摘要:
A ground-effect machine is designed for travelling along a bearing surface through the medium of a lift cushion system provided with a suspension system which includes a deformable pneumatic chamber interposed between the machine frame and the cushion proper. This cushion and this chamber have an associated fluid circuit which may comprise a passage intercommunicating them and which is so designed that the cushion pressure or lift pressure is, depending on the type of ground-effect machine, either greater or smaller than ambient pressure but in any event closer thereto than the pneumatic chamber pressure or suspension pressure. This attitude of this ground-effect machine is compensated through regulation of these lift and suspension pressures in order to maintain their ratio at a predetermined value, by detecting any deviation of their actual ratio from said predetermined value, and by restoring it thereto with a relatively long response time through variation - modulated as a function of the detected deviation - of a pressure loss provided at a convenient location of the above-mentioned fluid circuit, preferably at the intercommunicating passage.

The invention comprehends ground effect guiding means for a machine moving along a track having at least one guiding surface having a vertical component, the machine having a structure having one surface near the guiding surface, the guiding means comprising means for bounding fluid cushion enclosures between the machine structure and the guiding surface, said structure bearing on said surface by way of said enclosures, the enclosures together forming at least one group in turn consisting of at least two fluid cushion enclosures disposed in consecutive relationship lengthwise of the machine; means for bounding a respective deformable chamber between the machine structure surface and the or each group of fluid cushion enclosures, and means for securing all the fluid cushion enclosures of the or each group to their respective chamber; means for supplying fluid to the fluid cushion enclosures; and means for supplying fluid to the or each deformable chamber.

The space between two bodies moving relatively to each other is partitioned in order to form a plurality of overpressured or underpressured fluid cushions. The partitioning is provided by a waffled flexible sheet fixed to one of the two bodies whereby to confine, jointly with the other body, the space therebetween, while at the same time subdividing the same into a plurality of contiguous cells separated from one another by the upstanding waffles on said waffled sheet. The cells are nested into one another, with central cells surrounded by peripheral cells.
