Abstract
An air-cushion vehicle is provided with an inflatable flexible skirt of bag-like form. The bottom of the skirt defines a convex face in close proximity to the surface over which the vehicle travels so as to form an atmosphere-seeking plenum gap. The flexible skirt is impermeable except for the convex face which is perforated so as to allow skirt inflation air to bleed through the face and suppress any vibration induced by the Bernoulli effect.
