- IR infrared
- RF radar
- a threat from modern, autonomously operating missiles will increase significantly because even missiles with the latest homing systems due to the collapse of the former Great power of the Soviet Union and generous export regulations, especially Asian ones States find widespread use.
- the target search systems of such missiles mainly work in the radar range (RF) and in the infrared range (IR). Both the radar backscattering behavior as well as the radiation of specific infrared radiation from targets, e.g. ships Airplanes, tanks etc., used for target finding and target tracking.
- targets e.g. ships Airplanes, tanks etc.
- Multispectral IR homing heads work with two detectors that are sensitive in the short- and long-wave infrared range to differentiate between false targets.
- So-called Dual mode homing heads work in the radar and infrared range. Missiles with such Target search heads are radar-controlled in the approach and search phase and switch in the tracking phase to an IR seeker head or switch it to it.
- a target criterion of dual mode target seekers is the co-location of the RF backscatter and the IR radiation center of gravity. Due to the possible target coordinate comparison wrong targets (e.g. clutter, like old-fashioned decoys) can be better discarded.
- the RFund co-location IR effectiveness is therefore a mandatory requirement for a dual mode decoy, to effectively deceive modern dual mode homing heads, i.e. of a to direct the object to be protected to an apparent target. Only the smallest possible Resolution cell of the target seeker (RF and IR) relevant for the co-location.

- the bottom cover 3 is preferably made of metal.
- a version made of glass or carbon fiber reinforced plastic is also possible.
- the outer launching body forms a housing sleeve 4, which is preferably consists of pure aluminum with an aluminum content of more than 99%.
- the housing sleeve 4 remains in the magazine.
- a bottom ring 5 creates a distance from a pressure chamber 6.
- the Pressure chamber 6 receives the propellant gas which is emitted when a propellant charge 8 burns off of the decoy floor is created.
- the propellant charge 8 is ignited by means of a squib 7 and preferably consists of a powder driving set, preferably black powder or black powder-like propellants such as nitrocellulose powder.
- An ignition retarder 11 is used for Definition of the route until an IR active mass 19 and an RF active mass 21 are emitted.
- the ignition retarder 11 is pyrotechnic and has a burn-through time of 2 seconds. Such ignition retarders are commercially available. The use is also conceivable a freely programmable electronic ignition retarder for variable setting the flight duration.

- the ignition delay 15 comprises a pyrotechnic Delay piece that ignites an ignition / disassembly kit 18 when the dispensing part 14 has left the projectile sleeve.
- the ignition delay 15 has a burning time of approximately 0.1 seconds.
- the blow-out pipe 16 serves as a receiver for the ignition / dismantling kit 18 and for control purposes the blowing speed. The blow-out speed depends on the length of the blow-out pipe 16 and the ratio of the total cross section of blow-out openings 17 to Amount of ignition / dismantling kit 18.
- the ratio is preferred chosen so that a blow-out time of 0.1 seconds is achieved.
- the blow pipe 16 must be manufactured in such a way that there is as little plastic deformation as possible during the blowing process entry.
- the exhaust pipe 16 was made of steel.
- the exhaust openings 17 must be attached in such a way that an even distribution of the RF and IR active masses 19 and 21 is reached. This is preferably achieved in such a way that one Blow-out opening 17 meets a position of the RF active mass 21.
- the ignition / disassembly kit 18 includes a pyrotechnic phrase that burns a comparable amount of gas supplies. Magnesium barium nitrate or aluminum perchlorate are preferably used for this purpose. The amount of the ignition / disassembly kit 18 depends on the blow-out pipe 16.
- the IR active mass 19 contains the IR active mass known from German patent DE-PS 43 27 976 MWIR flares. In principle, however, all IR active masses that can be used can be used Have the ignition charge activated. In the embodiment, disc-shaped MWIR flares used with 1/3 division. A cutting disc 20 protects the RF active mass 21 from burning MWIR flares of the IR active mass 19.

- the output of the active masses before Activation and distribution as well as the appropriate "packaging" of the dipoles 30 serves to clump together and to avoid fusion and a distance from dipole to dipole of about 7 to 10 ⁇ and thus to generate a high radar backscatter cross section.
- the packaging must always be be flexible enough to release the dipoles 30 independently and without external influence protect them from the effects of heat from the ignition and blow-out charge.
- the Packaging of the dipoles matched to the distribution principle, i.e. the packaged dipoles are 30 arranged so that they open immediately when blowing out.
- the slipping of the dipoles 30 is preferably Capton® or Milinex® used.
- Intermediate foils 32 can also be used aluminum foils of different thicknesses.
- a thin aluminum cover 33 which can also be a paper or cardboard cover that the RF active mass 21 not distributed immediately after ejection from the projectile sleeve, but remains together for as long as until the igniter charge 18 burns. This ensures that the Total energy of the charge can act on the RF active mass 21.
- a lid 23 is used for Completion of a projectile sleeve 22 and fixes the blow pipe 16 from above.
- the cover 23 can be made heavy metals such as Cast iron, or brass, are made to be the focus of the Move the decoy body as far forward as possible. This can stabilize the Flight can be achieved.

von Land-, Luft- oder Wasserfahrzeugen oder dergleichen vor Flugkörpern, die einen im Infrarot
(IR)- oder Radar (RF)-Bereich oder einen in beiden Wellenlängenbereichen gleichzeitig oder seriell
operierenden Zielsuchkopf aufweisen, nach dem Oberbegriff von Anspruch 1.The present invention relates to a method for providing a dummy target for protection

Eine Bedrohung durch moderne, autonom operierende Flugkörper wird deutlich zunehmen, da selbst Flugkörper mit modernsten Zielsuchsystemen durch den Zusammenbruch der ehemaligen Großmacht Sowjetunion sowie durch großzügige Exportbestimmungen insbesondere asiatischer Staaten große Verbreitung finden. Die Zielsuchsysteme derartiger Flugkörper arbeiten hauptsächlich im Radarbereich (RF) und im Infrarotbereich (IR). Dabei werden sowohl das Radarrückstreuverhalten sowie die Abstrahlung spezifischer Infrarotstrahlung von Zielen, wie z.B. Schiffen, Flugzeugen, Panzern etc., zur Zielfindung und Zielverfolgung genutzt. Bei modernsten Flugkörpern geht die Entwicklung eindeutig in Richtung multispektraler Zielsuchsysteme, die gleichzeitig oder auch seriell im Radar- und Infrarotbereich arbeiten, um eine verbesserte Falschzielunterscheidung durchführen zu können. Multispektrale IR-Zielsuchköpfe arbeiten mit zwei Detektoren, die im kurz- und langwelligen Infrarotbereich empfindlich sind, zur Falschzielunterscheidung. Sogenannte Dual Mode-Zielsuchköpfe arbeiten im Radar- und Infrarotbereich. Flugkörper mit derartigen Zielsuchköpfen werden in der Anflug- und Suchphase radargesteuert und schalten in der Verfolgungsphase auf einen IR-Suchkopf um oder schalten ihn dazu. Ein Zielkriterium von Dual Mode-Zielsuchköpfen ist die Co-Location der RF-Rückstreuung und des IR-Strahlungsschwerpunktes. Durch den möglichen Zielkoordinatenvergleich können Falschziele (z.B. Clutter, wie Täuschkörper alter Art) besser ausgesondert werden. Die Co-Location von RFund IR-Wirksamkeit ist demnach eine zwingende Voraussetzung für einen Dual Mode-Täuschkörper, um moderne Dual Mode-Zielsuchköpfe wirksam täuschen zu können, d.h. von einem zu schützenden Objekt auf ein Scheinziel zu lenken. Dabei ist lediglich die kleinstmögliche Auflösungszelle des Zielsuchkopfes (RF und IR) für die Co-Location relevant.A threat from modern, autonomously operating missiles will increase significantly because even missiles with the latest homing systems due to the collapse of the former Great power of the Soviet Union and generous export regulations, especially Asian ones States find widespread use. The target search systems of such missiles mainly work in the radar range (RF) and in the infrared range (IR). Both the radar backscattering behavior as well as the radiation of specific infrared radiation from targets, e.g. ships Airplanes, tanks etc., used for target finding and target tracking. With the most modern missiles The development clearly goes in the direction of multispectral homing systems that simultaneously or also work serially in the radar and infrared range in order to improve wrong target differentiation to be able to perform. Multispectral IR homing heads work with two detectors that are sensitive in the short- and long-wave infrared range to differentiate between false targets.

Auch wird erfindungsgemäß vorgeschlagen, daß Dipolpakete verwendet werden, die derart angeordnet sind, daß sie sich beim Ausblasen unmittelbar öffnen.It is also proposed according to the invention that dipole packets are used which are arranged in this way are that they open immediately when blowing out.
Ferner wird erfindungsgemäß vorgeschlagen, daß Dipolpakete verwendet werden, die zum Schutz vor einem Ineinanderrutschen durch jeweils mindestens eine hitzebeständige Folie voneinander getrennt werden.It is also proposed according to the invention that dipole packets are used for protection before slipping into each other by at least one heat-resistant film be separated.
Auch wird erfindungsgemäß vorgeschlagen, daß zum Anzünden und Ausblasen eine pyrotechnische Ladung verwendet wird, die durch einen Anzündverzögerer gezündet wird, der durch den Ausbrand einer Treibladung für das Täuschkörpergeschoß gezündet wird. It is also proposed according to the invention that a pyrotechnic for lighting and blowing out Charge is used, which is ignited by an ignition retarder, which by the Burnout of a propellant charge for the decoy shell is ignited.
Außerdem wird vorgeschlagen, daß die pyrotechnische Ladung der Anzünd- und Ausblaseinheit innerhalb eines mittig in dem Geschoß angeordneten Rohres mit definierten Ausblasöffnungen abgebrannt wird.It is also proposed that the pyrotechnic charge of the ignition and blow-out unit within a pipe arranged centrally in the floor with defined blow-out openings is burned down.
Ferner wird erfindungsgemäß vorgeschlagen, daß eine RF-Wirkmasse verwendet wird, die auf ihrer Mittelfläche von einer Papier-, Papp- oder Kunststofffolienhülle umgeben ist.It is further proposed according to the invention that an RF active mass is used which is based on its middle surface is surrounded by a paper, cardboard or plastic film sleeve.
Dabei ist erfindungsgemäß vorgesehen, daß die Wirkmassen einschließlich der Aktivierungs- und Verteilungseinrichtung mittels eines Ausbringteils gemeinsam aus einer Geschoßhülse ausgestoßen werden.It is provided according to the invention that the active masses including the activation and Distribution device jointly ejected from a projectile sleeve by means of a delivery part become.
Auch wird vorgeschlagen, daß zum Ausstoßen des Ausbringteils eine Ausstoßtreibladung verwendet wird, die durch den Anzündverzögerer gezündet wird, der vorzugsweise pyrotechnisch ist.It is also proposed that an ejection propellant be used to eject the application part is ignited by the ignition retarder, which is preferably pyrotechnic.
Es ist erfindungsgemäß vorgesehen, daß die Wirkmassen in Flugrichtung hintereinander ringförmig um die Anzünd- und Ausblaseinheit angeordnet sind, die Anzünd- und Ausblaseinheit eine Anzünd- und Ausblasladung sowie Ausblasöffnungen umfaßt, und die Anzünd- und Ausblasladung in einer derartig auf die Anzahl und den Querschnitt der verwendeten Ausblasöffnungen abgestimmten Menge verwendet wird, daß keine großen Beschleunigungskräfte auf die Wirkmassen einwirken.It is provided according to the invention that the active masses are ring-shaped in succession in the direction of flight are arranged around the ignition and blow-out unit, the ignition and blow-out unit Ignition and blowout charge and blowout openings includes, and the ignition and blowout charge in such a way matched to the number and cross section of the blow-out openings used Quantity is used that no large acceleration forces on the active masses act.
Außerdem wird erfindungsgemäß vorgeschlagen, daß ein Geschoß mit einem Kaliber im Bereich on etwa 10 bis 155 mm verwendet wird.In addition, the invention proposes that a projectile with a caliber in the range about 10 to 155 mm is used.
Auch wird erfindungsgemäß vorgeschlagen, daß eine IR-Wirkmasse mit Flares mit mittelwelligem Strahlungsanteil (MWIR-Flares) verwendet wird. It is also proposed according to the invention that an IR active mass with flares with a medium wave Radiation component (MWIR flares) is used.

Fig. 1 dient zur Veranschaulichung des prinzipiellen Verfahrensablaufes gemäß einer besonderen Ausrührungsform der Erfindung. Das erfindungsgemäße Verfahren läßt sich am besten an dem zeitlichen Verlauf von dem Abschuß eines nach dem erfindungsgemäßen Verfahren arbeitenden Täuschkörpers bis zur Verteilung der Wirkmassen darstellen. Der zeitliche Verlauf läßt sich grob in drei Phasen einteilen:
- Phase I
- Abschuß eines Täuschkörpers
- Phase II
- Ausstoß der IR- und RF-Wirkmasse und
- Phase III
- Aktivierung und Verteilung der Wirkmassen
- Phase I
- Firing a decoy
- Phase II
- Ejection of the IR and RF active mass and
- Phase III
- Activation and distribution of the active masses
Fig. 1 gibt die Phasen II bis III schematisch wieder. Die Zündung und der Abschuß gemäß Phase I geht entsprechend dem Stand der Technik vonstatten. In der Phase II werden die Wirkmassen einschließlich eines Aktivierungs- und Verteilungsmechanismus während des Fluges aus der Geschoßhülse des Tarnkörpers ausgestoßen, um eine nachfolgende Verteilung der Wirkmassen ohne Verdämmung zu erzielen, womit der Vorteil verbunden ist, daß bei der Verteilung der Wirkmassen kein überhöhter Druck auf die Wirkmassen einwirkt. Dies führt dazu, daß die Verteilung der IR-Wirkmasse, aber insbesondere die Verteilung der RF-Wirkmasse nachhaltig verbessert wird. In der Phase III wird eine effektive Wirkmassenverteilung durch ein zentrales Ausblasen erzielt.Fig. 1 shows the phases II to III schematically. Ignition and launch according to phase I proceeds according to the state of the art. In phase II, the active substances are included an activation and distribution mechanism in flight from the projectile casing the camouflage body ejected to a subsequent distribution of the active mass without To achieve insulation, which has the advantage that the distribution of the active masses no excessive pressure acts on the active masses. As a result, the distribution of the IR active mass, but in particular the distribution of the RF active mass is sustainably improved. In the In phase III an effective distribution of active mass is achieved by central blowing out.
Fig. 2 zeigt einen Längsschnitt durch einen Täuschkörper, der gemäß der in Fig. 1 skizzierten besonderen
Ausführungsform des erfindungsgemäßen Verfahrens arbeitet. Mit 1 ist ein kompletter
Sekundärteil zur induktiven Zündenergieaufnahme von einem Primärteil gekennzeichnet. Der Sekundärteil
1 besteht aus magnetischem Material, vorzugsweise Eisen. In einer Sekundärspule 2
wird die Zündenergie induziert. Die Wicklungen der Sekundärspule 2 bestehen aus mit Isolierlack
behandeltem Kupferdraht. Die Anzahl der Wicklungen entspricht vorzugsweise derjenigen einer
Primärspule, wobei aber eine Transformation prinzipiell möglich ist. Ein vorzugsweise aufgebördelter
Bodendeckel 3 dient als unterer Sicherungsabschluß des Täuschkörpers. Der Bodendeckel 3
besteht vorzugsweise aus Metall. Eine Ausführung aus glas- oder kohlefaserverstärktem Kunststoff
ist aber auch möglich. Den äußeren Abschußkörper bildet eine Gehäusehülse 4, die vorzugsweise
aus Reinaluminium mit einem Aluminiumanteil von mehr als 99% besteht. Die Gehäusehülse
4 verbleibt im Magazin. Ein Bodenring 5 stellt eine Distanz zu einer Druckkammer 6 her. Die
Druckkammer 6 nimmt das Treibgas auf, das bei einem Abbrand einer Treibladung 8 zum Ausstoßen
des Täuschkörpergeschosses entsteht. Die Treibladung 8 wird mittels einer Zündpille 7 gezündet
und besteht vorzugsweise aus einem Pulvertreibsatz, vorzugsweise Schwarzpulver oder
schwarzpulverähnliche Treibsätze wie Nitrocellulosepulver. Ein Anzündverzögerer 11 dient zur
Festlegung der Flugstrecke bis zum Ausstoß einer IR-Wirkmasse 19 und einer RF-Wirkmasse 21.
Der Anzündverzögerer 11 ist pyrotechnisch ausgeführt und hat eine Durchbranddauer von 2 Sekunden.
Derartige Anzündverzögerer sind im Handel erhältlich. Denkbar ist aber auch die Verwendung
eines frei programmierbaren elektronischen Anzündverzögerers zur variablen Festlegung
der Flugdauer. Ein Verbindungsteil 12 enthält den Anzündverzögerer 11 und eine Ausstoßtreibladung
13 zum Ausstoß eines Ausbringteiles 14. Das Verbindungsteil 12 ist vorzugsweise aus Metall
gefertigt. Die Ausstoßtreibladung 13 umfaßt einen Pulvertreibsatz, vorzugsweise Schwarzpulver
oder schwarzpulverähnliche Treibsätze wie Nitrocellulose. Das Ausbringteil 14 dient als
Treibspiegel für die Ausstoßtreibladung 13 und ist derart ausgeführt, daß es als Halterung für einen
Anzündverzögerer 15 und für ein Ausblasrohr 16 dient. Das Ausbringteil 14 ist vorzugsweise aus
einem Aluminiumguß- oder Frästeil gefertigt. Der Anzündverzögerer 15 umfaßt ein pyrotechnisches
Verzögerungsstück, das einen Anzünd-/Zerlegersatz 18 zündet, wenn das Ausbringteil 14
die Geschoßhülse verlassen hat. Der Anzündverzögerer 15 hat eine Brenndauer von ca. 0,1 Sekunden.
Das Ausblasrohr 16 dient als Aufnehmer für den Anzünd-/Zerlegersatz 18 und zur Steuerung
der Ausblasgeschwindigkeit. Die Ausblasgeschwindigkeit ist abhängig von der Länge des Ausblasrohres
16 und von dem Verhältnis des Gesamtquerschnittes von Ausblasöffnungen 17 zur
Menge des Anzünd-/Zerlegersatzes 18. Allgemein läßt sich sagen, daß, je höher die Menge des
Anzünd-/Zerlegersatzes 18 und je kleiner der Gesamtquerschnitt der Ausblasöffnungen 17 ist, um
so größer die Ausblasgeschwindigkeit ist. In dem Ausführungsbeispiel ist das Verhältnis vorzugsweise
so gewählt, daß eine Ausblaszeit von 0,1 Sekunden erreicht wird. Das Ausblasrohr 16 muß
so gefertigt werden, daß möglichst keine plastische Verformung während des Ausblasvorgangs
eintritt. Bei dem Ausführungsbeispiel wurde das Ausblaßrohr 16 aus Stahl gefertigt. Die Ausblasöffnungen
17 müssen derart angebracht werden, daß eine gleichmäßige Verteilung der RF- und IR-Wirkmassen
19 und 21 erreicht wird. Dies wird vorzugsweise derart erreicht, daß jeweils eine
Ausblasöffnung 17 auf eine Lage der RF-Wirkmasse 21 trifft. Der Anzünd-/Zerlegersatz 18 umfaßt
einen pyrotechnischen Satz, der als Abbrandprodukt eine vergleichbar große Menge an Gas
liefert. Vorzugsweise werden hierzu Magnesium-Bariumnitrat oder Aluminium-Perchlorat verwendet.
Die Menge des Anzünd-/Zerlegersatzes 18 ist abhängig vom Ausblasrohr 16. Die IR-Wirkmasse
19 enthält die aus dem deutschen Patent DE-PS 43 27 976 bekannte IR-Wirkmasse mit
MWIR-Flares. Grundsätzlich sind jedoch alle IR-Wirkmassen verwendbar, die sich durch eine
Anzündladung aktivieren lassen. Bei dem Ausführungsbeispiel werden scheibenförmige MWIR-Flares
mit 1/3-Teilung verwendet. Eine Trennscheibe 20 schützt die RF-Wirkmasse 21 vor den
brennenden MWIR-Flares der IR-Wirkmasse 19. Die Trennscheibe 20 kann aus Metall oder vorzugsweise
aus feuerresistenter Folie gefertigt sein. Die Ausführung der RF-Wirkmasse 21 ist ausführlicher
in Fig. 3 dargestellt. Als RF-Wirkmasse 21 werden aus Hitzeschutzgründen zusammengerollte
Radar-Düppel mit Dipolen 30 aus Aluminium- oder Silber-beschichteten Glasfaserfäden
mit einer Dicke im Bereich von etwa 10 bis 100 µm verwendet. Die Dipollänge beträgt 17,9 mm.
Es sind aber auch Dipollängen ab ca. 1 mm bis ca. 25 mm möglich und vorgesehen. Die Anzahl
der Umwicklungen der einzelnen Dipol-Pakete (Chaff-Pakete) ist variabel von 1 aufwärts. Vorzugsweise
werden für die Pakete 1,5 Wicklungen verwendet. Der Ausstoß der Wirkmassen vor der
Aktivierung und Verteilung sowie die geeignete "Verpackung" der Dipole 30 dient dazu, ein Verklumpen
und Verschmelzen zu vermeiden und einen Abstand von Dipol zu Dipol von etwa 7 bis
10 λ und somit einen hohen Radarrückstreuquerschnitt zu erzeugen. Die Verpackung muß grundsätzlich
flexibel genug sein, die Dipole 30 ohne äußere Einwirkung selbständig freizugeben und
sie vor der Hitzeeinwirkung durch die Anzünd- und Ausblasladung zu schützen. Zudem ist die
Verpackung der Dipole auf das Verteilungsprinzip abgestimmt, d.h. die verpackten Dipole 30 sind
so angeordnet, daß sie sich beim Ausblasen unmittelbar öffnen. Als Material für die Wicklungen
und für durch die ganze RF-Wirkmasse durchgehende Schutzfolien 31 und Schutzfolien 32 gegen
das Ineinanderrutschen der Dipole 30 wird vorzugsweise Capton® oder Milinex® verwendet. Als
Zwischenfolien 32 können auch Aluminiumfolien verschiedener Stärke verwendet werden. Eine
dünne Aluminiumhülle 33, die aber auch eine Papier- oder Papphülle sein kann, daß sich die RF-Wirkmasse
21 nach dem Ausstoß aus der Geschoßhülse nicht sofort verteilt, sondern solange zusammenbleibt,
bis die Anzünd-/Zerlegerladung 18 abbrennt. Dadurch wird gewährleistet, daß die
Gesamtenergie der Ladung auf die RF-Wirkmasse 21 einwirken kann. Ein Deckel 23 dient zum
Abschluß einer Geschoßhülse 22 und fixiert von oben das Ausblasrohr 16. Der Deckel 23 kann aus
schweren Metallen, wie z.B. Gußeisen oder Messing, gefertigt werden, um den Schwerpunkt des
Täuschkörpers möglichst weit nach vorne zu verschieben. Dadurch kann eine Stabilisierung des
Fluges erreicht werden. Der Deckel 23 wird durch einen Dichtring 24 zu der Geschoßhülse 22 abgedichtet,
die vorzugsweise aus Aluminium mit einem Reinheitsgrad von über 99% gezogen ist.
25 stellt ein Verschlußstück des Ausblasrohres 16 dar und gewährleistet, daß die relativ gefährliche
Zerlegerladung als letzter Arbeitsgang in den Täuschkörper eingeführt werden kann.Fig. 2 shows a longitudinal section through a decoy, which according to the particular sketched in Fig. 1
Embodiment of the method according to the invention works. With 1 is a complete
Secondary part for inductive ignition energy absorption characterized by a primary part. The
In Fig. 4 ist eine weitere Ausführungsform eines Täuschkörpers gezeigt, der gemäß einer besonderen
Ausführungsform des Verfahrens funktioniert. In Fig. 4 sind dieselben Bezugszeichen wie in
Fig. 2 benutzt. Im folgenden soll i.w. nur auf die Unterschiede zu dem Täuschkörper gemäß Fig. 2
eingegangen werden. Ein wesentlicher Unterschied besteht darin, daß das Geschoß keine Geschoßhülse
(in Fig. 2 mit Bezugszeichen 22 gekennzeichnet) aufweist. Somit müssen die IR-Wirkmasse
19 und RF-Wirkmasse 21 vor ihrer Aktivierung und Verteilung nicht aus einer Geschoßhülse
ausgestoßen werden und sind somit die Ausstoßtreibladung (mit Bezugszeichen 13 in
Fig. 2 gekennzeichnet) für das Ausbringteil 14 sowie der Anzündverzögerer (mit Bezugszeichen
15 in Fig. 2 gekennzeichnet) nicht mehr notwendig und daher nicht vorhanden. Das Ausbringteil
14 dient auch nicht mehr zum Ausstoßen der Wirkmassen 19, 21 aus einer Geschoßhülse. Die RF-Wirkmasse
21 ist von einer Papier- bzw. Papphülle 33a anstelle einer Aluminiumhülle (Bezugszeichen
33 in Fig. 3) umgeben. Diese Papier- bzw. Papphülle 33a reicht zusammen mit dem zentralen
Ausblasrohr 16 aus, die RF-Wirkmasse 21 trotz der Luftanströmung in der Flugphase vor
der eigentlichen Aktivierung und Verteilung zusammenzuhalten. Ein Sicherungselement 34 sorgt
für Vorrohrsicherheit. Der in Fig. 4 gezeigte Täuschkörper weist aufgrund der fehlenden Geschoßhülse
den Vorteil auf, daß er im Verhältnis zu einem Täuschkörper mit Geschoßhülse einfacher
herzustellen und wesentlich billiger ist.4 shows a further embodiment of a decoy body, which according to a special
Embodiment of the method works. 4 are the same reference numerals as in
Fig. 2 used. In the following, i.w. only on the differences to the decoy according to FIG. 2
To be received. An essential difference is that the projectile is not a projectile sleeve
