Fuseless explosive propellant cartridge

摘要

An explosive propellant cartridge for use in propellant-actuated devices. The cartridge contains only the explosive propellant which is stable and safe when not confined in a vessel capable of high pressure containment and does not contain the less stable fusing element. The propellant is contained in an annular space between concentric tubes with the inner tube being perforated. An elongated fusing element is inserted into the inner tube after the cartridge is secured in the propellant-actuated device.
