Benefits of technology
The present invention provides a silent, fast, efficient, and highly maneuverable military submarine jet propulsion system that overcomes the disadvantages of existing systems. The system uses plurality of shaftless rim propellers to accelerate water inside the system and generate the desired water jet flow thrust for each outlet, allowing the submarine to move forward, backward, up, down, right, and left easily, fast, efficiently, and silently. This system is highly effective and requires minimal dynamic losses, and it reduces the noise and acoustic signature of the submarine. Thus, the invention improves the overall performance of military submarines.
Problems solved by technology
These conventional submarine propulsion systems are known to be very noisy and inefficient due to the generated turbulences, the propeller cavitation effect and the generated vibrations that increase the acoustic signature of the military submarine resulting in an increase of its vulnerability to be detected by others Sonar systems.
Also, such conventional submarine propulsion systems are inefficient and slow with an excessive energy consumption because their propellers push water in all directions instead of being directed to the desired direction to give the highest thrust for the maximum efficiency, speed and maneuverability.

The present invention deals with a silent jet propulsion system installed inside the hull of a military submarine with a method for propelling a military submarine and the like to eliminate the conventional propulsion systems noise and to steer the military submarine in silent, fast, efficient and highly maneuverable fashion.In the present invention, there is no propeller installed outside the military submarine hull. The silent jet propulsion system of the present invention will generate a laminated turbulent free water jet flow thrust which will propel the military submarine in the desired speed and the desired direction.In the present invention, the desired speed and the desired direction of movement of the military submarine is accomplished by controlling the amount and the direction of the generated water jet flow thrust of the silent jet propulsion system installed inside the military submarine hull.
