摘要： An amphibious vehicle achieves a stable ride, maneuverability, and high speed. The vehicle includes a hull having a “V” center portion with outboard sponsons. The sponsons reside between the front wheel wells and the rear wheels wells for improving lift and transition to planing. Shallow tunnels begin in rear portions of the front wheel wells and taper into the sponsons to release water trapped in the wheel wells. Inward facing turning edges also reside between the front and rear wheel wells and improve in-water handling. Wheels are retractable by pneumatic cylinders in parallel with air shock absorbers and suspension cutout in the hull allow the suspension to lower through the hull. Flaps reside under suspension members and rise to cover the suspension cutouts when the wheels are retractable when the wheels are raised to reduce drag. A Morse cable couple a rack and pinion unit to a jet drive.

摘要： An Amphibious Vehicle (AV) is capable of planing with less power than prior similar size amphibious vehicles and using mostly off-the-shelf part. Leading rear wheel well flaps are biased forward against the hull bottom for on-road use, and pivot back to fill a gap between the hull and retracted rear wheel, reducing drag during in-water use.

摘要： An Amphibious Vehicle (AV) is capable of planing with less power than prior similar size amphibious vehicles and using mostly off-the-shelf part. The AV uses an outdrive and propellor instead of a pump, and also include leading rear wheel well flaps which are spring biased forward against the hull bottom for on-road use, and pivot back to fill a gap between the hull and rear tire, reducing drag during in-water use. The combination of the propellor and wheel well flap allows planing with less horse power. An engine faces to the rear and either reversing differentials to reversing carrier and hubs provide correct wheel rotation. A reversing gear box attaches to an engine front and reverses rotation providing correct rotation for an outdrive and propellor.

摘要： An amphibious vehicle which on land looks remarkably like a conventional automobile. The wheels may be raised when the vehicle is in the water. The engine is placed in the stern, directly over the jet and transaxle, which provides room for four passengers. The vehicle has plates which slide under the wheels for use in water, and the plates do not extend up over the sides of the wheel wells.
摘要翻译：在陆地上看起来非常像传统汽车的水陆两用车。当车辆在水中时，车轮可能会升起。发动机放置在船尾，直接位于喷气式和变速驱动桥上，为四名乘客提供空间。车辆具有在车轮下方滑动以用于水的板，并且板不会在轮轴的两侧延伸。
