A low cost viscous resistance reducing cladding for a hull includes an air bag having an outer face for draining water. Each airbag includes an inflation chamber that includes a substantially open space that does not impede air flow therethrough. The bladder is inflated by charge air to a pressure higher than the adjacent hydrostatic pressure. The airbag material includes a reinforcing fabric for withstanding forces encountered during operation and sealed by a sealant so as to render substantially air impermeable. The outer drainage surface of each airbag is connected with the inflation chamber through a restrictor hole. Air flows from the plenum through the restrictor aperture into the drainage layer.
本申请公开了一种用于船体的低成本粘滞阻力减小包层,其包括气囊,该气囊的外部面用于排水。各气囊包括充气室,该充气室包括基本开口空间,该基本开口空间并不阻碍空气流过它。气囊通过增压空气而膨胀至高于相邻流体静压力的压力。气囊材料包括增强织物,该增强织物用于承受在操作过程中遇到的力,并由密封剂密封,以便使得基本不透空气。各气囊的外部排水表面通过限制器孔而与充气室连接。空气从充气室流过限制器孔进入排水层。
