摘要: A detonator for a hand grenade fuze comprises a detonator case; a slider that is transversely reciprocable in the detonator case from an unarmed position to an armed position, the slider including a longitudinal through-hole filled with a primary explosive; a spring that biases the slider to the unarmed position; an arming mechanism attached to the slider, the arming mechanism comprising a shape memory alloy; an explosive lead disposed below the slider; and a booster charge disposed below the explosive lead.

摘要: The present invention discloses a process for the on-demand production of small quantities of lead azide. First, a metered quantity of sodium azide solution and a metered quantity of a solution of a lead salt sufficient to react with the sodium azide are introduced into a T-mixer or Y-mixer. Then, the sodium azide and lead salt solutions are conveyed into a static mixer and the azide and lead compounds are permitted to react together, forming insoluble crystals of lead azide as a slurry in an aqueous medium. The lead azide crystals are then separated from the aqueous medium. The process is carried out within an explosion-proof chamber.

摘要: A lead-free primer energetic composition including Cyanuric Triazide (60%), Tetracene (5%), Barium Nitrate (20%) and Antimony Trisulfide (15%) is produced. The lead-free primer energetic composition is used to construct a primary detonator including a transfer charge of Cyanuric Triazide, which produces a further initiation train that may subsequently detonate a secondary explosive, i.e., HDX, RDX, or a pyrotechnic device.
