Turbomachine having an annular combustion chamber

Abstract

A turbomachine including an annular combustion chamber, the combustion chamber presenting a connection flange at its downstream end for connection to an outer casing. The connection flange bears axially against the outer casing and is blocked in an axial direction by the upstream end of an inner casing of a high pressure turbine.

1 - 8 . (canceled) 
     
     
         9 . A turbomachine comprising:
 an annular combustion chamber, the combustion chamber presenting a connection flange at its downstream end for connection to an outer casing,   wherein the connection flange bears axially against the outer casing and is blocked in an axial direction by the upstream end of an inner casing of a high pressure turbine, the connection flange of the combustion chamber and the upstream end of the inner casing of the turbine bearing radially against the outer casing.   
     
     
         10 . A turbomachine according to  claim 9 , wherein the upstream face of the connection flange includes an annular setback having a cylindrical face and a radial face that bear respectively against a cylindrical face and a radial face of the inner annular surface of the outer casing. 
     
     
         11 . A turbomachine according to  claim 9 , wherein the upstream end of the inner casing of the turbine has a cylindrical face bearing radially against an inner cylindrical surface of the outer casing. 
     
     
         12 . A turbomachine according to  claim 10 , wherein the end of the connection flange comprises a cylindrical portion that extends axially between the radial face of the annular setback of the outer casing and the upstream end of the inner casing of the turbine. 
     
     
         13 . A turbomachine according to  claim 12 , wherein the combustion chamber and the inner casing of the turbine are mounted inside the outer casing from downstream, with radial clearance while cold between the downstream end of the connection flange and the upstream end of the inner casing of the turbine. 
     
     
         14 . A turbomachine according to  claim 9 , wherein the outer casing is continuous between an upstream flange situated at the upstream end of the combustion chamber and a downstream flange situated at the downstream end of the inner casing of the high pressure turbine. 
     
     
         15 . A turbomachine according to  claim 9 , wherein the connection flange includes a bent portion that is elastically deformable in a radial direction. 
     
     
         16 . A turbomachine according to  claim 9 , wherein the inner casing of the turbine is fastened at its downstream end to the outer casing via a bolted connection.
