WO2010149289A1 - Combustible active mass container - Google Patents

Abstract

Proposed is an active body (2) comprising, as active mass, multiple flares (3, 4) arranged behind each other or stacked, in particular for the generation of decoys. The active body (2) is enclosed in a plastics-like container (1) such as a plastic film (5) or a shrink tube (7). Plastics disks or films (8) are placed on the end face of the container and are connected to the plastics film (5) or the tube (7) by adhesion or heat sealing (6) such that the container (1) is hermetically sealed.

Description

 DESCRIPTION

Combustible bicycle container

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 bulk container or container, 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.

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 consists in that a plastic film, if appropriate also shrinkable, is used to create the container. The stacked Einzelflare- discs 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 which, upon combustion, promotes the opening of the decoy target, hermetically sealing the container, i.e., it is hermetically sealed, thus providing the necessary protection against environmental impact. 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.

1 is a schematic representation of an active mass container with active masses,

2, 3 variants of the active mass container of FIG. 1 with concluding end faces,

Fig. 4 shows the active mass container of Fig. 2 with an ignition transfer layer.

In Fig. 1, 1 is a Wirkmassencontainer or Wirkmassenbehälter shown for receiving an active body 2, consisting of several Einzelflares 3, 4. The container 1 consists of a plastic.

Fig. 2 shows a variant of the container 1, which in this case consists of a plastic film 5. In this, the Einzelflares 3, 4 are incorporated, the film 5 glued or welded lengthwise (6). In Fig. 3, a tubular film 7 was used instead of the plastic film. In both variants, plastic discs or foils 8 are placed on the front side and through Bonding or welding 6 connected to the plastic film 5 or the tube 7, so that the container 1 is hermetically sealed.

4 shows an embodiment of the active mass container 1 with an ignition transfer layer 9, which is integrated at least between the inner wall of the container 1 and the active body 2 or the flares 3, 4 and optimizes the ignition or activation of the active body 2. The intermediate layer (6) may consist of NC and / or RP granules.

The activation of the active body 2 itself can be done by laser entry, thermal, inductive etc.
