Abstract
A surface effect vehicle having a pair of lifting scoops, or air foils, mounted on a vehicle body, one in front and the other in the rear. Each lifting scoop has an arched leading edge to collect air under the scoop to lift the vehicle on a cushion of air. The vehicle having a pusher-type engine with a propeller to push the vehicle. There are louvers in the lifting scoops to regulate the height the vehicle travels on a cushion of air, and non-trip appendages on the tips of the lifting scoops to aid the scoops in lifting the vehicle from a surface.
Claims2
A surface effect vehicle for use on water and other surfaces, comprising:
- a vehicle having a body with a nose section, a cockpit and an aft section;
- a pair of lifting scoop means mounted on said body, where said lifting scoop means includes a first scoop means mounted on said nose section and a second scoop means mounted on said aft section, said first scoop means having one-half the area of said second scoop means to provide initial lift of said nose section;
- said first scoop means and said second scoop means each having a delta shape with an apex facing said aft section, and an arched leading edge at the broadest width of said delta shape facing said nose section;
- a pusher type engine with a propeller mounted on said body to move said surface effect vehicle, and a rudder mounted behind said engine to turn said vehicle, where said pair of lifting scoop means collect air under said delta shape to lift and support said vehicle over a surface to allow said vehicle to move on a cushion of air;
- said first scoop means and said second scoop means having a height and width at said leading edge in a ratio of about 1:7, where 1 represents the height;
- said first scoop means and said second scoop means each having a length extending along said body, starting at said leading edge, and said width at said leading edge in a ratio of about 3:7, where 3 represents the length;
- said first scoop means is separated from said second scoop means by a ratio of about 4:7 where 4 is measured from said leading edge of said first scoop means to said leading edge of said second scoop means, and 7 is the width of said leading edge of said second scoop means;
- said first scoop means and said second scoop means each having an angle of attack of about 16 degrees from the horizontal measured from the rear of said scoop means to said arched leading edge to provide lift-off for said vehicle;
- said first scoop means having a movable louver means to open and close to regulate the height said vehicle travels over a surface;
- said second scoop means having at least one pair of louver means to open and close to regulate the height said vehicle travels over a surface;
- said first scoop means and said second scoop means having tips, and non-trip appendage means extending from said tips at an upward angle to the horizontal to provide lift-off to part said vehicle from a surface;
- said appendage means having an upward angle to the horizontal of about 30 degrees;
- said body is supported on said first scoop means and said second scoop means above a surface when said scoop means are in contact with the surface.
