ABSTRACT:
Apparatus for a gas charged and initiating mechanism launches a projectile f a relatively low mass at a low velocity. The apparatus has a chamber which has an opening at one end. A burst diaphragm is seated within this opening and seals it. The opening also houses the projectile. A check valve is mounted in an aperture at the opposite end of the chamber. The compressed gas is charged through the check valve. The bursting of the diaphragm is accomplished by a pointed rod protruding from the rear of the projectile or by an electrically-powered squib associated with the diaphragm. The bursting of the diaphragm provides a quick-acting means for releasing the compressed gas whereby the projectile is accelerated down the barrel of a weapon. Additionally, a safety device is mounted within the cartridge for preventing the accidental functioning of the launching projectile.
