Abstract: 1,087,734. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. June 18, 1964 [June 21, 1963], No. 24820/63. Heading B7K. A gas cushion vehicle wherein the cushion is contained for at least part of its periphery by a wall movably attached to the vehicle body and wherein, in operation of the vehicle, fluid streams between the wall and the surface over which the vehicle operates, is provided with means responsive to variations in the flow characteristics of the fluid stream, which variations result from a variation in a clearance between the bottom of said wall and said surface, for moving the wall away from and towards said surface in response to such variation in flow characteristics, whereby said wall is moved away from said surface when the clearance is reduced and towards said surface when the clearance is increased. The wall containing the cushion comprises a plurality of contiguous members 5, which may be rigid or flexible, pivotally attached at 9 to the main body of the vehicle to form a clearance 11 with the ground surface 3, the clearance being controlled by actuation of a control rod 13 which causes the member 5 to rock about pivot 9. A probe 12 extends through the member 5 to sense the flow characteristics through clearance 11 from cushion space 10 to control actuation of rod 13 in response to variations in the flow characteristics. In another arrangement air issues from an adjustable hollow wall or duct to issue from the bottom of the duct as a fluid curtain, the interior of the wall or duct having a pressure head which senses the variations in pressure resulting from variations in ground clearance at the curtain to cause adjustment of the inclination of the wall. In another arrangement gas is streamed down the outer surface of a single wall to form a curtain, sensing devices, which may be a vane in the air-flow, being provided to control movement of the wall. In other arrangements the wall is hollow and flexible and is constructed in association with a sealed chamber to deflect automatically in response to pressure variations in a flow of curtain-forming gas through the wall. Control apparatus for moving the wall is described and pressure heads may be formed in the base of the vehicle to detect deviation in pitch and roll to actuate a wall part aft of the detecting point to correct the deviation. Reference has been directed by the Comptroller to Specification 935,825.
