Abstract

Abstract

Detonators based on laser-driven flyers are less vulnerable to the strong electromagnetic interference and can use insensitive secondary explosives as initial explosives. Additionally, this technology has advantages in terms of improved flexibility and reliability. Hexanitrostilbene (HNS-Ⅳ) is the ideal candidate for use in laser-driven flyer initiation. Experiments were carried out to study the initiation of HNS-Ⅳ with the density of 1.5 g/cm³, by using laser-driven Al/Al₂O₃/Al multi-layer flyers and Al single-layer flyer at different laser energies. Within 217-245 mJ laser energies, the HNS-Ⅳ can be successfully detonated by Al/Al₂O₃/Al multi-layer flyers, while not be detonated by Al single-layer flyers under the above laser energies.
