A detonation transfer assembly is disclosed. A detonation transfer assembly may comprise an external casing comprising an input end and an output end axially opposite the input end, an explosive column spanning axially inside the external casing, a primary explosive disposed within the explosive column, and a secondary explosive disposed within the explosive column axially between the primary explosive and the output end. The primary explosive and/or the secondary explosive may comprise a thermally insensitive initiation material that resists at least one of detonation or thermal degradation in response to temperature increase rate of 3.3 C. per hour over at least twenty hours.

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.

The present disclosure relates to a trunkline delay detonator and a blast-triggering device using the same. In the blast-triggering device, a trunkline delay detonator is inserted into a connector in such a manner that a plurality of shock tubes connected to a detonator for initiating an explosive are interposed between the connector and the trunkline delay detonator, so that an explosion signal is applied to the shock tubes by detonation of the trunkline delay detonator. In the blasting detonator, close contact between the outer surface of the trunkline delay detonator and the shock tubes is improved, whereby energy lost in an explosion is reduced and an explosion signal is stably and uniformly applied to the shock tubes by using powder which has a weak explosive power and is relatively insensitive compared to conventional powders.

A squib assembly for a non-electric initiator of an anti-personnel obstacle breaching system includes a housing configured to connect to the igniter of a rocket motor of the anti-personnel obstacle breaching system, a slider assembly slidably contained within the housing and configured to connect to a shock tube of the non-electric initiator, and a pyrotechnic element disposed within the housing. Upon activation of the non-electric initiator, the squib assembly is configured to mechanically puncture a base of a initiator sleeve of the rocket motor and to thermally initiate ignition of the rocket motor.

The present invention relates to a nano-energetic material (nEM) composite having ignition and explosion characteristics by a low-power laser pointer beam and capable of being remotely and optically ignited by adding black powder to nEM composite powder, and a method of preparing the same. The nEM composite includes: nEM composite powder; and black powder used as a mediator for initial ignition to initiate ignition in response to a laser pointer beam and cause a nEM to be continuously ignited and consecutively explode by ignition heat.
