Abstract: An airfoil portion including an outer wall that defines a cavity for receiving cooling air. The airfoil portion includes a leading edge that resides in an upstream direction, a trailing edge that resides in a downstream direction, a convex suction side, and a concave pressure side. At least one insert disposed within the cavity is configured to initially receive at least a portion of the cooling air entering the chamber of the insert and direct the cooling air through a plurality of insert apertures to cool the inner surface of the outer wall of the airfoil portion. The insert further includes a configuration that generally conforms to the contour of the outer wall of the chamber but in spaced relation thereto. A portion of the cooling air exits the airfoil portion through a plurality of film cooling apertures formed through the outer wall. A main insert includes at least one additional insert which is inserted from the outside and transferred into the cavity at an intermediate position, and then moved in direction to the trailing edge and fixed to predetermined position The additional insert forms the size of the trailing edge channel inlet at the end of the main insert.

Abstract: The disclosure pertains to a vane comprising a platform and airfoil extending form said platform and connected to the platform by a fillet. An impingement tube is inserted into said airfoil delimiting a cooling channel between the impingement tube and the side walls. The vane further comprises a baffle structure positioned adjacent the fillet and which follows the inside contour of the fillet; delimiting a first cooling passage between the fillet and the baffle structure. A first obstruction is arranged on the inside of the airfoil at the connection of the fillet to the side walls for separating the first cooling passage from the cooling channel in the airfoil and to guide the cooling gas from the first cooling passage into the impingement tube. The disclosure further refers to a method for cooling such a vane.

Abstract translation: 本公开涉及一种叶片，其包括从所述平台延伸并且通过圆角连接到平台的平台和翼型件。 冲击管被插入到限定冲击管和侧壁之间的冷却通道的所述翼型件中。 所述叶片还包括邻近所述圆角定位并且跟随所述圆角的内部轮廓的挡板结构; 限定圆角和挡板结构之间的第一冷却通道。 在翼片与侧壁的连接处，在翼型件的内部设置第一障碍物，用于将第一冷却通道与翼型中的冷却通道分离，并将冷却气体从第一冷却通道引导到冲击管中。 本发明还涉及冷却这种叶片的方法。
