    摘要: A connection device is disclosed for connecting a burner ring or flame holder made of a composite material and having a "V"-shaped cross-section, to an afterburner chamber duct of a turbojet engine. The connecting device has a cylindrical portion and a trapezoidal portion. The cylindrical portion extends through hollow projections formed from the composite ring material and extending from the ring in an upstream direction. The converging, opposite sides of the trapezoidal portion bear against inner surfaces of the converging flanges forming the "V" cross-section of the ring. The cylindrical portion is then attached to the afterburner duct via a link-bar mechanism.

    摘要: A turbojet engine has an outlet duct to which an annular array of actuating cylinders for nozzle flaps are hinged. The housings for the cylinders are connected together by transverse members to form a rigid structure coaxial with the outlet duct. The arrangement includes convergent flaps and slaving devices for divergent flaps, all hinged to the rigid structure and particularly to the housings.

    摘要: Convergent flaps of a jet engine nozzle are controlled by actuating cylinders through actuating levers hinged to the fixed structure of the engine and by connecting rods. Divergent flaps are slaved to the convergent flaps by connecting rods themselves driven by the actuating levers. Cold flaps not hinged to the divergent flaps are slaved to the convergent flaps by further connecting rods connected to the first-named connecting rods.

    摘要: A ring of an annular valve assembly is movable in the direction of its longitudinal axis and is intended for an axial compressor blow-off arrangement. The ring takes the form of an axially orientated channel-section member having a first annular skin of concave section nested in a second annular skin also of concave section. A cavity filled with a synthetic resin filler is defined by the two skins. The blow-off arrangement for an axial-flow compressor of a turbo-jet engine, which incorporates this ring, comprises an annular opening with which the ring cooperates to re-form the wall of the air flow when the blow-off arrangement is inoperative.

    摘要: The rotor of each stage of a turbine is surrounded, with a clearance by a fixed ring, formed by a metal ring supporting internally an annular thermal screen, in the form of ceramic segments. Expansions and contractions of the metal ring under the action of air which is supplied thereto in order to control the said clearance are transformed into displacements of radial faces of the ring in contact with radial flanges rigid with the turbine casing and seals serve to ensure fluidtightness of the ring.

    摘要: A device for attaching the stator vanes of an axial compressor to an external housing is disclosed. The attachment utilizes an inner casing, having the vanes mounted on it, and an outer casing surrounding the inner casing in such a manner that differential thermal expansion between the various elements is minimized. This allows more accurate control of the clearances between the rotor and the stator.
