Abstract
A propeller driven vehicle, such as an air cushion hovercraft, comprising a hull, a teardrop shaped cabin mounted on the hull and a propeller arranged in front of the cabin. A gutter shaped obstructing plate is pivotally mounted to each side wall of the cabin and is movable between a horizontal and vertical position. When the obstructing plate is moved from its horizontal position to obstruct the air flow from the propeller around the side wall of the cabin, a pressure differential is created on the cabin which is effective in steering the vehicle.
Claims6
An air cushion vehicle comprising
- a. a hull;
- b. means for supporting said hull on an air cushion;
- c. a cabin having vertical side walls mounted on said hull, said side walls being curved in a longitudinal direction to form a teardrop shape for said cabin;
- d. a propeller arranged in front of said cabin, said side walls guiding the flow of air from said propeller rearwardly;
- and
- e. at least one obstructing plate pivotally mounted on each said side wall for movement between a horizontal and vertical position, each said plate when moved from said horizontal position capable of disturbing the flow of air around the respective side wall to cause a pressure differential on said cabin to assist in steering the vehicle.
