Patent number: 11971174Abstract: A turbomachine has the upstream portion of the annular combustion chamber is fixed to the outer housing via individual pins with a swivel connection. The swivel connection is established between the pin and a part of the outer housing. The pin is slidable radially, or with a radial component, by a slide established between the pin and a tubular part of the outer annular shroud and/or the annular wall of the chamber bottom.Type: GrantFiled: May 14, 2020Date of Patent: April 30, 2024Assignee: SAFRAN AIRCRAFT ENGINESInventors: Dan-Ranjiv Joory, Jacques Marcel Arthur Bunel, Benjamin Frantz Karl Villenave

Patent number: 11808456Abstract: A combustion chamber includes a bottom wall having at least one opening, at least one sleeve mounted upstream of the bottom wall and fixed to the bottom wall, a closing ring defining an annular groove with the sleeve and fixed to the sleeve, and at least one air and fuel injection system having an axis, mounted in the opening of the bottom wall. The injection system has an annular flange extending radially with respect to the axis and is mounted in the groove with radial clearance. A baffle is situated downstream of the bottom wall and is fixed to the sleeve and/or to the bottom wall.Type: GrantFiled: February 19, 2020Date of Patent: November 7, 2023Assignee: SAFRAN AIRCRAFT ENGINESInventors: Jacques Marcel Arthur Bunel, William Louis Rodolphe Dousse, Benjamin Frantz Karl Villenave

Patent number: 11085640Abstract: A method for producing an annular combustion chamber of a turbojet using CMC. For this, a shaping tool with movable slides is used and said chamber is produced around the tool, thereby producing a fibrous preform of which the shape is consolidated by drape moulding on the tool and pyrolysis, which is then densified by CVI. Several slides have back drafts, at least one other of such slides having a draft or neither a draft nor a back draft. Then, the slides are removed in a predetermined order imposed by the back drafts and the relative positions of the slides.Type: GrantFiled: July 24, 2019Date of Patent: August 10, 2021Assignee: Sanfran Aircraft EnginesInventors: Jacques Marcel Arthur Bunel, William Louis Rodolphe Dousse, Dan Ranjiv Joory, Benjamin Frantz Karl Villenave
