Abstract: Examples of safety devices for use with a munition are provided, the munition including a munition explosive and a safe and arm (S&A) device for activation of the munition explosive. In some examples the safety device includes a switch member and an actuation mechanism. The switch member is configured for being disposed between the munition explosive and the S&A device, the switch member being movable between at least two switch positions. In a first switch position (an arming prevention position (APP)), arming communication between the munition explosive and the S&A device is prevented. In a second switch position (an arming enabling position (AEP)), arming communication between the munition explosive and the S&A device is allowed. The actuation mechanism is configured for selectively moving the switch member at least from the APP to the AEP to thereby enable the S&A device, when armed, to detonate the munition explosive via the switch member.

Abstract: A stun grenade for individual adjustment and situation-dependent adaptation of the number of active masses in situ. A switch mechanism is built into the stun grenade, enabling the simultaneous activation of different chambers inside the stun grenade in order to adjust the effect. The switch mechanism is formed by a tube and peripherally integrated boreholes and grooves. A different number of the chambers in the stun grenade is activated by the switch mechanism, thereby increasing or decreasing the active power.

Abstract: A fuse mechanism for e.g. a pyrotechnic grenade in which a spring loaded striker lever (31) is blocked via a cammed surface (22) of a safety lever (21) comprising a handle. (25). Release of the handle (25) enables deployment of the fuse assembly. Spring-loaded striker lever (31) is urged upwards by the force of torsion spring (38). Contact between the free end (34) of the striker lever (31) exerts a rotational force on cammed portion (22). The safety lever (21) rotates away from the body of the munition (20). Rapid upward movement of the striker lever (31) is prevented at this stage by contact of the free end (34) with the cammed portion (22). Further rotation of the safety lever (21) occurs until point where the cammed portion (22) is no longer in contact with the striker lever.

To reliably avoid an unintentional detonation of the rocker arm detonator prior to its proper use, when the rocker arm detonator is not in use, the firing pin spring is in its untensioned state and may be tensioned by a separate tensioning lever as soon as the rocker arm detonator is to be properly deployed.

The chamber (10) in the lower module (102) can, depending upon module (102), be selected in different sizes, which produces, under concomitant volume variability, output variability with defined increase in output.

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.

Abstract: The improvements are applicable to fuses provided with a container (9) inside which may move axially a slider (10) having an electrical generator (1), the activation of which provides the electrical energy required for the operation of the fuse, delivering this energy to an electronic circuit (11) which discharges on a detonator (8), which causes the detonation which through a multiplier (12) is transmitted to the explosive charge of the grenade. The novelty consists in that two electronic timers are provided which are mutually independent and which may operate under different or identical technologies, one analogue and the other digital, and in that the detonator (8) and the multiplier (12) in a resting position are unaligned, with alignment resulting from a displacement caused by a specific arrangement of the elements of the explosive chain.

Abstract: The locking and stabilizing device for grenades utilizes a solid nylon ring and multiple nylon ribbons that are attached to the ring at regular intervals around its circumference. During storage, the ring surrounds and locks the slider of the grenade in its storage position. But upon deployment, under aerodynamic forces the ring moves away from the slider, releasing the slider. When the slider is thusly released, it slides out and brings the detonator in place to be impacted upon by the pin when the grenade hits the target, thus detonating the grenade. The multiple ribbons extending from the ring unfurl due to the aerodynamic forces and provide stability to the grenade flight.
