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...
