ABSTRACT:
An air cushion vehicle has a substantially-endless downward and inward directed rigid primary nozzle supplied with air under pressure for producing an air curtain that creates and confines a central primary air cushion beneath the vehicle which mainly supports it. The vehicle also has at least two substantially-endless downward and inward directed rigid secondary nozzles arranged on generally opposite sides of the primary nozzle and each supplied with air under pressure for producing an air curtain that creates and confines a stabilizing air cushion beneath the vehicle smaller than the primary air cushion. The two stabilizing cushions are preferably of the same size and shape and each smaller than the primary cushion. When the vehicle leans or dips toward one of the stabilizing cushions when travelling over a surface, e.g. land or water, the pressure of that one stabilizing cushion increases and tends to push the vehicle back up to a level position.
