    Abstract: A gas turbine engine (20) having a turbine section cooling system is disclosed which is able to cool the turbine section (26) of the g as turbine engine (20) to an optimal operating temperature range, while at the same time not substantially degrading engine performance. The disclosure provides a number of different structures for doing so including the provision of turning foils (44), turning holes (54), and turning grooves within a secondary air flow cavity which turns or directs cooling and parasitic leakage air into the turbine section (26) in a direction in substantial alignment with a gas flow path through the turbine section (26).

    Abstract: A system is disclosed for injecting a secondary fluid stream (42) into a primary fluid stream (28) with improved aerodynamic efficiency. The secondary fluid stream (42) is injected into the primary fluid stream (28) at a tangential angle and radial location that reduces both mixing and endwall losses. A platform (44) borders the primary fluid stream (28) and contains a trailing edge surface (68). A rail (80) extends radially from the platform (44) and one or more conduits (80) enter the rail (80) in a substantially radial direction. The conduits (82) extend through the radial length of the rail (80), continue into the platform (44), and terminate at the trailing edge surface (68). The secondary fluid stream (48) is conveyed by the conduits (82) through the rail (80) and the platform (44), to the trailing edge surface (68), for injecting into the primary fluid stream (28) at an optimal angle and radial location.

    Abstract: Disclosed are assemblies and articles for restricting leakage of a pressurized fluid from a cavity. In accordance with an embodiment of the invention, a vane support defines a land, and a neck region of a bladed rotor assembly defines a segmented ring. The segmented ring protrudes outward from the bladed rotor assembly in the neck region, spans across the cavity and cooperates with the land to define a seal.
