Abstract
Abstract The invention has to do with a system designed to support and/or guide a ground effect machine (1) along a supporting surface (2). This system consists of structure (4) carrying a load (F), a floating partition (5) holding the cushion (9) and a flexible partition (10) defining laterally between the structure (4) and the partition (5) an enclosure of suspension (13) having a variable volume which is connected with the cushion (9) through calibrated orifices (6). The enclosure of suspension (13) has a convergent-divergent configuration, for example biconic. The area of the base (S), the area (S o ) at the level of the collar (15) and the angle (θ) of the enclosure (13) are predetermined and remain constant.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
248 words
A system for supporting and/or guiding a ground effect machine along a supporting surface, which includes: a solid structure incorporating the platform of said machine; a suspension enclosure situated under said solid structure; and a fluid cushion situated under said suspension enclosure and over said supporting surface, whereby said solid structure is approximately parallel to and spaced from said surface; said suspension enclosure being defined by said solid structure, a leak-proof partition and an apertured partition, said leak-proof partition attached at its top periphery to said solid structure and its bottom periphery to said apertured partition and being flexible and capable of folding up on itself, said apertured partition having at least one orifice of calibrated size, said leak-proof partition having a convergent-divergent configuration of two opposed truncated cones with their common smaller base located between said structure and said apertured partition, and including a reinforcement collar located between said solid structure and apertured partition and at said common smaller base of said truncated cones, said configuration being shaped and dimensioned in such manner that said apertured partition floats approximately parallel to said structure; said fluid cushion being bound by said apertured partition, side partitions attached at their tops to said apertured partition and separate and distinct from said leak-proof partition and by said supporting surface, and means for supplying with fluid under pressure the suspension enclosure and also said cushion, the latter being supplied through said enclosure and said at least one orifice of said apertured partition.
Claim 2
Independent Claim

Claim 3
Dependent Claim
19 words
A system as claimed in claim 1, wherein said reinforcement collar encircles the common base of the truncated cones.
Claim 4
Dependent Claim
25 words
A system as claimed in claim 1, wherein said reinforcement collar is made of a flexible band, encircling the common base of the truncated cones.
Claim 5
Dependent Claim
