述翼型件的与所述喷嘴的后缘相邻的每一侧上,所述多排排孔至少包括前排(C,J),后排(A,L)和中间体 行(B,K)。 中间行和后排之间的间隔基本上比前排和中间行之间的间距更近。
