  • Patent number: 4747459
    Abstract: A hovercraft includes a rigid body and a flexible skirt pending from a lower periphery thereof. A main engine and propeller are coupled to the rigid body and provide a main propeller thrust. A plurality of thrust control vanes are located downstream of the propeller and divide the main propeller thrust into a horizontal thrust component directed rearwardly of the thrust control vanes and a vertical thrust component directed to a location under the rigid body so as to cooperate with the flexible skirt to form an air cushion on which the hovercraft rides. A plurality of steering control vanes are located downstream of the thrust control vanes and control the forward direction of the hovercraft. A single control stick controls the operation of both the thrust control vanes and the steering control vanes.
