ABSTRACT:
A projectile propellant device is adapted to supply a compressed gas from a compressed gas container for providing the propulsion force for a projectile or for providing the operating force for a gas powered device. The propellant device includes a gas container containing a volume of gas at sufficient pressure for applying a desired force upon release, and a compressed gas releasing structure for producing a release opening in the compressed gas container in response to the detonation of a pyrotechnic material. The release opening releases the compressed gas for applying the desired force, such as a propulsion force to propel a projectile. The gas releasing structure preferably includes a pyrotechnic charge device and a puncturing device both mounted within a suitable device housing along with the gas container. The pyrotechnic charge is adapted to be detonated preferably through an electrical discharge to force the puncture device into the compressed gas container to puncture or otherwise form the gas release opening to release the gas from the gas container.
