Combustor liner stop

Abstract

A combustion liner includes a substantially cylindrical body having forward and aft ends, the forward end provided with plural, circumferentially-shaped stops adapted for connection to a flow sleeve surrounding the substantially cylindrical body. Each stop includes a radially-projecting strut having an end remote from the substantially-cylindrical body provided with a tab having a shape different than the strut. Each strut is received in a slot formed in the flow sleeve, with the tab on an exterior surface of the flow sleeve.

What is claimed is: 
     
         1 . A combustion liner comprising:
 a substantially cylindrical body having forward and aft ends, the forward end provided with plural, circumferentially-shaped stops adapted for connection to a flow sleeve surrounding said substantially cylindrical body, each stop comprised of a radially-projecting strut having an end remote from the substantially-cylindrical body provided with a tab having a shape different than said strut.   
     
     
         2 . The combustion liner of  claim 1  wherein said strut is substantially airfoil-shaped. 
     
     
         3 . The combustion liner of  claim 1  wherein said strut is slanted toward said aft end of said substantially-cylindrical body. 
     
     
         4 . The combustion liner of  claim 1  wherein said tab is formed to have an elongated, substantially-rectangular block shape. 
     
     
         5 . The combustion liner of  claim 1  wherein said plural, circumferentially-spaced stops comprise three stops substantially equally-spaced about a circumference of said substantially cylindrical body. 
     
     
         6 . The combustion liner of  claim 2  wherein said strut is slanted toward said aft end of said substantially-cylindrical body. 
     
     
         7 . The combustion liner of  claim 6  wherein said plural, circumferentially-spaced stops comprise three stops substantially equally-spaced about a circumference of said substantially cylindrical body. 
     
     
         8 . A combustor liner and flow sleeve assembly comprising:
 a combustor liner having an aft end and a forward end;   a flow sleeve surrounding said combustor liner and defining an axially-extending, annular flow passage radially therebetween, the flow sleeve provided with plural slots at a forward end thereof; the combustor liner provided with plural, circumferentially-spaced struts extending radially outwardly and through respective ones of said plural slots in said flow sleeve; each of said plural circumferentially-spaced struts provided with a tab that lies on an exterior surface of said flow sleeve outside said annular flow passage.   
     
     
         9 . The combustor liner and flow sleeve assembly of  claim 8  wherein each of said plural circumferentially-spaced struts is substantially airfoil-shaped. 
     
     
         10 . The combustion liner and flow sleeve assembly of  claim 8  wherein each of said plural circumferentially-spaced struts is slanted toward said aft end of said substantially-cylindrical body. 
     
     
         11 . The combustion liner and flow sleeve assembly of  claim 8  wherein said tab is formed to have an elongated, substantially-rectangular block shape. 
     
     
         12 . The combustion liner and flow sleeve assembly of  claim 8  wherein said plural, circumferentially-spaced struts comprise three struts substantially equally-spaced about a circumference of said substantially cylindrical body. 
     
     
         13 . The combustion liner and flow sleeve assembly of  claim 9  wherein each of said plural circumferentially-spaced struts is slanted toward said aft end of said substantially-cylindrical body. 
     
     
         14 . The combustion liner and flow sleeve assembly of  claim 13  wherein said plural, circumferentially-spaced struts comprise three struts substantially equally-spaced about a circumference of said substantially cylindrical body. 
     
     
         15 . The combustion liner and flow sleeve and flow sleeve assembly of  claim 8  wherein said plural slots are substantially rectangular, with open ends at said forward end of said flow sleeve. 
     
     
         16 . The combustion liner and flow sleeve assembly of  claim 15  wherein after assembly, said plural slots are closed at said open ends by an annular ring attached to the forward end of said flow sleeve. 
     
     
         17 . A combustor liner and flow sleeve assembly comprising:
 a combustor liner having an aft end and a forward end; and   a flow sleeve surrounding said combustor liner and defining an axially-extending flow passage radially therebetween, the flow sleeve provided with plural slots at a forward end thereof; wherein the combustor liner is provided with plural, circumferentially-spaced airfoil-shaped struts slanted toward said aft end of said substantially-cylindrical body and extending radially outwardly and through respective ones of said plural slots in said flow sleeve; each of said plural circumferentially-spaced struts provided with a remote tab having a shape different than that strut, and wherein said tab lies on an exterior surface of said flow sleeve.   
     
     
         18 . The combustion liner and flow sleeve assembly of  claim 17  wherein said tab is formed to have an elongated, substantially-rectangular block shape. 
     
     
         19 . The combustion liner and flow sleeve assembly of  claim 17  wherein said plural, circumferentially-spaced struts comprise three struts substantially equally-spaced about a circumference of said substantially cylindrical body. 
     
     
         20 . The combustion liner and flow sleeve assembly of  claim 17  wherein said plural slots have open ends at said forward end of said flow sleeve and, after assembly, said plural slots are closed at said open ends by a single or plural closure parts, attached to the combustor casing or forward end of the flow sleeve.
