Abstract
Known porous laminates of the kind wherein ambient atmosphere each side of the laminate is connected via holes and passageways, the latter lying within the laminate thickness in planes parallel with the faying faces, suffer from airflow energy loss which arises from the changes in direction undergone by the airflow while in transit from one side of the laminate to the other side thereof. The invention provides extra holes on the high pressure side of the laminate, over those points in the passages wherein the greatest change in direction of flow occurs, so as to re-energize the airflow which has reached those points via the relevant holes of the known arrangement.
