Abstract
A combustor apparatus for use in gas turbine engines includes an annular dome of porous laminated material joined by a solid metal joint ring to inner and outer annular porous wall segments also constructed of porous laminated material; and wherein the solid metal joint ring includes a plurality of small diameter offset effusion holes for directing coolant through the solid metal ring at a rate to cool it without entrapment of unburned fuel against the combustor walls; the combustor further including a transition mount including a solid metal support ring welded to the aft end of a porous laminated metal combustor wall, the mount including a seal ring retained by a keeper and a thin conical, axially extending beam portion that is flexible to serve to accommodate differential thermal expansion of the combustor relative to a grounded support component and wherein the solid metal support also includes a plurality of effusion cooling holes located immediately outboard of a weld bead between the solid metal support and the porous laminated combustor wall for cooling a downstream nozzle.
