ABSTRACT:
An aero marine vehicle having a fuselage having front wings extending from its respective left and right sides. Engines are mounted in these wings and their drive propellers are supported adjacent the rear edge of these wings. A pair of laterally spaced hull members are supported beneath the respective right and left wings. A plenum chamber is formed in each of the hull members with the bottom wall of the hull members forming the bottom wall of the plenum chambers. Exhaust lines are connected between the engines and the respective plenum chambers. The bottom wall of the hull members has a plurality of exhaust ports formed therein which allow the escaping exhaust gases to form a boundary layer of air between the bottom wall of the hull members and the water they are floating upon to overcome the suck-down effect of the water upon the hull member. The majority portion of the interior of the hull members form a buoyancy chamber. The rear struts extending downwardly from the front wings of the vehicle have their bottom ends pivotally attached to a bracket mounted atop the respective hulls. The front strut members extending downwardly from the wings have their bottom end pivotally attached to top end of a rod extending from a hydraulic cylinder mounted within the hull members. This structure allows the front end of the hull members to be pivoted upwardly and downwardly a predetermined number of degrees with respect to the horizontal axis of the hull members.
