Abstract: A rotor blade includes an airfoil having a tip plate that extends across an outer radial end. A rim extends radially outward from the tip plate and surrounds at least a portion of the airfoil and includes a concave portion opposed to a convex portion. A plurality of dividers extend between the concave and convex portions to define a plurality of pockets between the concave and convex portions at the outer radial end. A plurality of cooling passages through the tip plate provide fluid communication through the tip plate to the plurality of pockets. A first fluid passage in at least one divider provides fluid communication between adjacent pockets across the at least one divider.

Abstract translation: 转子叶片包括具有延伸穿过外径向端的顶板的翼型件。 边缘从顶板径向向外延伸并且包围翼型的至少一部分并且包括与凸部相对的凹部。 多个分隔件在凹部和凸部之间延伸以在外径向端部处在凹部和凸部之间限定多个凹穴。 通过顶板的多个冷却通道提供通过顶板到多个凹穴的流体连通。 至少一个分隔器中的第一流体通道提供穿过至少一个分隔器的相邻袋之间的流体连通。
