    摘要： A turbine engine component includes a wall, a main opening, and two clusters of two or more auxiliary openings. The wall includes cool and hot air sides. The main opening extends between the cool air side and the hot air side and has an inlet and an outlet. The inlet is formed on the cool air side, and the outlet is formed on the hot air side. The first cluster of two or more auxiliary openings extends from the main opening to the hot air side. The second cluster of two or more auxiliary openings extends from the main opening to the hot air side. The main opening may be cylindrical or conical with a converging passage extending from the cool air side to the hot air side. The converging main opening may enhance flow through the auxiliary openings especially at high blowing ratios.

    摘要翻译： 涡轮发动机部件包括壁，主开口和两个或更多个辅助开口的两个簇。 墙壁包括凉爽和热的空气两侧。 主开口在冷空气侧和热空气侧之间延伸并具有入口和出口。 入口形成在冷空气侧，出口形成在热空气侧。 两个或更多个辅助开口的第一簇从主开口延伸到热空气侧。 两个或更多个辅助开口的第二组从主开口延伸到热空气侧。 主开口可以是圆柱形或圆锥形的，具有从冷空气侧延伸到热空气侧的会聚通道。 会聚主开口可以增强通过辅助开口的流动，特别是在高吹风比下。

    摘要： A turbine section of a gas turbine engine is annular about a longitudinal axis. The turbine section includes a first turbine with a first inlet and a first outlet; a second turbine with a second inlet and a second outlet; and an inter-turbine duct extending from the first outlet to the second inlet and configured to direct an air flow from the first turbine to the second turbine. The inter-turbine duct has a first station with a first meridional area, a second station with a second meridional area, and a third station with a third meridional area. The first station is upstream of the second station and the second station is upstream of the third station, and the second meridional area is less than or equal to the first meridional area.
