Abstract
Abstract From the elongated platform of an air-cushion vehicle depend a plurality of cushion containing skirts alined behind each other in two parallel rows on opposite sides of the longitudinal axis, with each skirt of one row being paired with a corresponding skirt of the other row at a same longitudinal level along said rows. Two lift fans are fitted on the platform at a same longitudinal level and on both sides of the longitudinal axis. The discharge of each fan is fractionated and connected via a ramified ducting to the individual skirt contained cushions of the row on the same side as said fan.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
202 words
A surface effect machine having a platform of elongated shape with a major longitudinal axis and a minor transverse axis, said platform extending on both the portside and the starboardside of said longitudinal axis as well as on both the prowside and the sternside of said transverse axis, comprising: a port row formed of a multiplicity of continuous cushion seals confining as many individual mutually segregated cushion spaces is generally longitudinal alignment under said portside of said platform, a starboard row formed of a further multiplicity of continuous cushion seals confining as many individual mutually segregated cushion spaces in generally longitudinal alignment under said starboardside of said platform, respective individual cushion spaces of said port row and starboard row being paired in generally transverse alignment, a port ducted supply having a fractionated discharge, located at said platform portside, a starboard ducted supply having a fractionated discharge, located at said platform starboardside in generally transverse spacing with said port supply, a port ramified ducting connecting said fractionated discharge of said port supply to plural individual cushion spaces of said port row, and a starboard ramified ducting connecting said fractionated discharge of said starboard supply to plural individual cushion spaces of said starboard row.
Claim 2
Dependent Claim
202 words
A surface effect machine having a platform of elongated shape with a major longitudinal axis and a minor transverse axis, said platform extending on both the portside and the starboardside of said longitudinal axis as well as on both the prowside and the sternside of said transverse axis, comprising: a port row formed of a multiplicity of continuous cushion seals confining as many individual mutually segregated cushion spaces is generally longitudinal alignment under said portside of said platform, a starboard row formed of a further multiplicity of continuous cushion seals confining as many individual mutually segregated cushion spaces in generally longitudinal alignment under said starboardside of said platform, respective individual cushion spaces of said port row and starboard row being paired in generally transverse alignment, a port ducted supply having a fractionated discharge, located at said platform portside, a starboard ducted supply having a fractionated discharge, located at said platform starboardside in generally transverse spacing with said port supply, a port ramified ducting connecting said fractionated discharge of said port supply to plural individual cushion spaces of said port row, and a starboard ramified ducting connecting said fractionated discharge of said starboard supply to plural individual cushion spaces of said starboard row.
Claim 3
Dependent Claim
50 words
A machine as claimed in claim 1, further comprising a central motor unit fitted to said platform substantially on said longitudinal axis thereof, and two transmission means radiating from said central motor unit and extending respectively to said port supply and to said starboard supply to activate the same simultaneoUsly.
Claim 4
Dependent Claim
24 words
A machine as claimed in claim 2, wherein said two transmission systems extend substantially in a same transverse plane parallel to said transverse axis.
Claim 5
Dependent Claim
51 words
A machine as claimed in claim 1, wherein each of said port row and starboard row comprises individual cushion spaces both under said prowside and under said sternside of said platform, the overall distribution of said cushion spaces being generally symmetrical both about said longitudinal axis and about said transverse axis.
Claim 6
Dependent Claim
33 words
A machine as claimed in claim 4, wherein said overall cushion space distribution is such that a cushion space is wholly located in every one of the four quadrants defined by said axes.
