Abstract

A shield (32) is disposed in spaced relationship to the exterior surface of the combustor liner (18) of a gas turbine engine and extends over a plurality of very small holes (28) formed in the combustor liner so as to regulate flow of air to these holes. A portion of the air flowing along the exterior surface of the combustor liner is diverted for reverse flow in the path (44) provided between the shield and the combustor liner. Larger holes (52) are provided in the liner at the point of reversal of the air so that dirt particles in the air, because of the centrifugal force acting thereon, tend to flow through them. A second group of larger holes (56) coiled any remaining dirt particles during a second reversal of air flow. The very small holes are thus protected against being plugged by the particles. <IMAGE>
