Abstract:
1. An aircraft component being exposed to streaming surrounding air, comprising an inner wall; an outer wall, the outer wall having micro-perforations in a plurality of suction regions and a plurality of pressure regions, and the outer wall providing an external surface of the aircraft component and being displaced a distance from the inner wall, the distance defining a space between the inner wall and the outer wall; a plurality of partition walls being inserted within the space between the inner wall and the outer wall such that a plurality of sections form an alternating sequential physical arrangement of a plurality of pressure channels and a plurality of suction channels such that each of the plurality of pressure channels is adjacent to at least one of the plurality of suction channels, the plurality of sections extending from the inner wall to the outer wall, such that the plurality of suction channels are adapted and arranged for sucking surrounding air through the micro-perforations in the outer wall of the plurality of suction regions of the outer wall having a first combined surface area separated into at least two separate suction regions, and the plurality of pressure channels are adapted and arranged for feeding hot pressurized air through the micro-perforations in the outer wall to a plurality of pressure regions of the outer wall having a second combined surface area separated into at least two separate pressure regions; and the first combined surface area of the plurality of suction regions is significantly greater than the second combined surface area of the plurality of pressure regions, and the plurality of suction regions and the plurality of pressure regions are arranged in the same alternating sequential physical arrangement as the plurality of suction channels and the plurality of pressure channels; and a control device controllably coupling the plurality of pressure channels to a hot air reservoir and the plurality of suction channels to a vacuum reservoir.
