Definitions
- the invention relates to a submunition unit with a warhead, which, viewed in the direction of flight, on the bow side comprises an antenna for target determination and which is connected at the rear to a detachably mounted parachute cartridge.
- an antenna is understood to mean both a high-frequency antenna and an optical sensor for detecting targets.
- a submunition unit of the type mentioned above is known for example from the documents DE 39 24 352 C1 and DE 41 24 655 C2.
- this known submunition unit which is usually ejected from a carrier projectile over a predetermined target area, during the sinking phase of the submunition unit, the parachute cartridge containing a rotation parachute is detached from the warhead.
- the rotation parachute connected to the warhead unfolds, and the warhead begins to rotate over the target area during the sinking process, so that the antenna arranged at the warhead on the bow side scans the target area.
- the warhead charge e.g., a projectile-forming charge
- the antenna arranged in the warhead is a relatively fragile structural unit, it must be protected against both mechanical stresses acting on the submunition unit located in the support shell and against aerodynamic stresses arising after the ejection of the submunition unit Support projectile act on the warhead.
- the invention is therefore based on the object to provide a Submunitionshow of the type mentioned above, the antenna by a simple protection device both is adequately protected against mechanical loads as well as against aerodynamic stresses, without this adversely affecting the operation of the antenna.
- the invention is based essentially on the idea that for protecting the antenna in front of an antenna protective cover is detachably attached to the warhead, and that the warhead comprises a mechanism of action, which causes a release of the antenna protective cover upon release of the parachute from the warhead.
- the antenna protection cover is at least two, but preferably three, evenly distributed over the circumference of the antenna protection cover arranged prestressed elastic bands, possibly also Spangenaus spring steel, positively connected to the parachute or the warhead, such that when detaching the parachute from the warhead the parachute cassette ends of the tension straps are free and the antenna protection cover is controlled by the axial delay of parallel in time at the warhead tail unfolding parachute (parachute stretch) separated.
- Such an arrangement of the antenna protection cover on the warhead has, inter alia, the advantage that no additional pyrotechnic energy sources, etc. are required for shedding the antenna protection cover and the mechanism of action is therefore extremely reliable without influencing peripheral components of the submunition and higher-level functional processes.
- the elastic tension bands may preferably extend along the outside of the warhead between the antenna protection cover and the parachute cartridge. It has proved to be advantageous if the parachute cartridge side ends of the tension straps are designed as spring clips, which engage in the outer wall of the antenna protection cover arranged tab-shaped projections behind (snap mechanism).
- FIG. 1 shows a perspective view of a submunition unit according to the invention with a warhead and an antenna protection cover attached to the front side thereof,
- FIG. 2 shows a perspective view of the submunition unit corresponding to FIG. 1, wherein the antenna protection cover has been released.
- 1 denotes a submunition unit according to the invention which can be moved over a target area with a carrier projectile (not shown).
- the submunition unit 1 comprises a warhead 2, on the bow side of which an antenna 3 (for example a millimeter wave antenna) and on the rear side a parachute cassette 4 (for example for a parachute of rotation) are arranged.
- an antenna 3 for example a millimeter wave antenna
- a parachute cassette 4 for example for a parachute of rotation
- the warhead 2 is usually located in addition to the actual combat charge and a firing mechanism for activating the battle charge also connected to the antenna 3 electronic targeting device.
- an antenna protection cover 5 for example made of aluminum, is detachably fastened in front of it.
- the antenna protection cover 5 is connected to the parachute cassette 4 by means of three prestressed, elastic tension bands 7 (eg of rubber and / or spring steel) extending along the outside 6 of the warhead 2 and evenly distributed over the circumference of the warhead ,
- the compound of trained as a spring clips 8 parachute cartridge side ends of the elastic straps 7 takes place in the illustrated embodiment by engaging behind tab-shaped projections 9 in the outer wall of the antenna cover 5 recessed recesses 10, so that upon detachment of the parachute 4 of the warhead 2, the parachute cartridge side ends 8 of the elastic straps 7 become free and the antenna protection cover 5 is dropped by the bias of the elastic tension bands 7, as this Fig.2 is removable.
- the antenna protection cover and the elastic straps can also be made of plastic.
- the attachment of the parachute cartridge-side ends of the elastic tension bands may be connected to the parachute cartridge or the warhead via another suitable mechanism, such that when the parachute cartridge is detached from the warhead, the parachute cartridge-side ends become free and the antenna protection cover is released by the bias of the parachute cartridge Tension straps is dropped, or separated by the axial delay (when releasing the parachute).
