    • An airfoil includes an airfoil section having an external wall and an internal wall (184). The internal wall (184) defines a reference plane (185) extending in a spanwise direction along a surface of the internal wall, a first cavity (179) and a second cavity (180) separated by the internal wall (184), and a plurality of crossover passages (183) within the internal wall (184) and connecting the first cavity (179) to the second cavity (180). Each of the plurality of crossover passages (183) defines a passage axis (187). The passage axis (187) of each of the plurality of crossover passages (183) is arranged at a radial angle relative to a localized region of the reference plane (185) such that the radial angle of at least some of the plurality of crossover passages (183) differs in the spanwise direction.
    • 翼型件包括具有外壁和内壁(184)的翼型部分。 内壁(184)限定沿着内壁的表面沿翼展方向延伸的参考平面(185),由内壁(184)分开的第一空腔(179)和第二空腔(180),以及 在内壁(184)内的多个交叉通道(183)并将第一空腔(179)连接到第二空腔(180)。 多个交叉通道(183)中的每一个限定通道轴线(187)。 多个交叉通道(183)中的每一个的通道轴线(187)相对于参考平面(185)的局部区域以径向角度布置,使得多个交叉通道中的至少一些交叉通道 (183)在翼展方向上不同。

    • Core assemblies and methods for manufacturing components of gas turbine engines (20) include a first core body (1070a) having a first trunk (1072a) configured to attach to a first location of a cavity core structure, a first branch (1074a) extending from the first trunk and configured to form a first portion of a first cooling circuit (1180), the first branch having a first joining surface (1078a), and a second core body (1070b) having a second trunk (1072b) configured to attach to a second location of a cavity core structure, a first branch (1074b) of the second core body extending from the second trunk and configured to form a first portion of a second cooling circuit (1182) in the component. The first branches of the core bodies joined to form a junction (1164). The junction defines a merger of the first cooling circuit and the second cooling circuit proximate to an exit of the first and second cooling circuits.
    • 用于制造燃气涡轮发动机(20)的部件的核心组件和方法包括:第一核心主体(1070a),其具有被配置为附着到空腔核心结构的第一位置的第一主干(1072a);第一分支(1074a) 所述第一树干并且被配置为形成第一冷却回路(1180)的第一部分,所述第一分支具有第一接合表面(1078a),所述第二芯体(1070b)具有第二树干(1072b),所述第二树干构造成附接到 腔芯结构的第二位置,所述第二芯体的第一分支(1074b)从所述第二主干延伸并且构造成在所述部件中形成第二冷却回路(1182)的第一部分。 核心体的第一分支连接形成一个连接点(1164)。 该接合处限定第一冷却回路和第二冷却回路的合并,靠近第一和第二冷却回路的出口。
