  • Method, computer program and weapons system for calculating a bursting point of a projectile
    Patent number: 11940249
    Abstract: A method is provided for calculating the bursting point of at least one projectile fired at a target object, involving measuring the position of the projectile, estimating the position of the projectile, estimating the speed of the projectile, measuring the position of the target object, estimating the position of the target object, estimating the speed of the target object, calculating optimal bursting points for the projectile based on the estimated position of the projectile, the estimated speed of the projectile, the estimated position of the target object and the estimated speed of the target object, and communicating the bursting points for the projectile to the projectile. A computer program, a computer system, and a weapons system are also provided.

  • Warhead
    Patent number: 11187508
    Abstract: A warhead includes an outer casing and an inner shell, which delimits a central space for an explosive substance. The inner shell receives a series of preformed elements, which are arranged in contact with the outer side of the inner shell. The inner shell is arranged for a controlled fragmentation upon a detonation of the explosive substance. The preformed elements are arranged with a surface contact against the inner shell.
