Low-Energy Flying-Plate Detonator

摘要

A low-energy, hot-wire detonator has been developed in which a flying plate is employed to achieve detonation. A relatively spark insensitive pyrotechnic, titanium subhydride potassium perchlorate, TiH sub 0 sub 68 /KClO sub 4 , is used as the ignition material. The thermally stable secondary explosive hexanitroazobenzene (HNAB) serves as the donor propellant to accelerate an aluminum flyer. Flyer velocities of 1.3 km/s have been achieved at 10 mm of displacement at -55 exp 0 C. The detonator will function at -55 exp 0 C with a 5.0 ampere constant current firing pulse. This paper presents the design criteria and the functional characteristics of the flying plate. A summary of the detonators electrical and environmental characteristics is also presented.
