Definitions

  • the invention is referring to a self disarming fuze that can be used in grenades of artillery cargo munition, as well as in rotating mortars, bombs, and rockets.
  • the unexploded grenades are dangerous for the troops that will go through the bombarded areas, as well as for the field cleaning personel.
  • the armies that are currently using cargo munitions demand the use of a fuze, for the grenades, that will be self-destructive in the case that they will not operate, for any reason, after the impact on the target.
  • the described fuze, that constitutes the opject of the invention is self disarming, in the occasion that it will not operate after the impact on the target, making the grenade entirely harmless.
  • the fuze For the rare occasion that the fuze will not operate explosively and it will not self disarm after the impact of the grenade on the target, the fuze is again harmless for the troops that will go through the field and accidentally step on a grenade.
  • the detonator (7) and the striker (3) are off line.
  • the slider (2) cannot move in the armed position, because the end of the striker (3) is inside an opening of the slider (2),and retained in this position by the safety (5).
  • the entire system of the slider (2) and the striker (3) and the safety (5), is inside the shell (1) and enclosed with the metal plate (11).
  • the fuze is shown in the armed position.
  • the safety (5) of figure 1 is separated and the striker (3) has been retracted from the slider (2) because of the expansion of the spring (4) of figures 1 and 2.
  • the slider (2) because of the centrifugal force, has moved in a way that the detonator (7) is on line with the striker (3) making the spring (6) be compressed.
  • the upright position of the grenade during the fall is assured by the ribbon (13), that is firmly attached on the top of the fuze with the metal straps (9) and (14).
  • the metal straps (9a) and (9b), in the ribbon ends, during the rotation maintain the ribbon in an almost horizontal position, simulating in this maner the helicopter blades.
  • the metal straps (9a) and (9b) can be omitted if the ribbon, when rotating, has enough weight to maintain its horizontal position during the rotation of the grenade.
  • figure 3 side view
  • the striker (3) because of the inertia, has struck the detonator (7), causing its explosion.
  • the slider (2) is shown in top and side view.
  • location (1) the detonator (7) of figures 1,2,3 is placed.
  • location (3) the end of the striker (3) figures 1,2,3 is inserted when the fuze is in safe position.
  • the groove (4) is making the movement of the slider (2) easier during the arming procedure.
  • the movable cylinder or sphere (6), is located in groove (5).
  • the reason for the cylinder of sphere (6) is to maintain the slider (2) in armed position when the spin of the fuze is reduced or stopped.
