Abstract: PROBLEM TO BE SOLVED: To provide a seal assembly for restricting leaking-out of cooling air in constant. SOLUTION: An inside cavity 50 is positioned between a vane support part 52 and a rotary assembly 54 on the inside in the radial direction of an annular duct 30. The cooling air 40 is introduced into the cavity 50 by a duct 70, and cools a blade 58 by flowing in a conduit 72. The cavity 50 is separated from the duct 30 by a seal 80, and air pressure is properly maintained over the whole engine conditions. A segment-like ring 86 extends by crossing the cavity 50 from a divided rim area 110, and a runner 170 is aligned with land 84. One complete segment-like ring 86 is formed by aligning a plurality of adjacent ring segments 164 and 166 in a state of inserting the blade 58 into a disc. Leaking-out restriction is improved by extending the runner 170 outside or inside in the radial direction from the ring 86 by inclining to a shaft 11. COPYRIGHT: (C)2007,JPO&INPIT

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 at least one land, and an interrupted rim region of a bladed rotor assembly defines at least one segmented ring. The at least one segmented ring protruding outward from the bladed rotor assembly in the interrupted rim region, spans across the cavity and cooperates with the at least one land to define a seal.

Abstract: A disclosed gas turbine engine includes a case for a case for a compressor section including a bleed air slot. The bleed air slot includes an inlet having a first area radially inward of an outlet having a second area with the second area being greater than the first area. The bleed air slot further includes a center portion disposed along a radial line extending from an axis of the engine and an elongated portion extending from the opening at an angle relative to a line normal to the radial line.
