Abstract
A small sized air cushion vehicle includes a hull having a planar bottom surface with an upstanding lower flange disposed and extending upwardly at an angle of between 24.degree. and 30.degree. with respect to the planar bottom surface of the hull. A hollow plenum extends through the periphery of the hull. Apertures are formed in the upstanding lower flange of the hull and disposed in fluid flow communication with corresponding apertures in a plurality of inflatable members which are attached to the flange of the hull. Each inflatable member includes a downwardly extending aperture which directs air flow from the hollow plenum in the hull through each of the inflatable members to lift the vehicle a short distance above an underlying surface as well as providing forward or sideways propulsion. A steering mechanism is mounted rearward of the fluid propulsion source to control the direction of movement the vehicle. The occupant seating area includes a seat longitudinally movable and lockable within the vehicle for occupant comfort as well as for forward positioning during lift-off to control weight distribution in the hovercraft.
