ABSTRACT:
A ballistic propulsion system of the type used to launch grenades from a rifle. The system includes a housing having a propulsion tail protion with a ballistic cartridge mounted inside and a nozzle with a rear opening having a diameter d.sub.1. This opening is surrounded by an annular seating surface having an outside diameter d.sub.2, which is larger than d.sub.1. A diaphragm is mounted in engagement with the seating surface, and the diaphragm is designed to remain intact when pressures generated by a ballistic cartridge are asserted on a surface area of diameter d.sub.1 or less, but to break away from the propulsion tail when the gas pressure is applied to a surface area having a diameter d.sub.2 or greater. As a result, the diaphragm remains intact when the projectile is first launched by gas pressure generated by a ballistic cartridge within the rifle, but the diaphragm breaks away when the ballistic cartridge inside the propulsion tail builds up sufficient pressure. The ballistic cartridge within the ballistic tail is fired at a predefined time after the initial launch, in order to increase the range of the projectile. Firing of the ballistic cartridge inside the housing is achieved by means of a sliding, dual-action mechanism, which is spring loaded and has a firing pin at either end. Upon initial launch, the lower firing pin is driven downward by inertia to ignite a delayed charge for firing the ballistic cartridge. The upper firing pin fires the grenade, either upon impact or under the influence of gas pressure generated by the ballistic cartridge.
