Patent number: 9188013Abstract: A turbine engine turbine blade of ceramic matrix composite. The root of the blade includes a single densified fiber preform including at least one recess made by machining, each point of the root of the blade being situated at a distance from a free surface of the root that is no greater than twice the maximum penetration distance into the preform of densification gas for densifying the preform, and the distal portion of the root of the blade includes a distal wall that is continuous and in a single piece.Type: GrantFiled: December 8, 2010Date of Patent: November 17, 2015Assignees: SNECMA, HERAKLESInventors: Son Le Hong, Jean-Luc Soupizon, Nicolas Christian Triconnet, Nicolas Eberling-Fux, Clement Roussille

Patent number: 8573944Abstract: An anti-wear device of a turbomachine rotor including a disk with a rim and axial recesses machined on the rim for the individual housing of blades; and a ring being fitted to one face of the rim, the ring being pierced with holes in the axial extension of the recesses, is disclosed. At least one of the holes in the extension of the recesses is closed by a plug including a metal head forming a bearing surface for the blades. The plug includes a stud in the extension of the metal head, an insert made of deformable material surrounding at least partly the stud, and a clamping device. The insert is made of deformable material being deformed by the clamping device so as to immobilize the plug in the hole.Type: GrantFiled: July 28, 2010Date of Patent: November 5, 2013Assignee: SNECMAInventors: Michael Delapierre, Jerome Paul Marceau Mace, Patrick Jean-Louis Reghezza, Nicolas Christian Triconnet

Patent number: 8162602Abstract: A cylindrical casing for a turbomachine that is suitable for receiving a rotor fitted with at least one bladed wheel is disclosed. The casing includes a device for preventing instability during contact between the casing and the bladed wheel. The device includes a succession of elements disposed around the circumference of the casing, and presenting different stiffnesses between two adjacent elements. The number of elements having the same stiffness not being equal to a multiple of the wave number of the vibratory mode of the bladed wheel that is to be inhibited. The invention is applicable to a compressor, a turbine, or a fan.Type: GrantFiled: April 22, 2009Date of Patent: April 24, 2012Assignee: SNECMAInventors: Mathieu Caucheteux, Francois Maurice Garcin, Jean-Pierre Francois Lombard, Nicolas Christian Triconnet

Patent number: 8128352Abstract: The invention relates to a turbomachine thermomechanical part forming a body of revolution about a longitudinal axis, and including at least one abradable ring for a labyrinth seal. In characteristic manner, the abradable ring is made up of angular sectors that present different stiffnesses between adjacent pairs of sectors. The invention is applicable to a compressor, a turbine, or to a rotor and stator assembly.Type: GrantFiled: April 23, 2009Date of Patent: March 6, 2012Assignee: SNECMAInventors: Mathieu Caucheteux, Francois Maurice Garcin, Jean-Pierre Francois Lombard, Nicolas Christian Triconnet

Patent number: 8038403Abstract: A turbomachine rotor wheel includes a disk carrying blades having roots engaged and held in an annular recess of the disk. The roots are connected to platforms for co-operating with an annular gasket mounted in an annular groove of the disk. The annular sealing gasket exerts a resilient force on the blade platforms holding the blades in a proper position for operation while the turbomachine is at rest.Type: GrantFiled: February 2, 2007Date of Patent: October 18, 2011Assignee: SNECMAInventors: Claude Robert Louis Lejars, Nicolas Christian Triconnet, Frederick Thise
