    • An internally cooled airfoil comprises an airfoil body, a baffle and a plurality of standoffs. The airfoil body is shaped to form leading and trailing edges, and pressure and suction sides surrounding an internal cooling channel. The baffle is disposed within the internal cooling channel and comprises a liner body having a perimeter shaped to correspond to the shape of the internal cooling channel and to form a cooling air supply duct. The baffle includes a plurality of cooling holes extending through the liner body to direct cooling air from the supply duct into the internal cooling channel. The standoffs maintain minimum spacing between the liner body and the airfoil body. In one embodiment, the standoffs are recessed into a surface of either the baffle or the airfoil body. In another embodiment, the standoffs are elongated to meter flow between the liner body and the airfoil body.
    • 内部冷却的翼型件包括翼型本体,挡板和多个支座。 翼型体成形为形成前缘和后缘,围绕内部冷却通道的压力和吸力侧。 挡板设置在内部冷却通道内,并且包括衬套主体,其具有成形为对应于内部冷却通道的形状的周边并且形成冷却空气供应管道。 挡板包括多个冷却孔,其延伸穿过衬套主体,以将冷却空气从供应管道引导到内部冷却通道中。 支架保持衬套主体和翼型体之间的最小间距。 在一个实施例中,支座凹入到挡板或翼型体的表面中。 在另一个实施例中,支座是伸长的,用于测量衬套主体和翼型体之间的流量。

    • Disclosed are examples of flow-directing elements, airfoil inserts, and assemblies thereof. A flow-directing element has an inner buttress with an airfoil extending outwardly therefrom. The airfoil includes a cavity that extends within the airfoil to an exit port disposed in the inner buttress. A shelf disposed about the buttress defines the exit port, and the shelf includes a discourager extending into the cavity. An airfoil insert has a tubular body, with an outlet at one end. A plate affixed to the body at the outlet partially blocks the outlet, and includes a tab extending away from the body and defining a portion of an outlet periphery. Upon assembly of the flow directing element and the insert, the tab interacts with the discourager to direct a coolant to the exit port while restricting leakage of the coolant back into the cavity, between the airfoil insert and the flow-directing element.
