Abstract
The technical area of this invention is initiation delay mechanisms for warheads carrying two tandem-mounted shaped charges. With this invention the initiation delay mechanism consists of using the movement of a screen placed between the forward charge 1 and the rear charge 2. According to a specific characteristic, as it moves, the screen can close an electric circuit by means of contactors placed in a given position. According to other variants, the screen can impact piezoelectric components generating energy or, in the case of a magnetic screen, can cross an induction coil. Application in the field of projectiles and, particularly, of rockets and missiles.
