Patent number: 6655912Abstract: The present invention relates to a guide vane stage of a compressor comprising an outer ring and an inner ring, which are both concentric and preferably circular. The rings are connected to each other via a series of fixed vanes, and are characterized in that at least the inner ring is provided with holes or apertures which allows one of the ends of the vanes to pass through these holes or apertures. The vanes also have at their end a second aperture intended to allow the passage of a retaining and rigidifying component having an elastic function, in order to hold them in pairs.Type: GrantFiled: November 30, 2001Date of Patent: December 2, 2003Assignee: Techspace Aero S.A.Inventor: Mathieu Bos

Patent number: 6595747Abstract: A guide vane stage of a compressor comprising an outer ring and an inner ring, both of which are concentric and preferably circular is provided. The rings are connected to each other via a series of fixed vanes, characterized in that at least one of the rings is provided with a series of holes or apertures which allow the vanes to pass through these holes or apertures. The fixed vanes also have, at at least one of their ends, an aperture to allow at least one locking element to pass through, making it possible to simultaneously securely fasten all the present in the guide vane stage, on the non-functional side of the ring. The end of the fixed vanes through which the locking element passes is buried in an elastomeric element.Type: GrantFiled: November 30, 2001Date of Patent: July 22, 2003Assignee: Techspace Aero S.A.Inventor: Mathieu Bos

Patent number: 6543818Abstract: The present invention relates to an axisymmetric structural component, one of the ends of which is fitted with an inner circular flange for assembling, by bolting. The axisymmetric structural component with a second axisymmetric structural component. The flange comprises housings for receiving fixing elements such as bolts, pins or threaded rods. The housings are arranged on the circumference of the said flange at regular intervals. Each housing is, in longitudinal section (A—A) along a plane passing through the rotational axis of the component, T-shaped and consists of a first essentially cylindrical portion which is longitudinally open on the inner face (x) of the axisymmetric structural component and transversely open on the contact face (y) of the flange in the assembly. A second essentially semi-cylindrical portion is mounted on the flange which is also longitudinally open on the inner face (x) of the said structural component having an essentially D-shaped transverse section.Type: GrantFiled: May 30, 2001Date of Patent: April 8, 2003Assignees: Techspace Aero S.A., Snecma MoteursInventors: Frédéric Leman, Guy Vieillefond, Mathieu Bos, Sébastien Ryhon
