Patent number: 7047887Abstract: 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.Type: GrantFiled: October 11, 2002Date of Patent: May 23, 2006Assignee: Forsvarets MaterielverkInventor: Ian Kinley
