Abstract
A combustion liner for a gas turbine engine operating at high temperatures has portions of the combustion liner double-walled, with a narrow clearance between the inner and outer walls through which cooling air flows to cool the liner. The surfaces of the walls which define these cooling air inlets are roughened to increase heat transfer from the air to the wall. The walls are joined and held apart by spacing strips extending axially of the liner and bonded to the overlapping wall sections. Large combustion air inlet holes extend through the overlapping wall sections at some points. Auxiliary air inlets for liner cooling are provided downstream of these combustion air inlet holes.
