Dynamically balanced, fluid submersible and movable object

Abstract

A dynamically balanced, fluid submersible, self propelled object that may be suitable as a toy or for transporting man and material. The object, through a combination of negative and positive buoyancy, and control surfaces, can descend and ascend repeatedly. The submersible object includes a tail fin assembly of essentially four fins radially extending from the object body, and a pair of wings, where the position and size of the fins and wings are controlled and balanced by specific perimeters to ensure the self propulsion.

1 . A dynamically balanced, self propelled, submersible object for use in an variety of fluids of differing specific gravity, the submersible object comprising; 
 a.) an elongated body of predetermined length having a broadened center portion tapering fore and aft to tapered ends;    b.) a pair of laterally extending wings projecting from said center portion; and,    c.) four radially extending tail fins at the aft tapered end, where said tail fins are about 90° apart, with an opposing pair aligned with said wings, and where said opposing tail fins are angled about 7° downwardly to ensure that said wings and said opposing tail fins do not stall at the same speed.    
     
     
         2 . The submersible object according to  claim 1 , wherein said opposing tail fins extend axially beyond said aft tapered end.  
     
     
         3 . The submersible object according to  claim 2 , wherein the surface area of a said wing is about six times that of a said tail fin.  
     
     
         4 . The submersible object according to  claim 3 , wherein the distance between the surface area centers of said wing and said tail fin is about 62.5% of said predetermined length.  
     
     
         5 . The submersible object according to  claim 4 , wherein the dynamic centers of said wings and opposing tail fins are forward of said surface area centers.  
     
     
         6 . The submersible object according to  claim 5 , wherein the center of buoyancy for said object is forward of the dynamic centers of said wings.
