Abstract
A separate explosive charge within a cartridge is detonated to initiate motion of a projectile and effect delayed ignition of a larger volume of primary propellant. Steady burning of the ignited primary propellant after motion of the projectile is initiated, continues its propulsion with a pressure/displacement profile.
Claims7
An ammunition round, comprising:
- a cartridge casing having a closed rear end and an open front end;
- a projectile located within said open front end of said cartridge casing;
- a detonator located in said closed rear end of said cartridge casing;
- a tube extending axially from the detonator to a base of the projectile;
- a detonating explosive extending axially from the detonator within said tube;
- a gas filled space, surrounding said detonating explosive, between said detonating explosive and said tube;
- a body of propellant located between said tube and said cartridge casing whereby upon detonation of said detonating explosive, by said detonator, gas pressure is generated which initiates movement of said projectile independently of said body of propellant and provides for a delayed ignition of the body of propellant to continue said movement of the projectile.
