    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: An anti-rotation lock (61) for preventing circumferential movement of a stator segment (30) in relation to a split case (32) to which it is mounted is disclosed. A racetrack shaped pocket (62), disposed within the case (32) and proximate the stator segment (30), is suitably sized to receive a lug (64) and a spring pin (66). The lug (64) is received in the pocket (62) and protrudes radially inward from the case (32) and is engagable by the stator segment (30), thus preventing circumferential movement with respect to the case (34). The spring pin (66) is received adjacent to the lug (64) and compressively retains the lug (64) in the pocket (62).
