Described are energetic compositions formed of a 5,5-bistetrazole salt and a perchlorate salt, in which the energetic composition is a co-precipitated product. The 5,5-bistetrazole salt and the perchlorate salt can be dipotassium 5,5-bistetrazole and potassium perchlorate. The energetic composition can have a particle size distribution between 1-50 micron and/or a mean volume diameter of less than 30 micron. In a low energy electro-explosive device, an ignition element is at least partially surrounded by an acceptor formed of this energetic composition, and the ignition element can be a bridgewire, a thin film bridge, a semiconductor bridge, or a reactive semiconductor bridge.

Selectable Force Gas Generator
20200200511 · 2020-06-25 ·

A selectable force gas generator (SFGG) includes support material of honeycomb structure and a gas collection chamber contained in a housing. Gas-generating propellant cells are partially embedded in the support material. Each of the gas-generating propellant cells includes a steel jacket having a convex portion exposed to the gas collection chamber. The steel jacket has an orifice through the convex portion. Each propellant cell includes a propellant packet contained in the jacket. Each propellant cell includes a fire wire electrically connectable to an electrically-fired initiator and electrically connected to the propellant packet. The fire wire transmits a firing signal that causes the propellant packet to produce gas. A cap is positioned between the propellant packet and the jacket. The cap has a tip that blocks the orifice of the jacket and the thickness of the jacket is sufficient to prevent sympathetic detonation of the propellant packet.

METHODS TO IMPROVE BURST UNIFORMITY AND EFFICIENCY IN EXPLODING FOIL INITIATORS
20200191536 · 2020-06-18 ·

Exploding foil initiator apparatus, system, and method that improve the current density in the bridge region by modifying the shape and dimensions of the bridge and related components. The exploding foil initiator reduces burn-back by making areas of the bridge thicker except directly under the flyer. The exploding foil initiator boards are built so the flyer is not connected to the rest of the top cover-lay. This avoids losing energy due to the flyer having to tear away from the solid cover-lay.

Microwave ignition of energetic material housed within a gun

The systems and methods for microwave ignition of energetic material housed within a gun (e.g., primers and/or propellants) allow for the use of insensitive energetic materials and/or insensitive gas-generating materials in place of sensitive energetic materials relied upon by mechanical ignition systems. In some embodiments, the use of insensitive energetic materials and/or insensitive gas-generating materials increase the safety and reliability of guns that would otherwise need to depend on sensitive energetic material required by mechanical or laser ignition mechanisms. Additionally, in some embodiments, the systems and methods provide greater versatility with respect to the variety of energetic materials that may be employed within guns.

SYSTEMS AND METHODS FOR IGNITION IN A CONDUCTED ELECTRICAL WEAPON

A conducted electrical weapon (CEW) deploys wire-tethered electrodes after generation of an ignition signal. The ignition signal is provided to a deployment unit. The deployment unit includes a primer material adjacent a conductor. The conductor conducts the ignition signal outside the primer material. A temperature of the conductor increases in response to receiving the ignition signal. The primer material ignites in response to the increase in temperature of the conductor.
