Abstract
The invention relates to a submunition having effective masses, particularly having at least one pyrotechnic fog body (1), comprising an insulation layer (2) between an active body container (3) and a pyrotechnic unit (4), wherein the active body container (3) can be closed by a cover (5) having a blow-out opening (6).
Description
DESCRIPTION
Active body for a submunition having effective agents The invention relates to a thermal insulating layer in particular between smoke and flare containers.
Infrared-guided, radar-guided and dual-mode-guided missiles are used, inter alia, to attack, for example, seaborne targets, such as marine vessels, or other objects on the land and in the air. After being fired, these missiles or rockets initially fly with inertial assistance (for example DE 196 01 165 Al) or are guided by GPS to the target region. The missile then enters a search phase once it is sufficiently close to the target. Furthermore, the missiles are switched to the target (lock-on) and track this target until impact (track phase) . A "track-gate" depth D is approximately 150 meters in relatively old missiles, and only a few meters in modern missiles.
Various decoy bodies are used to decoy such guided missiles, in order to impede the function of the missiles by jamming or interference, in order to protect objects. When a threat is identified, some decoy bodies emit electromagnetic decoy signals (DE 100 16 781 C2), and others form "clouds" of floating dipoles (chaff clouds), which are matched to the radar frequency of the missile.
Pyrotechnic objects are ejected as submunition from a projectile at a specific altitude and are initiated in the process, before they then fall to the ground as they burn.
However, conventional submunitions occasionally have the disadvantage that heating can result in uncontrollable separation of the active mass from the active mass container, which could lead to uncontrolled involvement in the exothermic reaction of the active mass in the system.
Until now, the aim of achieving an active mass assembly of greater strength has been attempted by greater compression forces during manufacture.
EP 1 026 473 discloses a method for providing a decoy target for protection of land vehicles, aircraft or watercraft or the like, in which the missiles have a target seeker head which operates in the infrared band or radar band, or a target seeker head which operates in both wavelength bands at the same time or successively. In this case, the RF active mass in the form of dipole packs, in particular, is protected by a heat shield against the blow-out heat.
The object of the invention here is to specify a submunition with active masses which avoids the abovementioned disadvantages and in which the functional reliability of the active masses is considerably improved.
The invention is based on the idea of including an insulating layer, in particular a thermal insulating layer, between the submunitions to prevent the heat development that results from deliberate combustion of the active masses and the heat transfer which then follows via the active mass container to active mass layers located underneath. The insulating layer is fitted in/on the active mass container by pushing in, insertion, injection and/or application, after which filling with the active mass takes place. This ensures that a minimum amount of heat is introduced into the active mass that has not yet been burnt, as a result of the heat transfer during combustion. Flashover and explosive combustion are prevented. The separation of the active mass from the container prevents heat being introduced from the container to the active mass, and/or a reaction from the container on the active mass, during combustion.
One advantage associated with this is that this layer has a shock-absorbing effect and is therefore suitable for minimizing the force/impulse introduced to the active mass as a result of striking the ground. At the same time, the insulating layer prevents the active mass from falling out as a result of strength losses, in particular resulting from heat development.
Preparations or products of non-toxic, organic or inorganic compounds from groups 2, 3 and 4 of the periodic table of the elements, such as magnesium, calcium, boron, aluminum, carbon, silicon and tin, are preferably used, that is to say compounds whose chemical and physical characteristics comply with the characteristic preconditions of an insulating layer are used, as the basis for the insulating layer.
The inclusion of an insulating layer therefore improves the functional reliability by initiation of uniform combustion of the active mass until completion of burning, and, associated with this, improves a more uniform function by the active bodies, as well as improving safety with regard to objects thrown out during explosive combustion.
The invention will be explained in more detail with reference to one exemplary embodiment and a drawing.
The single figure shows the basic design of a pyrotechnic smoke body 1 having an insulating layer 2 between the active body container 3 and the pyrotechnic charge 4. The active body containers 3 are distributed symmetrically around an imaginary projectile longitudinal axis 10. A plurality of active body containers 3 can form a submunition to be fired (not illustrated in any more detail). The container 3 or the housing can be closed by a cover 5 with a blow-out opening 6.
