Abstract
A shaped charge and projectile combination for firing from a weapon, the combination including projectile (3), shaped charge (1) of high explosive material and metal liner (2) located between charge (1) and projectile (3). Charge (1) includes detonator (6) and cavity (4) in an external face facing the muzzle of the weapon, cavity (4) being shaped to axially concentrate explosive on detonation of charge (1) towards the rear (5) of projectile (3). Metal liner (2) forms a jet of liner material on detonation of charge (1) to impact the rear (5) of projectile (3) and so propel projectile (3) from the weapon at high velocity, typically greater than 1000 m/s and up to 6000 m/s. Projectile (3) therefore travels a flatter trajectory and has a higher penetrating power than a conventionally propelled projectile.
Claims41
A shaped charge and projectile combination including:
- a projectile
- a shaped charge of high explosive material including a cavity in an external face of the charge, shaped to axially concentrate explosive upon detonation of the shaped charge towards the projectile, and
- a metal liner between the shaped charge and the projectile, to form a jet of liner material on detonation of the shaped charge to impact the rear of and propel the projectile.
A shaped charge and projectile in combination as claimed in any one of the preceding claims wherein the projectile has a diameter which is less than the widest cross-section of the cavity in the shaped charge.
A shaped charge and projectile in combination as claimed in any one of the preceding claims wherein the liner is a ballistic disk.
A shaped charge and projectile in combination including:
- a projectile,
- a body of a high explosive material forming a charge and including an internal cavity open to one end of the charge to axially concentrate explosive force upon detonation of the shaped charge towards the rear face of the projectile, and
- a metal layer lining the interior of the cavity in the shaped charge.
A method of propelling a projectile including:
- providing a projectile,
- providing a shaped charge of high explosive material including a cavity in an external face of the charge, the cavity shaped to axially concentrate explosive upon detonation of the shaped charge towards the projectile,
- providing a metal liner between the shaped charge and the projectile, and
- detonating the shaped charge at an end opposite the cavity to form a jet of liner material, and focus the jet on the rear of the projectile so that at least a portion of the kinetic energy of the jet is transferred to the projectile to propel the projectile.
