Description

BESCHREIBUNG DESCRIPTION

Wirkkörper für eine Submunition mit WirkmittelnActive body for a submunition with active agents

Die Erfindung betrifft eine thermische Isolierschicht zwischen insbesondere Nebel- Leucht- Behältern.The invention relates to a thermal insulating layer between in particular fog light containers.

Infrarot -, radar- als auch Dual Mode- gelenkte Flugkörper werden u. a. zur Bekämpfung beispielsweise von Seezielen, wie Schiffen, oder anderen Objekten zu Land und Luft eingesetzt. Nach Abschuss fliegen diese Flugkörper bzw. Raketen anfänglich inertialgestützt (z. B. DE 196 01 165 A1) oder GPS gelenkt in das Zielgebiet. Der Flugkörper geht danach in eine Suchphase (search- Phase) über, wenn er sich dem Ziel entsprechend angenähert hat. Als weiteres schalten sich die Flugkörper auf das Ziel auf (lock-on) und verfolgen dieses bis zum Einschlag (track -Phase). Eine „Track- gate" Tiefe D beträgt bei älteren Flugkörpern ca. 150 m, bei modernen nur wenige Meter.Infrared, radar and dual mode guided missiles may become a. used for example to combat sea targets, such as ships, or other objects on land and air. After launch, these missiles or rockets initially fly inertially (eg DE 196 01 165 A1) or GPS steered into the target area. The missile then goes into a search phase (search phase) when it has approached the target accordingly. In addition, the missiles turn on the target (lock-on) and follow this until the impact (track phase). A "track gate" depth D is about 150 m for older missiles, and only a few meters for modern aircraft.

Zur Täuschung derart gelenkter Flugkörper werden unterschiedliche Täuschkörper eingesetzt, um zum Schutz von Objekten die Flugkörper durch Störung in / an ihrer Funktion zu hindern. Einige Täuschkörper senden bei Erkennung einer Bedrohung elektromagnetische Täuschsignale (DE 100 16 781 C2) aus, andere bauen „Wolken" von schwebenden Dipolen (Chaff -Wolken) auf, welche auf die Radarfrequenz des Flugkörpers abgestimmt sind.To deceive such guided missile different decoys are used to prevent the protection of objects missiles by disturbance in / at their function. Some decoys emit electromagnetic noise signals (DE 100 16 781 C2) upon detection of a threat, others build up "clouds" of floating dipoles (chaff clouds), which are tuned to the radar frequency of the missile.

Pyrotechnische Gegenstände werden als Submunition aus einem Projektil bei einer bestimmten Flughöhe ausgestoßen und dabei angezündet, wobei sie brennend auf den Boden fallen.Pyrotechnic articles are ejected as submunitions from a projectile at a certain altitude and thereby ignited, falling to the ground burning.

Herkömmliche Submunitionen weisen jedoch gelegentlich den Nachteil auf, dass durch die Aufheizung ein unkontrollierbares Ablösen der Wirkmasse vom Wirkmassenbehälter erfolgen kann, was zu einer unkontrollierten Teilnahme an der exothermen Reaktion der Wirkmasse im System führen könnte. Bisher wurde eine höhere Festigkeit des Wirkmassenverbundes durch höhere Verpresskräf- te bei der Fertigung angestrebt.However, conventional submunitions occasionally have the disadvantage that the heating can cause an uncontrollable detachment of the active mass from the active mass container, which could lead to an uncontrolled participation in the exothermic reaction of the active material in the system. So far, a higher strength of the active mass composite was sought by higher Verpresskräf- te in the production.

Aus der EP 1 026 473 ist ein Verfahren zum Bereitstellen eines Scheinzieles zum Schutz von Land-, Luft- oder Wasserfahrzeugen oder dergleichen bekannt, bei welchem die Flugkörper, die einen im Infrator- oder Radar - Bereich oder einen in beiden Wellenlängenbereichen gleichzeitig oder seriell operierenden Zielsuchkopf aufweisen. Insbesondere die RF- Wirkmasse in Form von Dipolpaketen ist dabei durch ein Hitzeschild vor der Ausblashitze geschützt.From EP 1 026 473 a method for providing a decoy target for the protection of land, air or water vehicles or the like is known, in which the missiles, one simultaneously or serially operating in the infrared or radar range or in both wavelength ranges Have homing head. In particular, the RF active material in the form of dipole packages is protected by a heat shield in front of the Ausblashitze.

Hier stellt sich die Erfindung die Aufgabe, die vorgenannten Nachteile vermeidend eine Submunition mit Wirkmassen aufzuzeigen, die in der Funktionssicherheit der Wirkmassen bedeutend verbessert ist.Here, the invention has the object of avoiding the aforementioned disadvantages, a submunition with effective masses, which is significantly improved in the reliability of the active compositions.

Der Erfindung liegt die Idee zugrunde, durch Einbindung einer insbesondere thermischen Isolierschicht zwischen den Submunitionen die durch den gezielten Abbrand der Wirkmassen entstehenden Wärmeentwicklung und den dann folgenden Wärmedurchgang über den Wirkmassenbehälter auf darunter liegenden Wirkmassenschichten zu verhindern. Die Isolierschicht wird durch Einpressen, Einlegen, Einspritzen und/ oder Auftragen in / auf den Wirkmassenbehälter gebracht, danach erfolgt die anschließende Wirkmassenbefüllung. Dadurch wird während des Abbrands sichergestellt, dass ein minimierter Wärmeeintrag in die noch unverbrannte Wirkmasse infolge von Wärmedurchgang erfolgt. Eine Überzündung und explosionsartige Verbrennung wird verhindert. Die Trennung der Wirkmasse vom Behälter verhindert, dass beim Abbrand ein Wärmeeintrag / Reaktion vom Behälter auf die Wirkmasse stattfindet.The invention is based on the idea, by incorporating a particular thermal insulating layer between the submunitions to prevent the heat generated by the targeted burning of the active compositions and the subsequent heat transfer through the active mass container on underlying layers of active material. The insulating layer is brought by pressing, inserting, injecting and / or application in / on the active mass container, then the subsequent active mass filling takes place. As a result, it is ensured during the burnup that a minimized heat input into the still unburned active mass takes place as a result of heat transfer. Over-ignition and explosive combustion is prevented. The separation of the active material from the container prevents the burning takes place a heat input / reaction from the container to the active mass.

Ein damit verbundener Vorteil ist, dass diese Schicht eine stoßdämpfende Wirkung besitzt und dazu geeignet ist, den beim Bodenaufschlag entstehenden Kraft / Impulseintrag auf die Wirkmasse zu minimieren. Gleichzeitig verhindert die Isolierschicht das Herausfallen der Wirkmasse aufgrund von Festigkeitsverlusten insbesondere bedingt durch die Wärmeentwicklung.An associated advantage is that this layer has a shock-absorbing effect and is suitable for minimizing the force / momentum effect created on the ground impact on the effective mass. At the same time, the insulating layer prevents falling out of the active mass due to strength losses, in particular due to the evolution of heat.

Als Basis für die Isolierschicht kommen bevorzugt Zubereitungen oder Erzeugnisse von nichttoxischen, organischen oder anorganischen Verbindungen der Gruppen 2, 3, sowie 4 des Periodensystems der Elemente wie zum Beispiel Magnesium, Calcium, Bor, Aluminium, Kohlenstoff, Silizium sowie Zinn zum Einsatz, also Verbindungen, die durch ihre chemischen und physikalischen Eigenschaften die charakteristischen Voraussetzungen einer Isolierschicht erfüllen.As a basis for the insulating layer are preferably used preparations or products of non-toxic, organic or inorganic compounds of groups 2, 3, and 4 of the Periodic Table of the Elements such as magnesium, calcium, boron, aluminum, carbon, silicon and tin, so compounds by their chemical and physical properties meet the characteristic requirements of an insulating layer.

Durch Einbindung einer Isolierschicht wird somit die Funktionssicherheit durch das Einleiten eines gleichmäßigen Abbrands der Wirkmasse bis Brennschluss und damit verbunden die Verbesserung einer gleichmäßigeren Funktion durch die Wirkkörper als auch die Sicherheit gegen Wurfstücke bei explosivem Abbrand erhöht.By incorporating an insulating layer thus the reliability is increased by initiating a uniform burnup of the active mass until burnout and thus the improvement of a more uniform function by the active body as well as the security against throwing pieces in explosive burnup.

Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Es zeigt die einzige Figur den Prinzipaufbau eines pyrotechnischen Nebelkörpers 1 mit einer Isolierschicht 2 zwischen Wirkkörperbehälter 3 und dem pyrotechnischen Satz 4. Die Wirkkörperbehälter 3 sind symmetrisch um eine imaginäre Geschosslängsachse 10 verteilt. Mehrere Wirkkörperbehälter 3 können eine zu verschießende Submunition bilden (nicht näher dargestellt). Verschlossen werden kann der Behälter 3 bzw. das Gehäuse mit einem Deckel 5 mit Ausblasöffnung 6. Reference to an embodiment with drawing, the invention will be explained in more detail. The sole figure shows the basic structure of a pyrotechnic smoke body 1 with an insulating layer 2 between the active body container 3 and the pyrotechnic composition 4. The active body container 3 are distributed symmetrically about an imaginary projectile longitudinal axis 10. Several active body containers 3 can form a submunition to be fired (not shown in detail). Can be closed, the container 3 or the housing with a cover 5 with exhaust opening. 6
