Abstract
An apparatus for producing vertical lift in a vehicle. In one embodiment, two sets of trans-flow fans discharge air through multi-directional vane assemblies that direct the discharged air outward and downward. Each one of the sets of fans is positioned on opposite sides of the vehicle. The multi-directional vane assemblies include vertical vanes that direct the discharged air fore and aft and horizontal vanes that direct the discharged air downward at various angles. In one embodiment, the vehicle includes a hovercraft skirt and a portion of the discharge air is directed into the skirt, causing the vehicle lift vertically on a cushion of air. In one such embodiment, a flow director controls the amount of discharged air flowing through the inlet to the volume defined by the skirt.
Claims19
An apparatus for producing vertical lift in a vehicle, said apparatus comprising:
- a first fan positioned on a first side of the vehicle, said first fan being a trans-flow fan, said first fan having an axis of rotation substantially parallel to a longitudinal axis of said vehicle;
- a second fan positioned on a second side of the vehicle, said second fan being a trans-flow fan, said second side opposite said first side, said second fan having a direction of rotation opposite that of said first fan, said second fan having an axis of rotation substantially parallel to said longitudinal axis of said vehicle;
- a first vane assembly positioned adjacent a discharge outlet of said first fan, said first vane assembly having a first discharge position configured to direct air from said first fan in a forward direction, said first vane assembly having a second discharge position configured to direct air from said first fan in a rearward direction;
- a second vane assembly positioned adjacent a discharge outlet of said second fan, said second vane assembly having a first discharge position configured to direct air from said second fan in a forward direction, said second vane assembly having a second discharge position configured to direct air from said second fan in a rearward direction;
- and
- a skirt defining a volume, said skirt configured to be in communication with said discharge outlet of at least one of said first fan or said second fan, said skirt configured to create a cushion of air that supports said frame.
An apparatus for producing vertical lift in a vehicle, said apparatus comprising:
- a first fan positioned on a first side of a frame of the vehicle, said first fan being a trans-flow fan, said first fan having an axis of rotation substantially parallel to a first axis of said fuselage, said first trans-flow fan having a first fan exhaust outlet configured to exhaust a flow of air from said first fan;
- a second fan positioned on a second side of said frame, said second fan being a trans-flow fan, said second side opposite said first side, said second fan having a direction of rotation opposite that of said first fan, said second fan having an axis of rotation substantially parallel to said first axis of said frame;
- a first vane assembly including a plurality of vanes, said first vane assembly adjacent said first fan exhaust outlet, said plurality of vanes selectively directing a portion of a flow of exhaust air from said first fan exhaust outlet;
- a second vane assembly including a plurality of vanes, said second vane assembly adjacent said second fan exhaust outlet, said plurality of vanes selectively directing a portion of a flow of exhaust air from said second fan exhaust outlet;
- and
- a skirt enclosing a volume, said skirt configured to be in communication with at least one of said first fan exhaust outlet and said second fan exhaust outlet, and said skirt configured to create a cushion of air that supports said frame when said volume receives a flow of air from said at least one of said first fan exhaust outlet and said second fan exhaust outlet.
An apparatus for producing vertical lift in a vehicle, said apparatus comprising:
- a frame having a first axis;
- and
- a pair of fans attached to said frame, said pair of fans each having an axis of rotation substantially parallel to said first axis of said frame, said axis of rotation of a first one of said pair of fans being opposite said axis of rotation of a second one of said pair of fans, each one of said pair of fans having a squirrel cage rotor and an outlet, a first one of said outlets positioned to discharge on one side of said first axis of said frame and a second one of said outlets positioned to discharge on an other side of said first axis, said outlets configured to direct air from said pair of fans to provide lift to said frame, said outlets configured to direct air laterally to provide lateral motive force to said frame.
