Speedboat or high speed watercraft with dynamic hull

摘要

The vehicle can be referred as a type of speedboat, because it is designed for very high speed on water. Preferably, the vehicle consists of a hollow shell 1 of circular section that floats and spins on the surface S of the water. The engine 2, which also includes the cabin, is located inside the shell 1. The output shaft of the engine 2 drives the shell 1 about axis O. As the shell 1 spins, the viscous forces between the spinning surface of the shell and the liquid, cause movement of the vehicle. Means of preventing counter rotation, of the engine 2 inside the shell about axis O are included. This is provided by the weight of the engine, which hangs low and off-centered about axis O; and by the aerodynamic uplift acting on the tail 3, through the lever arm action on the frame of the engine 2.
