Abstract: In a shell thrower, a grenade is inserted in a barrel and a booster charge under the grenade will fire and generate a gas pressure which forces the grenade out of the barrel. To improve the driving charge acting on the grenade, a pressure plate is detachably fixed under the grenade, and the booster charge is located on the underneath side of the pressure plate. An ignition mechanism for the booster charge is arranged on the underneath side of the pressure plate, which ignition mechanism is initiated by the impact of the pressure plate against the bottom or a shoulder of the barrel. A releasable engagement is arranged between the upper side of the pressure plate and the bottom of the grenade, which engagement includes a locking device, which is released from its locking position by a part of the driving pressure of the booster charge.

Abstract: A single-use firing indicator device for a projectile having a hollow rear extension includes a stopper and an indicator member. The stopper is shaped to at least partially cover the rear extension of the projectile. The indicator member is connected to the stopper and may secure the firing indicator device to the projectile. Removing the firing indicator device to prepare the projectile for firing requires permanently deforming the indicator member. As a result, the firing indicator device reliably conveys the firing status of the projectile without requiring costly modification or added parts.

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.

Abstract: The projectile (1) comprises a head (3) and a tubular tail section (4) carrying fins (5). A piston (6) is fitted inside the tail section so as to form, with the walls of the latter, a closed combustion chamber containing a propellent charge (7). The launching means comprise a cylindrical launching rod (2) which is mounted on a support (12). The rod (2) is hollow and contains a percussion member comprising a percussion pin (14) fast with a percussion rod (13). For launching the projectile, the latter is positioned on the launching rod (2) so that the end of this rod is engaged in the opening of the tubular tail section (4). The free end of the tail section is then centered in relation to the launching rod (2). When the ends of the launching rod (2) and of the piston (6) then come into contact, a centering is likewise produced at this level, because of the cooperation between the guiding surfaces (2') and (6').
