Definitions
- the invention is concerned with an encapsulated active body without its own ignition or ignition chain for an infrared decoy.
- An active body with ignition chain or ignition is briefly described for example in DE 199 51 767 C2. This fulfills the task of a dual-mode decoys.
- the active substance emitting radiation in the IR range is formed here from a plurality of flares.
- a camouflage and deception ammunition of this type for the protection of objects against missiles containing the active substances forming fog and / or dummy targets is furthermore dealt with in DE 10 2005 020 159 B4.
- Known IR active bodies consist of a particular cylindrical body which is formed by stacking individual active body leaves (flare leaflets or discs). The resulting package is held together by a foil or other compound, such as plastic cord, etc.
- the film itself serves to protect the active body against environmental influences and storage, transport and in the dispenser itself.
- a new ignition concept in particular for the formation of decoy clouds in civil aviation, etc. without ignition and explosives is described in more detail in DE 10 2006 004 912 A1. It is a system known to protect, in particular, large flying platforms, such as aircraft, from IR or radar-directed threats.
- the activation or ignition of the active body preferably takes place without contact.
- the ejection of the active body is then carried out pneumatically or mechanically.
- the active bodies themselves are ammunition-free packages which are ignited by means of hot air or a laser.
- the ignition behavior of the active body for the formation of the decoy target cloud represents even more optimization options.
- the invention therefore has the task of demonstrating an active body with optimized ignition behavior.
- the object is achieved by the features of claim 1.
- Advantageous embodiments are contained in the subclaims.
- the invention is based on the idea not to surround the active body with a film or the like, but this so capsules that the encapsulation, for example in the form of a shell, etc. supports the Anzünd the active mass or the components.
- the so-called encapsulated active body is characterized in that the IR active body is completely housed inside a stable, dense and preferably combustible shell.
- the active body itself consists of one or preferably a plurality of individual components which have different properties and / or chemical compositions.
- the individual components can u. a. with regard to ignition sensitivity, burning rate, burning time, power, etc.
- the ignition speed can be increased by additionally introducing a suitable ignition aid / mixture inside the shell.
- 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.
- 1 is a schematic diagram of an encapsulated active body
- Fig. 3 shows a further embodiment of the active body.
- 1 denotes a so-called encapsulated active body in a sectional view.
- the ignition aid 5 can be introduced as an additional component as a powder or granules in the combustible shell 2.
- the two individual components 3, 4 are preferably different in terms of their chemical composition and their properties. It is thus possible to combine materials of various properties, such as burn-up, ignitability, power, burning time, etc. By a suitable combination of the various individual components 3, 4, the effect of the decoy can be adapted to the respective requirements.
- the inner geometry of the shell 2 of the active body 1 is arbitrary.
- the mechanical stability and the protection against environmental influences, etc. are ensured by the shell 2.
- the combustible shell may be ignited by contact with a hot surface, by coupling laser radiation, inductive ignition, and other suitable methods such as friction.
- the combustible shell 2 is ignited by laser radiation, substances are advantageously added to the sleeve material which facilitate the transmission of the laser radiation and the ignition of the combustible shell 2. These should be such substances that have the lowest possible reflection zw. High absorption at the wavelength of the laser system used.
- the ignition of the combustible shell 2 or of the active body 1 takes place in a first variant from the outside over the upper side surface 10 of the active body 1.
- the ignition in another variant by a located inside the active body 1 prevailanzündmischung 6 by a L jossanzündung. 7 ( Figure 2).
- a combination of both variants is also possible.
- the described sandwich construction of the active body 1 can also take place in a kind of combination carrier, wherein the various components 3, 4 are not located next to each other inside the sleeve 2.
- the individual components 3, 4 could already be connected to one another during the production of the internal structure, in which, for example, one component 3, 4 forms the carrier material to which the other component (s) 4, 3 are applied.
