Abstract

Active body (2), comprising a plurality of successively arranged or stacked flares (3, 4) as an active mass in particular for the production of decoys, wherein the active body (2) surrounded by a plastic-like container (1) and a Anzündübertragungsschicht (9) at least between the Inner wall of the container is integrated.

Description

The invention is concerned with a combustible active mass container on plastic film base.

RF (Chaff) and IR sham targets and / or grenades are used in military applications to protect infantry, artillery, land-sea and air vehicles. These products are classically designed so that in a solid mass container or containers, z. B. aluminum can, the actual effective mass (WM) and a central ignition or Zerlegeladung are enclosed. The latter are used to disassemble the container as well as the ignition and distribution of the active materials. The containers form solid remains in the environment.

A known alternative is to cover the Einzelflares, which form the active body with a film so that thereby a package is laced.

The DE 25 27 205 C2 relates to a container with a plurality of defensive elements. The container here is a thin-walled cylindrical plastic container which has a wall provided with predetermined breaking points and radially rebounds during the spinning process to release the elements. In the container, a pyrotechnic propellant charge is provided with an adjustable timer.

The DE 26 02 815 A1 discloses a radiating objective bait and a method of deflecting a missile, wherein the missile guidance system is controlled by infrared radiation. The elementary bait has, in an airtight and floating housing oriented housing, a liquid aerosol and a core of a pyrotechnic compound high calorific value and a device for controlling the ignition of the core.

From the DE 83 28 479 U1 For example, an envelope for a propellant charge is known, wherein the envelope is formed from a thermoplastic film and assigned. This propellant is dimensionally stable for handling, since the pressure of the environment compresses the propellant charge powder. This also makes it possible to strap covers of multiple propellant charges with a foil. When shooting the film burns. A plastic is provided which contains the oxygen necessary for the combustion, whereby the shell is at the same time energy-supplying.

The DE 69 14 412 U relates to a container of combustible materials, such as nitrated cellulose, for fuel charges.

With the DE 198 30 262 A1 An apparatus and method for electrical ignition with reusable holding bodies for pyrotechnic fireworks and a method for their production is published. A first retaining element consists of glass, ceramic, plastic, plastic, wood, cardboard, paper, etc. with embedded resistance wire bridges and holding element, which can be replaceably fastened in a second holding element. In the first holding element is attached by means of a shrink tube either at least one conventional fuse or other ignition material.

The DE 38 10 355 A1 deals with a gas generator in which each igniter mixture is surrounded by a thin shell and is connected to the fuse line stationary. The melting temperature of the thin shell is below the burning temperature of the fuse.

The DE 32 28 736 A1 relates to an ammunition with plastic outer sleeve, in which an electrically conductive layer is arranged to protect against the increase in the protection against electromagnetic radiation within the wall of the outer shell.

Of the DE 28 11 016 C1 is a throwing body removed, the litter container consists of a deep-drawn aluminum can, the bottom is reinforced designed as a mounting plate. The throwing agent consists of circular sector-shaped leaflets, which are arranged in the throwing agent container radially around a Zündzerlegereinheit around.

In a parallel application of the applicant, a combustible active body shell is proposed, wherein the active body is not wrapped with a film or the like but these are encapsulated. The encapsulation takes place here, for example in the form of a shell, etc., the ignition behavior of the active material or the components supported. The ignition can take place on the one hand over the surface of the active body or by a centrally located ignition along the longitudinal axis. The spectral properties of the combustible shell can be optimized by incorporating materials to alter the reflection / absorption properties. In particular, the coupling of laser radiation can thus be improved and the ignition speed can be increased.

Here, the invention has the object to show a body, which also has a residue combustible shell.

The object is achieved by the features of claim 1. Advantageous embodiments are reflected in the dependent claims.

The invention is based on the idea to provide a Wirkmassencontainerkonzept that allows an ignition of the active materials from the outside. At the same time he should protect the active substances (decoy) against environmental influences, such as moisture, dust, dirt, during storage, transport and handling. The special material selection with appropriate additives allows the activation of the active materials, for example, thermally, inductively, or by means of laser, etc. when optimizing the activation.

The effective mass container concept is that a plastic film, if necessary also shrinkable, is used to create the container. The stacked Einzelflare- disks are incorporated (embedded) in the plastic film, which then glued lengthwise, verscheißt or the like connected or shrunk onto the discs. On the front pages plastic discs or films are placed, which are also glued or welded. This creates a spoiler lip that favors the opening of the decoy during combustion, hermetically sealing the container, d. h., It is hermetically sealed and thus ensures the necessary protection against environmental influences. The material selection (material selection) and the structure of the active body ensure residue-free combustion or complete conversion.

Reference to an embodiment with drawing, the invention will be explained in more detail. It shows.
