    Abstract: The present invention relates to a hand grenade comprising a main body (10), an actuator (14) releasably fixed to the main body (10), an actuator-ejection mechanism, and a charge to be released, which includes an automatic-identification device (34) embedded in the actuator. The invention further relates to a grenade actuator of the EOT-type (Espoleta de Ogiva de Tempo, time fuse point), which comprises an automatic-identification device (34) embedded therein. The present invention can also materialize in the form of a method of manufacturing a hand-grenade actuator, according to which it is provided a housing for an automatic-identification device in the actuator body. Indeed, the method of manufacturing the actuator further includes providing said housing with a cylindrical shape and then inserting an equally cylindrical automatic-identification device into said housing.

  • Patent number: 8857341
    Abstract: A more IM compliant grenade fuze assembly includes a fuze body, an energetics train disposed in the fuze body, and a striker lever rotatably attached to the fuze body. A spring-loaded rotor assembly is rotatably fixed to the fuze body. The rotor assembly includes a primer. A firing pin is disposed in one of the rotor assembly and the fuze body. Placing the primer in the rotor assembly decreases the area of the fuze assembly that is vulnerable to initiation by impact from a bullet, fragment, or shape charge.

  • Patent number: 7047887
    Abstract: An airburst hand grenade constructed so as to jump 1–2 m above the ground before detonating. The hand grenade includes a detonator, a warhead, and support legs for raising the hand grenade from a horizontal position to an upright position once it has landed after being thrown. The detonator includes a delay unit, an upper charge which releases the support legs, a jump charge which propels the warhead into the air, and an explosive cartridge which initiates a main charge. Because the grenade detonates above ground, the fragments are spread essentially horizontally and at an angle to the ground and consequently attack the target from above, which results in a much larger target surface and the capability of spreading fragments behind a shelter.
