ABSTRACT:
A vehicle travelling on air cushions comprises a lifted structure and a lift arrangement which comprises at least one multilobular skirt having a plurality of first lobes open towards the inside of the vehicle. A lower part of each first lobe converges in a downwards direction with respect to the structure. At least in the vicinity of the rear of the vehicle, each open first lobe has within it an anti-damage lobe which diverges in a downwards direction with respect to the structure at an inclination such that the values of the angles formed between the respective outermost generatrices of the first and anti-damage lobes with respect to the vertical are substantially equal. The side edges of the anti-damage lobe are each connected along a rectilinear connection to the opposite side walls of the first lobe which converge in a downwards direction with respect to the structure. The anti-damage lobe is also at its lower part, and in a horizontal plane, connected to the base of the first lobe. Since the slope of the anti-damage lobe is of opposite inclination to that of the first lobe, the lower part of the anti-damage lobe trails rather than leads when at the vehicle's rear. So the anti-damage lobe slips more easily over projections from rough terrain and lifts the skirt. An access or gap admits pressurized air into the volume between the first and anti-damage lobes. From this volume lower openings may lead to discharge water from the volume.
