Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
114 words
A projectile including a fuze for sensing a predetermined position in the trajectory of the projectile, a nose element, first expelling means for discarding the nose element in response to said sensing of said predetermined position in the trajectory of said projectile, at least one subprojectile, and second expelling means for expelling said at least one subprojectile from the projectile, said projectile further comprising deceleration-sensing means for sensing a predetermined first level of deceleration forces which affect the projectile as a consequence of said discarding of the nose element, and initiation means responsive to the sensing of said first level of the deceleration forces for actuating the second expelling means to expel the subprojectile.
Claim 2
Dependent Claim
114 words
A projectile including a fuze for sensing a predetermined position in the trajectory of the projectile, a nose element, first expelling means for discarding the nose element in response to said sensing of said predetermined position in the trajectory of said projectile, at least one subprojectile, and second expelling means for expelling said at least one subprojectile from the projectile, said projectile further comprising deceleration-sensing means for sensing a predetermined first level of deceleration forces which affect the projectile as a consequence of said discarding of the nose element, and initiation means responsive to the sensing of said first level of the deceleration forces for actuating the second expelling means to expel the subprojectile.
Claim 3
Dependent Claim
75 words
A projectile in accordance with claim 1, further comprising a second subprojectile, third expelling means for expelling the second subprojectile from the projectile, second deceleration-sensing means for sensing a predetermined second level of the deceleration forces which affect the projectile due to said expelling of the first subprojectile, and second initiation means responsive to the sensing of said second level of the deceleration forces for actuating the third expelling means to expel the second subprojectile.
Claim 4
Dependent Claim
60 words
A projectile in accordance with claim 2, wherein said predetermined second level of the deceleration forces exceeds said predetermined first level of the deceleration forces, and said predetermined second level of the deceleration forces is so chosen that it is not reached by the deceleration forces which affect the projectile as a consequence of said separation of the nose element.
