Abstract: A flexible gas cushion confinement cell for a ground effect vehicle comprising two flexible walls extending substantially parallel to one another with flexible partitions extending transversely of the walls and joining them together over at least a part of their height. The walls define, in conjunction with one another and with the partitions, juxtaposed compartments which are open at their upper ends to enable them to be connected to a gas pressure source and which are closed or substantially closed at their lower ends. The cell is approximately of horseshoe-shape and can be provided with an additional wall and transverse deflectors extending between the legs of the horseshoe-shaped cell.
