A wind-water machine set is an evolving jet machine that moves the internal engine to the outside of the sleeve to work, instead of using a water jet as the main and air-jet as the auxiliary. When a ship uses multiple groups of wind-water machine set, there is a master control center for overall control and coordinated operation. Controlling the propulsion system makes the ship move forward and backward in an orderly manner. Control the surfing system to eliminate the bow water resistance and cooperate with the propulsion system. The steering control system is controlled to make the ship easy to operate the steering. Control the balance system to keep the ship balanced without swaying the roll angle. Control the draught system so that ships do not need ballast water. So that the ship can sail at super high speed, super fuel-efficient and safe.

An alternating Open Chamber Cavity for employing a very useful safe and controllable new lifting plus lubricating hydrodynamic force for effectively improving marine transportation in a seaway, I named SAFELY CONTROLLED, AUTOMATED WATER DISSECTED LUBRICATION AND LIFT FORCE, has been discovered and innovated for use by myself; and I have also invented the automated mechanism I named “FLEXIBLE POWER-FINS”, for controlling the safe exploitation of this beneficial natural phenomenon, as well as innovated a way to significantly improve the turning capabilities of a watercraft in motion.

In the absence of inventive practice, the hydrodynamic flows on both sides of a vertically oriented bluff body (e.g., cylinder) traveling through water tend to hug the bluff body proximate its curved back surface and to converge behind the bluff body, resulting in lateral sway of the bluff body. Exemplary inventive practice provides for attachment of a pair of waterjet-streaming devices at opposite axial ends of a bluff body such as a cylinder. The waterjet streams discharged by the two inventive devices, which adjoin the vertical bluff body, deflect the hydrodynamic flows on both curved side surfaces of the bluff body. The inventive apparatus thereby encourages a continued approximate parallelity of the hydrodynamic flows behind the bluff body, resulting in significantly greater stability of the bluff body. Some exemplary embodiments of the present invention provide for attachment of a single waterjet-streaming device at one axial end of the bluff body.

Systems and methods of reducing drag on outer surfaces of vehicles that are in contact with water using a polymer solution that reduces the drag on the outer surfaces of the vehicles as the vehicles travel through water. A polymer solution is passively ejected into the boundary layer of the water flowing past the outer surface of the vehicle. The polymer solution is mixed and introduced into the boundary layer passively with minimal or no usage of electrical energy. The passive mixing and ejection of the polymer solution minimizes energy consumption, thereby maximizing electrical energy consumption efficiency during operation of the vehicle.

A submersible vessel comprising: an elongated hull; at least one propeller mounted on a forward end of said hull and adapted to move said hull through water; said at least one propeller being of a size and configuration such that when it is rotated at an appropriate speed, it generates supercavitated water flowing from said at least one propeller and thence along an outer surface of said hull so as to diminish friction on the outer surface of said hull and facilitate high underwater speeds.
