Military submarine silent jet propulsion system

Abstract

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.

We claim: 
     
         1 - A silent jet propulsion system is installed inside the hull of a military submarine and a method is presented 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. 
     
     
         2 - The silent jet propulsion system of  claim 1  has no propeller installed outside the military submarine hull. 
     
     
         3 - The silent jet propulsion system of  claim 1  comprises plurality of jet propulsion units. 
     
     
         4 - Each one of the jet propulsion units of  claim 3  comprises one jet propulsion unit shell and one jet propulsion engine unit. 
     
     
         5 - Each one of the jet propulsion engines' units of  claim 4  comprises plurality of shaftless rim propellers and plurality of lamination cylinders that are responsible for generating a laminated turbulent free water jet flow thrust which will drive the military submarine in the desired direction. 
     
     
         6 - The speed of the military submarine will be determined by controlling the resultant vectored water jet flow thrust which is generated by all units of the silent jet propulsion system of  claim 1 . 
     
     
         7 - Forward, backward, up, down, right and left direction of the movement of the military submarine is accomplished by controlling the amount and the direction of the generated water jet flow thrust of each one of the jet propulsion engines' units of  claim 3 . The resultant vectored generated total water jet flow thrust of the silent jet propulsion system of  claim 1  will decide the resultant vectored speed and direction of movement of the military submarine. 
     
     
         8 - For the silent jet propulsion system of  claim 1 , the number of the jet propulsion units, the number of the lamination cylinders, the number of the shaftless rim propellers and the number of fins of the shaftless rim propellers can be changed, increased or decreased according to the size and weight of the military submarine to be installed in to obtain the best desired performance of being silent, fast, efficient and highly maneuverable military submarine.
