    摘要: In a turbomachine, such as a turboshaft aero-engine, having a compressor casing composed of upstream and downstream casing rings, and a variably settable stage of stator blades which is mounted in one of said casing rings near the junction therebetween so that, in normal operation, the blades have their leading (or trailing) edges projecting into the other casing ring, the setting of the blades being adjusted by a control ring surrounding the casing, there is provided a locking system for temporarily locking the blades in an angular setting in which the leading (or trailing) edges are retracted clear of said other casing when the casing is to be dismantled or assembled. The locking system comprises at least one locking member which is held captive on one of the screws securing the two casing rings together, the member being movable in the axial direction by the screw and having axially extending wings which engage in slots in the control ring to effect the locking of the stator blades when the screw is unscrewed.

    摘要: The casing of a turboshaft engine, particularly a turbojet engine with a high speed propeller, comprises axially successive shells which are fixed firmly to each other end to end by bolted coupling flanges, at least one of the shells comprising an additional mechanical axial retaining joint enabling the connection between the shells to withstand any exceptional stresses such as those caused by the loss of a propeller blade of the turbojet engine. Preferably the retaining joint comprises a radially inwardly directed tongue carried by one of the shells and received in a radially outwardly open groove provided in a portion of the other shell or a member securely fixed thereto.

    摘要: A device for locking the blade roots (3) in rotor disk alveoli (2) consists of a single split ring (9) with a Y shaped cross-section of which a radial upstream arm (9a) is inserted in the groove (7) of the downstream blade lips (6) the radial downstream arm (9b) of the ring (9) being pressed against the downstream part of the blade lips (6).
