REVERSIBLE PROPULSION SYSTEM

摘要

The "Reversible Propulsion System" is a system that, taking advantage of som principles of the mechanics of fluids, allows to give to the body to which the system i applied a directional mechanical thrust with a good mechanical efficiency, using variously alternated or random motion of the fluid in which the body in submerged. It is manufactured with a series of valves, passive or active that offer an extremely different resistance according to the direction and the way of the relative motion between the body to which they are applied and the liquid in which the body is submerged. The system can be also applied as small motor using the functional feature of the "shape memory alloys or polymers" or of some nano-material or biotechnological material producing a directional mechanical trust, using electrical signal coming from externa driving source.
