ABSTRACT:
This invention relates to ground-reaction machines, such as hovercraft, and is particularly concerned with flexible enclosure arrangements, often referred to as skirts, for enclosing a fluid cushion beneath the loading platform of the machine. According to the invention, air fed into the arrangement to form the cushion, is channelled or directed by cells having walls which are linked in series along the periphery of the platform. This ensures the feed and enclosure of a single undivided central cushion at a pressure which is substantially uniform and of which the boundaries represent an auxiliary structure. In a preferred construction, each of the cells is bounded by two flexible walls, all the horizontal sections of which are of bi-convex, lenticular shape.
