Combustor construction

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.
