  • Patent number: 10139207
    Abstract: A streamlined projectile is disclosed that includes a base or rear having a plurality of concentric sections located within each other at the aft of the projectile and in successively smaller sizes. Within each concentric section is a chamber having a wall perpendicular to expanding combustion gasses, with the total area of these walls being greater than an area of the rear of the projectile itself. This creates a larger projectile base for a propellant to push against and for that explosion to be held within the section chamber for a longer period than that of a standard boattail or flat-tail projectile. In addition, the concentric sections at least partially negate atmospheric drag by occupying the region behind the projectile where a partial vacuum forms, resulting in a projectile that will go faster and further for a given propellant charge.

  • Patent number: 8794156
    Abstract: A projectile package loaded in a firearm includes a projectile having a rod attached to its rear region. The rod is attached to a drag member or vanes having elastic properties. When fired, the projectile is expelled from the barrel of the firearm. Upon exiting the barrel and until the projectile reaches its effective range, reactionary air forces caused by the projectile traveling through the air result in the elastic vanes orienting themselves in a tight formation behind the rear region of the projectile. As a result, the vanes do not detrimentally affect the aerodynamics of the projectile's flight within the effective range of the projectile. However, once the effective range of the projectile has been exceeded, the slower velocity of the projectile causes the elastic vanes to laterally fan or spread out so as to impede the forward progress of the projectile.

  • Patent number: 8640623
    Abstract: A multiple-purpose projectile assembly includes an anti-personnel projectile, an armor-penetrating projectile, a propellant, a base bleed gas, and a primer. The anti-personnel projectile includes a cavity having a scored surface and is made out of a soft metal. The armor-penetrating projectile is made from a hard metal and is housed partially within the cavity of the anti-personnel projectile prior to firing from a weapon. The propellant and the primer are both housed within the cavity. The firing of the projectile assembly causes the armor-penetrating projectile to drive into the primer, thereby detonating the primer, causing the detonation of the propellant, thereby increasing the pressure of the cavity and causing the two projectiles to separate after the projectile assembly leaves the bore of the weapon. The burning of the propellant releases a base bleed gas that reduces the drag experienced by the anti-personnel projectile.

  • Patent number: 8640589
    Abstract: A method of modifying a projectile includes removing material from an aft end of the projectile, and coupling a device to the aft end. The method may be used to convert a spin-stabilized projectile into a fin stabilized projectile, by modifying the aft end of a spin-stabilized projectile to accept a fin kit. The modifying may involve removing material with lathe, and may include forming external threads on the aft end that may engage corresponding internal threads on the device, to effect the coupling of the device to the aft end. The modification method allows versatility in employing projectiles, including existing stocks of projectiles. In particular the method allows spin-stabilized projectiles to be converted to more accurate fin-stabilized projectiles.

  • Patent number: 8578856
    Abstract: The decomposition of a projectile in a target body, particularly a hunting projectile in wild animals after penetration therein, determines the energy output of the projectile and thereby the effect of the shot. For projectiles with double cores, the properties of the ingredients used in the cores decisively affect the decomposition and particularly the deformation behavior of the cores. According to the invention, a partial decomposition projectile comprising two cores is provided with one solid core (3) made of a material suited to said projectile and the other core (4;22) is divided up into two areas (4a,4b;22a;22b), whereby one area (4a;22a) is made of ball-shaped elements made of a metal material granulate (5;23) and the second area (4b;22b) is made of a metal or ceramic powder and the ball-shaped elements or granulates (5;23) are pressed to become free of shrink holes, in order to improve decomposition behavior control.
