  • Air cushion vehicle having volute side thrusters
    Patent number: 5307893
    Abstract: An air cushion vehicle having improved maneuverability is produced by providing air discharge vents for diverting at least a portion of the pressurizing cushion air from the side of the volute housing opposite that to which the vehicle is being turned, and discharging it from a thruster at said opposite side in a direction away from the direction of the turn. The thruster is located at a forward position, above the deck of the vehicle and adjacent the centerline thereof, and the discharged air produces a thrust which causes the vehicle to roll in the direction of the turn and permits cushion air to escape from beneath the vehicle at said opposite side, producing a thrust complimentary to the thrust from the volute housing.
