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 invention relates to an airburst hand grenade. Existing constructions of fragmentation grenades all have one basic shortcoming; the active fragments are very unlikely to find the target owing to the fact that detonation takes place with the hand grenade lying on the ground, whereby the effect does not occur. The invention solves the above problem by a hand grenade being caused to jump 1-2 m above the ground before detonating. This means that the fragments will be spread essentially horizontally and at an angle (v) to the ground and consequently attack the target from above, which results in a many times larger target surface and the capability of spreading fragments behind a shelter. The hand grenade comprises a mechanism (1), a detonator (2), a warhead (14) and support legs (9) for raising the hand grenade from a horizontal position to an upright position.
