## CPC

- B60V 1/08: wherein the cushion is created during forward movement of the vehicle by ram effect
- B60V 1/04: wherein the cushion is contained at least in part by walls
- B60V: AIR-CUSHION VEHICLES

## Abstract

A ground effect vehicle apparatus comprising a vehicle body of integral and contiguous construction including a medial portion having an aerodynamic upper surface, and a pair of spaced apart laterally positioned portions separated by the medial portion. Lower extremities of the laterally positioned portions extend downwardly below the medial portion to restrain air flow between them as it moves toward the rear of the body. Forward extremities of the laterally positioned portions extend forward of the medial portion to, again, restrain air flow from moving laterally. Power plants are mounted within the medial portion and support aircraft type propellers positioned forward of the medial portion of the body. The propellers are mechanized for moving over an arcuate vertical range, such that their force vectors are directable between the horizontal and approximately 45 degrees above the horizontal. In this manner, the propeller forces ram air below and to the rear of the medial portion of the vehicle body thereby developing cushion effect lift and forward thrust.

## Claims

### Claim 1

A ground effect vehicle apparatus comprising: a vehicle body of integral and contiguous construction including a medial portion having an aerodynamic upper surface, and a pair of spaced apart laterally positioned portions separated by the medial portion; lower extremities of the laterally positioned portions extending downwardly below the medial portion; forward extremities of the laterally positioned portions extending forward of the medial portion; a pair of fuel tanks mounted to the medial portion and extending forwardly therefrom; a pair of power plants positioned forwardly of the fuel tanks, each of the power plants engaging a propeller thereof functionally enabled for moving over an arcuate range such that a force vector developed by the propeller is movable between horizontal and approximately 45 degrees above the horizontal, for forcing ram air below and to the rear of the medial portion of the vehicle body thereby developing cushion effect lift.

### Claim 2 (depends on 1)

The apparatus of claim 1 further providing means for lateral rotation of the propellers enabling left and right steering vectors.

### Claim 3 (depends on 1)

The apparatus of claim 1 further comprising a cockpit enabled for control of the apparatus.

### Claim 4 (depends on 1)

The apparatus of claim 1 wherein the lower extremities of the laterally positioned portions are adapted for supporting the apparatus for moving in contact with a hard smooth surface.

### Claim 5 (depends on 1)

The apparatus of claim 1 wherein the lower extremities of the laterally positioned portions are adapted for supporting the apparatus for moving in contact with a snow covered surface.
