Title: Ammunition with electromotor

Description:
FIELD OF INVENTION 
     This invention is directed to ammunition, and in particular, to ammunition having a rotating stabilizing element. 
     BACKGROUND 
     Ammunition, such as, for example, shotgun ammunition, includes a shell body, submunition, propellant, and primer. Conventionally, rifled barrels and/or fin stabilizers are used to stabilize munitions in flight. However, such conventional stabilizing methods have proven to be insufficient in achieving long-range accuracy. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to increase accuracy and flying range of a submunition. 
     Ammunition according to an exemplary embodiment of the present invention includes a projectile, and an electromotor disposed within the projectile. The electromotor includes a rotor having an axis of rotation aligned with a flight path of the projectile. 
     In an exemplary embodiment, the ammunition further includes a propellant, and a primer that ignites the propellant. 
     In an exemplary embodiment, the ammunition is handgun, shotgun, rifle, mortar or rocket ammunition. 
     A projectile weapon according to an exemplary embodiment of the present invention includes an electrical power source for delivering electrical power to an electromotor of a projectile delivered from the projectile weapon, the electromotor including a rotor having an axis of rotation aligned with a flight path of the projectile. 
     In an exemplary embodiment, the electrical power source is a battery. 
     In an exemplary embodiment, the projectile weapon includes a stock, and the power source is disposed within the stock.

     DETAILED DESCRIPTION 
       FIG. 1  shows a shotgun ammunition, generally designated by reference number  1 , according to an exemplary embodiment of the present invention. The shotgun ammunition  1  includes a shell body  6 , submunition  2 , propellant  8  and primer  7 . The propellant  8  may be, for example, gunpowder or a nitro-cellulose based powder. An electromotor  10  is disposed within the shell body  6 . The electromotor  10  is positioned so that the axis of rotation of its rotor is aligned with the ammunition flight path. An external power source  3  is used to activate the electromotor  10 . The external power source  3  may be, for example, a battery and may be electrically connected with electrical connections  5  of the electromotor  10  by wires  4 . Current flows through the wires  4  from the external power source  3  to the electrical connections  5 . 
     Operation of the ammunition  1  according to an exemplary embodiment of the present invention is as follows: 
     After the ammunition  1  is fixed in the gun tube and the bolt of gun is shut, the conduction loop is made and immediately current flows from the external power source  3  through the wires  4  to the electrical connections  5 . The delivered current activates the electromotor  1 , which starts to rotate at, for example, 5,000-17,000 rpm. After the gun is fired, the ammunition  1  flies with the functioning electromotor  1  inside the shell body  6 . The rotation of the electromotor  6  stabilizes the ammunition&#39;s flight path due to the effect of gyroscopic forces produced by the rotating rotor. 
       FIG. 2  is rocket ammunition, generally designated as reference number  20 , according to an exemplary embodiment of the present invention. When rocket ammunition  20  is loaded, the electromotor  21  is activated with the use of the power source  23 , which is connected to electromotor  21  with wires  24  and  25 . 
       FIG. 3  shows a small arms weapon, generally designated by reference number  35 , and associated ammunition, generally designated by reference number  30 , according to an exemplary embodiment of the present invention. The small arms weapon may be, for example, a rifle. The ammunition  30  includes a bullet  31 , and projectile  32  with an electromotor that receives electrical energy through wires  33  and  34 . 
     As shown in  FIG. 4 , an electrical battery  36  is disposed inside the butt  37  of the small arms weapon  35 . In other exemplary embodiments, the battery  36  may be positioned within other parts of the rifle  35 , such as in other parts of the rifle stock, or external to the weapon  35 . 
       FIG. 5  shows a mortar-gun, generally designated by reference number  41 , and associated bomb, generally designated by reference number  42 , according to an exemplary embodiment of the present invention. When the bomb  42  is positioned within the barrel of the mortar-gun  41 , current is delivered from the power source  44  to electromotor  43  through wires  45  and  46 . 
     While particular embodiments of the invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications may be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
