  • Airtight external shroud for a turbomachine turbine wheel
    Patent number: 8177493
    Abstract: External shroud for a turbomachine turbine wheel, this shroud being formed of ring sectors (120) positioned circumferentially end to end, and each comprising a circumferentially directed plate (136) bearing a block (138) of abradable material, the plate and the block of each ring sector being offset one with respect to the other in the circumferential direction so that a circumferential end part of the plate of each ring sector overlaps a corresponding end part of the block of an adjacent ring sector.
    Type: Grant
    Filed: March 19, 2008
    Date of Patent: May 15, 2012
    Assignee: SNECMA

  • Arrangement for the attachment of distributor sectors supporting vanes around an arc of a circle
    Publication number: 20030146578
    Abstract: Distributor sectors (25) on which fixed vanes are placed adjacent to a casing (31) by means of sealing sectors (32) alternating with them in the axial direction and provided with force resistant faces (37; 39) through which forces exerted on the distributor sectors are transmitted to the casing. The inner surface of the casing (31) is smoother and is not fitted with any hooks; consequently, this casing (31) is less complicated to make and is less mechanically stressed to retain the distributor sectors, and the distributor sectors may be installed by a purely axial movement.
