Abstract
An exhaust liner assembly for a gas turbine engine contains a unitary liner sheet and an impingement sheet, which contain holes for cooling air to enter chambers that are defined by chemically milled areas in the liner. The chambers are in an isogrid pattern, with the chambers having a polygon shape defined by walls that are left after the liner is milled. The walls intersect at nodes and fasteners are attached to the nodes to attach the impingement sheet to the liner.
