POROUS LAMINATED COMBUSTOR STRUCTURE Abstract of the Disclosure A combustor assembly for a gas turbine engine includes a tubular, multi-layered porous metal wall with pores and cavities for distribution of compressor discharge air into a combustion chamber and wherein a rigid combustor support ring connects one end of the porous wall to fixed support components of the gas turbine engine; the combustor assembly further including a porous metal transition member for joining the tubular porous metal wall to a downstream nozzle plate; the transition member including free formed side walls and top and bottom walls without substantial reduction in permeability due to forming and each of the transition walls further including a sharp radius bend at the side edge thereof defining a compressed porous metal section for connection to an adjacent sharp radius bend by means of a longitudinal seam weld along the length thereof to maximize the flow of secondary cooling air into the hot combustion gases passing from the outlet of the combustion chamber of the apparatus.
