  • Patent number: 4284007
    Abstract: Projectile with at least one expellable subprojectile. The projectile is provided with a nose element, which is arranged, in a predetermined position in the trajectory of the projectile, to be discarded, thereby causing a decelerating force on the projectile. The fore subprojectile is provided with a deceleration-sensing device, which is capable of initiating the expelling of the subprojectile as a consequence of sensing said deceleration force. The subprojectiles in behind are arranged to be expelled either as a consequence of sensing deceleration forces occurring on expelling of the subprojectile immediately in front of it, or alternatively to be expelled in a conventional way with a delay relative to one another achieved through pyrotechnic delay.
    Type: Grant

  • Patent number: 4281600
    Abstract: A subprojectile to be expelled from a projectile. The subprojectile is provided with a fuze, which has an ignition body being capable of sensing acceleration forces appearing at the expelling of the subprojectile from the projectile, and being capable of sensing deceleration forces appearing after the expelling of the subprojectile from the projectile. The ignition body is arranged to bring arming means into an armed position in response to said sensing of acceleration forces. The ignition body is capable of initiating a detonation of a bursting charge in the projectile as a result of said sensing of deceleration forces when the arming means is brought to the armed position.
