Abstract: A delay fuse for a warhead (1) including at least two charges (3, 8) for sequential detonation disposed inside a casing (2). The delay fuse comprises a screen (6) movable in a longitudinal axial direction inside the casing (2) and under the effect of the first charge detonating, from a starting position to a destination position in which it acts on control means (12) for firing a second charge. The fuse includes a component of compressible material (13) disposed inside the casing between the screen (6) and the control means (12). The invention is applicable to shells, rockets, or missiles.

Abstract: The technical sector of the invention is that of explosive charges with a re-forming coating. This explosive charge is characterized by the fact that the coating includes two superimposed and contiguous plates. The plate in contact with the air has a lower density than that of the plate in contact with the explosive matter, and its compressibility is less than or equal to 50% under a pressure of 50 Gigapascals.

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.
