Propulsion system

Abstract

A propulsion system for a jet- or rocket-propelled vehicle in which the resulting jet exhaust nozzle profile is a 3D spiral. The propulsion system can be applied to any jet- or rocket-propelled vehicle, including aircraft and watercraft. The propulsion system also contemplates a vehicle including the modified 3D spiral nozzle exhaust profile

1 . A propulsion system, comprising:
 a vehicle producing exhaust;   a conduit connected to said vehicle, the exhaust flowing through said conduit; and   an exhaust altering attachment disposed on said conduit, the attachment having a slit defined therein dimensioned and configured for expelling the exhaust from said conduit in a three dimensional helical pattern.   
   
   
       2 . The propulsion system according to  claim 1 , wherein said slit comprises an opening defined by a pair of interconnectable side portions. 
   
   
       3 . The propulsion system according to  claim 1 , wherein the side portions of said slit are contoured to ensure the exhaust is expelled in a three dimensional helical pattern. 
   
   
       4 . The propulsion system according to  claim 1 , wherein said slit comprises a generally S-shaped opening. 
   
   
       5 . The propulsion system according to  claim 1 , wherein said slit comprises a first S-shaped portion and a second S-shaped portion perpendicularly disposed across said first S-shaped portion. 
   
   
       6 . The propulsion system according to  claim 1 , wherein said conduit is selected from the group consisting of jet exhausts, rocket exhausts and self-propelled vehicle exhausts. 
   
   
       7 . The propulsion system according to  claim 1 , wherein said conduit is a large sphere and said exhaust altering attachment is a rotatable smaller sphere disposed inside the larger sphere, whereby the slit is rotatably controlled by the rotation of said smaller sphere so that the direction of flow of the exhaust is controlled by the movement of said smaller sphere. 
   
   
       8 . The propulsion system according to  claim 1 , wherein said exhaust altering attachment comprises an extended portion that performs as a rudder.
