摘要： In a turbomachine in which the stator includes at least one stage of pivole blades and a ring which is movable axially to operate the levers which rotate the blades, the ring is moved by varying the pressure of gas which is contained in sealed chambers and which exerts a force between the movable ring and another fixed ring. This arrangement enables a better distribution of the forces to be achieved than purely mechanical movement control systems.

摘要： A stemmed blade for flow-straightener blading of a gas turbine engine includes at least one shank at the head of the blade forming a stem for use in fixing the blade. The shank has a notched portion situated adjacent the head of the blade and an end portion separated from the notched portion by a zone of lower tensile strength. Fixing of the blade to the engine casing is carried out by fitting the blade in position with the shank projecting radially outwards through a hole in the casing and then crimping a bush on to the notched portion of the shank using a suitable crimping tool which exerts a compressive force on the bush while exerting a traction force on the end of the shank until the zone of lower tensile strength breaks.

摘要： A gas turbine compressor casing has two inner and outer envelopes forming at least one closed cavity and a locking or clamping ring having a thermal inertia higher than that of the envelopes and mounted in the closed cavity in such a way as to limit its contraction during a lowering of the temperature. The thermal inertia difference can be obtained by using for the locking ring a material having a thermal expansion coefficient lower than the coefficient of the envelopes. It can also be controlled by a ventilation means device for ensuring hot air flow in the cavity.

摘要： A turbine engine stator has a metal casing surrounding an envelope carrying bearings for the pivots of pivoting blades. A control mechanism for setting the position of the blades includes a radial spindle to which are transmitted the thrust forces of the gases, the envelope being advantageously formed from angular sectors of axially juxtaposed flanges or rings and which are not loaded. Therefore, the bearings are not subject to wear giving rise to gas leaks and efficiency losses. Advantageously, the envelope is made from a composite material.

摘要： A turbjet engine includes various elements for adjustment of play of the stator by having the stator heated or cooled by a gas. The outer housing to which the ferrule bearing the fixed vane stages is secured may be formed of two skins between which the gas is injected. The ferrule may be composed of sectors extending over one circumference fraction and fixed via their center and simply guided at their extremity; finally, it is possible to provide sealing devices between the outer housing and the support bearing surfaces of the ribs of the ferrule elements. The volume between the ferrule and the housing is then sectioned and is able to receive separate gas feedings for play adjustment.

摘要： A fan or compressor stage rotor comprises a disc, radial blades mounted in axial sockets formed in the periphery of the disc, and spacer blocks interposed between the blades to constitute the inner boundary of the air flow path through the rotor. The spacer blocks each comprise an outer wall which is spaced from the periphery of the disc, and front and rear walls extending radially inwardly to overlap at least partially the front and rear faces of the disc. The front and rear walls each comprise at least one hook which co-operates with a corresponding groove provided in the respective face of the disc to fix the spacer block to the disc. The spacer block also comprises a median partition projecting inwards from its outer wall and having a slot through which passes a leaf spring of a vibration damper.

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.
