DE102006008309A1 - Grenade producing infra-red emitting, visually-opaque smoke preventing hostile targeting, comprises modular blocks generating smoke quickly and burning over protracted interval - Google Patents

Abstract

A body (14) of the main charge (12) comprises two blocks (16, 18). Each block is designed for a particular effect. The first block (16) rapidly generates smoke. The other block (18) burns for a protracted interval. Each block is formed by a stack of smoke tablets (20, 22). The tablets comprise individual rings or are multi-part, comprising ring segments. The blocks are welded into a plastic sheet (24), which is blown-open pyrotechnically. Self-adhesive black powder films, i.e. tape matches, are wound around each of the individual blocks (16, 18) forming the main charge (14). Second black powder films are wound around the combined main charge (14). The two films are offset relative to each other.

Description

These The object is achieved by the Characteristics of claim 1 solved. Preferred embodiments or further developments of the inventive smoke projectile are in the subclaims characterized.

Of the forms inventive smoke projectile a quick-fog throwing body with a modularly constructed smoke body, which has two different active bodies, where the one active body causes a temporally fast fog construction and the other active body one has long burning time. By combining the two active bodies, i. through the modular structure of the smoke body, consisting of the two different active bodies, is thus advantageously a fast fog construction within short Time, coupled with a long burning time, achieved. This leads in an advantageous manner Way both to a relatively long visual coverage as well to a comparatively long infrared coverage. The guarantee This advantageous properties is due to the one active body the fast fog construction and the other active body with the relatively long Burning time and by appropriate quantity adjustment of fog tablets the two active bodies reached.

The two active bodies are preferably welded in a plastic film, the pyrotechnisch is separable. After the pyrotechnic separation the plastic film are the individual fog tablets of the two submunitions separated.

To the Separating the plastic film are self-adhesive black powder films, so-called Tapematch, provided. It is preferred if first Black powder films are applied individually to the two active bodies, and if second black powder films around the two different submunitions having modular fog body are applied, wherein the first and the second black powder films offset from each other to ensure safe separation of the plastic film to ensure.

Of the inventive smoke projectile has with at least the same spontaneity as well-known Nebelwurfkörper the initially mentioned type a longer Burning time and thus a longer one Life of the fog on. With the quick-release foggear invention are armored and unarmoured vehicles improved against discovery, Capture and tracking and consequently against a threat missile protected. Another advantage is that through the simple modular Structure of the quick-release sprayer according to the invention inexpensive to produce is.

at the quick-release sprayer according to the invention is at the parts that expelled be dispensed with metal parts, so that when ejecting the modular constructed fog body no metal parts that can cause injury in the area of your own Troops are spent.

One embodiment of the smoke projectile according to the invention is cut longitudinally in the accompanying drawing and will be described below.

The figure shows an embodiment of the smoke throwing body 10 with a pyrotechnic active charge 12 , which is intended to produce an infrared emitting and a visually opaque mist. The Wirkladung 12 is from a modular structure 14 formed, the two different active bodies 16 and 18 having. The active body 16 causes a temporally fast fog and the active body 18 has a long burning time. This leads to a prolonged visual coverage and at the same time to a longer IR coverage than with known smoke projectiles.

Each of the two active bodies 16 and 18 is each by stacked fog tablets 20 respectively. 22 educated. The fog tablets 20 . 22 can be integrally formed ring-shaped or multi-part ring segment.

The active body 16 . 18 are in a plastic film 24 welded, which is pyrotechnic separable. For separating the plastic film 24 Self-adhesive black powder films, so-called tapematch, are provided.

The of the active bodies 16 and 18 Modular fog body 14 is in a can 26 arranged a floor 18 and one from the ground 28 wegstehende wall 30 has, which is designed as a cylindrical sleeve. Between the ground 28 and the active body 16 is a density driving mirror 32 intended. With the reference number 34 is a lighter for the modular structure of the smoke body 14 designated.
