    摘要: Retaining structure for a turbo-machine forming an annulus having a complexircumferential construction comprising a cylindrical sector of a high mechanical strength material protecting a member secured on the casing of the machine. The complementary sector of the annulus is a honeycomb structure mounted between an internal and an external skin. The cylindrical sector is formed by a thickening of the internal skin. A strap of a material with a high elastic modulus serves to secure at least the complementary sector.

    摘要: In a multi-spool turbo machine, a first shaft of the low pressure spool is supported for rotation with respect to a second shaft of the high pressure spool and is located with respect to the second shaft by means of a roller bearing. Rollers of the bearing are inserted between an internal ring mounted on the second shaft and an outer ring mounted by a ring support assembly carried by the first shaft. The ring support assembly includes a ring support member which comprises, at its outer periphery, a first toothed element cooperating with a second toothed element carried by retaining means. The ring support member is held axially by a channel-section member.

    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.
