The present disclosure relates to a pyrotechnic object, in particular an irritation body, irritation projectile or ammunition, comprising an ignition device, comprising a delay chamber extending along a delay path, in which chamber a delay charge is accommodated, and comprising at least one and preferably a plurality of effect chambers in which or in each of which an effect charge to be ignited is accommodated, wherein the delay chamber is transversely connected to a respective effect chamber via a respective over-ignition opening which branches off from the delay chamber and forms an over-ignition path, wherein in the case of a plurality of effect chambers the plurality of over-ignition openings are arranged successively downstream along the delay path in the order of the effect charges to be ignited.

Pyrotechnic object

The invention relates to an igniter with a delay time (Vz) that can be set. The delay time (Vz) can be fixedly defined, or individually and situation-dependently set on-site. In particular, the invention relates to a delay time that can be set for a stun grenade, a hand grenade etc., with options for the individual setting and situation-dependent or situation-contingent customisation of the delay time (Vz), and consequently of the effect of the active compositions in-situ. In order to achieve individual setting options, the invention proposes that at least two different delay times (Vz) can be set. To this end, the igniter has, in a delay section, preferably in the fuse head, a relief bore that can be closed or opened.

Igniter with a delay time that can be set

A pyrotechnic delayed-action composition and primer charge made of REACh-compliant components that are safe for humans and the environment. The delayed-action composition comprises at least one oxidant, at least one reducing agent, at least one filler and at least one mineral binder. The performance parameters thereof, in particular the burning time, can be set variably within a wide range. The composition clinkers on its own, thus preventing extinction at the front of the burning material even in dynamic conditions. The primer charge comprises at least one oxidant, at least one reducing agent, at least one filler and at least one mineral binder. It is easy to ignite and, due to its clinker structure, transfers its energy well to the compositions to be ignited. The delayed-action composition and the primer charge have the same structure and can easily be combined and adapted to each other in delayed-action units.

Reach-compliant pyrotechnic delayed-action composition and primer charge having variably settable performance parameters

A powdery pyrotechnic mixture is proposed that comprises a binary or ternary inorganic oxidizing agent mixture composed of one or two metal oxides, a nitrate totaling 50.0% by weight to 85.0% by weight, an elementary inorganic fuel or a mixture of elementary inorganic fuels totaling 15.0% by weight to 40.0% by weight, a stabilized nitrocellulose or a nitrocellulose-based propellant powder from 0.0% by weight to 25.0% by weight, graphite from 0.0% by weight to 5.0% by weight as well as. Optionally. a further processing aid from 0.0% by weight to 5.0% by weight. The powdery pyrotechnic mixture excels in that it contains no chlorate-containing compound and/or perchlorate-containing compound as an oxidizing agent and no sulfur or a sulfur-containing compound as fuel. The proposed pyrotechnic mixture is used in pyrotechnic objects and ammunition for the production of a bang-effect and/or flash effect.

Perchlorate-free pyrotechnic mixture

The invention relates to pyrotechnic primer charges produced on the basis of metal powders or metal hydride powders, potassium perchlorate and binders. In order to obtain a homogenous mixture, the powdery components are mixed with a liquid dispersing agent in a suspension with the aid of ultrasound and dosed having said consistency. Mixing for obtaining a suspension can also be carried out directly in a casing receiving the pyrotechnic primer charges.

Method to produce pyrotechnical igniting mixtures

The invention relates to an electrothermal ignition device for igniting a powder propellant charge ( ), which comprises at least one electrically-conductive wire ( ), that extends, at least partially, through the propellant charge, and can be connected to a current source ( ). The electrically-conductive wire ( ) is coated with a pyrotechnical ignition mixture ( )so that the ignition device can have a low electrical-energy requirement and be easily adapted to the different requirements placed on it. A mixture on a potassium perchlorate-zirconium (KClO &mdash;Zr) base has proven to be an advantageous ignition mixture.
