Burping projectile

Abstract

The present invention provides a burping projectile and, particularly, a non-lethal projectile having a nose-mounted fuze thereon, which initiates an expulsion charge via an ignition shaft in the payload cup of the projectile body at a preset distance from target impact, resulting in sufficient expansion of the projectile body via the forces of propellant gases to create an annular opening between the projectile body side wall and projectile body forward end. The payload is then ejected from this annular opening, the resulting forward velocity of the escaping payload producing a rearward thrust on the projectile, and a concomitant deceleration thereof to a non-lethal forward velocity or a total reverse in direction of travel.

Description

FIELD OF THE INVENTION[0001]The present invention relates in general to a burping projectile. In particular, the present invention provides a non-lethal projectile, having a nose-mounted fuze thereon, which initiates an expulsion charge via an ignition shaft in the payload cup of the projectile body at a preset distance from target impact, resulting in inflation of the projectile body with propellant gases to a level sufficient to expand same so as to create an annular opening between the projectile body side wall and projectile body forward end. The non-lethal payload is then ejected from this annular opening, the resulting forward velocity of the expelled payload and propellant gases producing a rearward thrust on the projectile, and a concomitant deceleration thereof.BACKGROUND OF THE INVENTION[0002]Conventional non-lethal ammunition is launched with a kinetic energy sufficiently low to effect a non-lethal result upon target impact. To enable launching of ammunition at such reduc...

Problems solved by technology

However, when utilizing non-lethal munitions, such as grenades, there is a danger that, even with reduced muzzle velocities, the projectile body itself may have sufficient kinetic energy to severely wound or damage a human target upon impact.

Further, when utilizing non-lethal munitions, such as non-lethal grenades, against inanimate targets, such as automotive windshields, etc., there is a danger that the projectile body will have sufficient kinetic energy upon impact to penetrate the target and harm surrounding human assets.

Further, by reducing muzzle muzzle velocity, recoil impulse is also reduced, which frequently causes malfunctioning of the weapon operating system and fire control when firing the non-lethal ammunition from standard weapons.

In addition, conventional non-lethal munitions are not range specific, i.e., they are meant to be used for targets within a wide range from the shooter, and are not tailored to targets within specific ranges.

Frequently, such conventional non-lethal munitions fail to reach reduced velocities (and thus reduced kinetic energies) before impacting the target, when the target is at a close proximity from the shooter, or are incapable of reaching targets at longer ranges, due to reduced velocities / kinetic energies at such longer ranges.

However, in combat situations, adherence to such guidelines is difficult and often overlooked.
