  • Patent number: 4811664
    Abstract: A slider type fuse for a cargo warhead grenade. The slider is slidable in a lane normal to the axis of the striker pin and carries additional to the detonator a pyrotechnic device comprising an igniter charge, a booster charge removed therefrom and located in close proximity to the detonator, a delay charge between the two and swingable striker means which become unlocked in the armed state and are adapted to strike the igniter charge in consequence of centrifugal forces that develop in the course of flight. The delay of the pyrotechnic device is designed to outlast the flight time of the grenade. Whenever the striker does not strike the detonator when the grenade hits the target, the detonator is initiated by the booster charge of the pyrotechnic device.

  • Patent number: 4715282
    Abstract: A cluster bomb grenade having a fuse and striker pin mechanism in the rear ortion is known per se. On the rear portion there are mounted telescoping wings in a centro-symmetrical arrangement and adapted to swing from a folded to an unfolded position. There are provided retainer means cooperating with the striker pin in such a fashion that in the locking position of the striker pin the wings are located in the folded position, which retainer means are adapted to be jettisoned upon retraction of the striker pin. There are also provided stop means for arresting the wings in a desired position. When in operation the grenade is rejected from its cargo projectile the telescoping wings unfold and extend, whereby the spin rate of the grenade is gradually reduced.
