A gas turbine engine combustor assembly has an outer annular porous laminated wall and an inner annular porous laminated wall joined at one end thereof by an annular load support dome plate that closes one end of the combustor; peripheral extensions on the inlet end of each of the inner and outer walls are directed outwardly of a combustion zone to define a flame isolated connection surface on both of the laminated walls of the combustor and wherein connection means are provided to connect the dome plate to the connection surface to define inner and outer annular sealed joints at the combustor dome without blockage of coolant flow through the inner and outer porous laminated walls to maintain full cooling of the flame exposed inner surfaces of the inner and outer laminated walls and wherein the connection means are maintained out of direct flame exposed relationship with an interior combustion zone within the combustor.

A gas turbine engine combustor assembly located in an inlet air plenum comprising: an outer annular porous laminated wall, an inner annular porous laminated wall aligned with said outer wall to define a fuel combustion zone therebetween having opposite open ends, an annular porous laminated wall dome plate closing one of said open ends, an extension of porous laminated wall on the inlet end of each of said inner and outer annular walls, said extension being directed outwardly of the combustion zone to define a flame isolated connection surface on both the inner and outer laminated walls of the combustor at a point exposed to inlet plenum air, said dome plate having spaced, bent porous flanges thereon, and connection weld means connecting said dome plate flanges to said connection surfaces to define an annular sealed weld joint at said connection surfaces to close said one open end whereby coolant flow from exteriorly of the combustor assembly is free to flow across the full flamed exposed inner wall surfaces of the inner and outer wall and dome exposed to the combustion zone and wherein the connection means between said inner and outer walls and dome plate flanges is maintained out of direct flame exposed relationship with the combustion zone and in direct coolant flow relationship with inlet plenum air for maintenance of a secure, cool, thermal fatigue resistant connection between the annular dome plate and the inner and outer walls of the combustor assembly.
