    Abstract: PROBLEM TO BE SOLVED: To provide an air bleeding system utilizing the tangential velocity component of the air flowing out from a rear edge of an upstream blade. SOLUTION: This air bleeding system used in a gas turbine engine, comprises a plurality of vanes (blades) 10, and each vane 10 has an air foil member 14 and a platform structural body 16. This air bleeding system has a passage between blades, formed by the adjacent air foil member 14 and an end wall formed by the platform structural body 16. A bleeding hole 30 is formed in the passage between blades, and the fluid partially bleeds therefrom. The positioning of a bleeding part in the axial direction and the circumferential direction in a channel of a stator is determined to obtain the optimum balance of the static pressure and the tangential velocity.

    Abstract: A gas turbine engine includes a buffer system that can communicate a buffer supply air to a portion of the gas turbine engine. The buffer system includes a first bleed air supply having a first pressure, a second bleed air supply having a second pressure that is greater than the first pressure, and an ejector that selectively augments the first bleed air supply to prepare the buffer supply air for communication to the portion of the gas turbine engine.

    Abstract: A gas turbine engine (20) includes a buffer system (60; 160; 260) that communicates a buffer supply air (62; 162; 262A, 262B) to a portion of the gas turbine engine (20). The buffer system (60; 160; 260) includes a first bleed air supply (64; 164; 264A, 264B) having a first pressure, a second bleed air supply (66; 166; 266A, 266B) having a second pressure that is greater than the first pressure, and a valve that selects between the first bleed air supply (64; 164; 264A, 264B) and the second bleed air supply (66; 166; 266A, 266B) to communicate the buffer supply air (62; 162; 262A, 262B) to the portion of the gas turbine engine (20).
