Definitions
- the invention relates to a penetrator for a projectile, with a terminal ballistic main body and with at least one signal line led from a rear end to a front end of the main body, wherein the main body has at least one external thread.
- the invention relates to the use of such a penetrator for combating an armoured target, in particular an armoured target with reactive armour. Furthermore, the invention relates to a projectile, in particular a sub-caliber impact projectile, comprising such a penetrator and a sabot.
- the invention relates to a cartridge-loaded ammunition comprising such a projectile and a propellant charge.
- a penetrator is a part of a projectile that achieves its effect, namely at least the penetration of a target's armor and in particular the associated destruction of the target, through kinetic energy alone.
- the structure and function of penetrators are known from the state of the art.
- a penetrator of the type mentioned at the beginning is disclosed, for example, in the published patent application DE 10 2019 126 604 Al.
- the penetrator has a main body, which is usually made of a solid material, e.g. a tungsten heavy metal.
- the main body is the terminal ballistic part of the penetrator, which is usually cylindrical with a tapered front side. To improve the (external) ballistic flight phase of the penetrator, i.e.
- the penetrator also has a tail unit, which is attached to one of the tapered front sides (tip or front) opposite the front of the main body (rear).
- the tail unit serves or is designed to aerodynamically stabilize the penetrator during the (external) ballistic flight phase and thus to ensure the accuracy of the penetrator.
- target information in particular flight time
- target information must be sent from a fire control computer to a control unit that is usually located in the area of the front end of the main body, i.e. the tapered front side.
- a control unit that is usually located in the area of the front end of the main body, i.e. the tapered front side.
- This is usually done with the help of a signal line that runs along a central longitudinal axis of the penetrator from the rear end, i.e. the end with the tail assembly (tail), to the front end of the main body (tip or front).
- This signal line receives the signals from the fire control computer at the rear end and forwards them to the control unit.
- the signal line is guided inside the main body, usually through a cavity extending along the longitudinal axis of the main body. Due to the space required to form the cavity
- this solution entails the problem that the mechanical properties of the penetrator, in particular its power-to-weight ratio and mechanical stability, are negatively affected, so that the penetrator has a lower penetration effect.
- the signal line is embedded in a combustible casing which contains the penetrator and forms a projectile together with the penetrator.
- this solution has adverse effects on environmental resistance, i.e. the stability of the signal line attachment against environmental influences, as well as the residue-free combustion of the casing together with the signal line after the projectile or penetrator has been fired.
- the signal cable is laid within a sabot segment of the penetrator.
- Such sabot segments are generally known.
- this solution has disadvantages with regard to the durability and stability of the attachment of the signal cable as well as the symmetrical opening of the sabot segment after passing through the muzzle, which has a negative impact on the hit performance.
- the object of the invention is to provide a penetrator which is improved in comparison, whereby in particular a routing of the signal line and so that a signal guide is provided which affects the main components of the projectile or penetrator as little as possible.
- the object is achieved by a penetrator with the features of claim 1. This is characterized in that the signal line is guided at least in sections, i.e. over a section of the signal line, along a thread root of the external thread.
- the penetrator can continue to be designed with advantageous mechanical properties without being influenced by the signal line.
- the signal line By guiding the signal line along the thread base, there are essentially no adverse effects on a sabot segment assigned to the penetrator, a sleeve or the penetrator itself, in particular its main body.
- This provides a simple and cost-effective solution for guiding the signal line, which uses the properties of the main body that are already present, i.e. the external thread that is always present.
- the external thread which is present as standard is used for guiding the signal line, which does not interfere with the penetrator or elements associated with the penetrator.
- the external thread is arranged in the area between the two ends or at one of the two ends or the corresponding end of the main body is through the External thread is formed or at least co-formed.
- the external thread thus extends over areas of the outer wall (surface) of the main body or is formed in the outer wall, in particular formed integrally with the outer wall.
- the thread root is understood to mean a bottom of the external thread (core diameter), i.e. so to speak (looking from the outside at the external thread) the deepest point or points of the incisions in the main body forming the external thread.
- the signal line is guided in particular along the central longitudinal axis at least in sections on the outside (e.g. inside or underneath a vulcanization of the main body and/or inside the penetrator (in a corresponding channel)). This advantageously results in a durable and secure routing of the signal line.
- the penetrator or the main body can have several external threads, particularly of the same type (left-hand thread/right-hand thread).
- the diameter of the respective external threads can be different from one another.
- a first external thread which is arranged in the region of the front end of the main body and serves to attach a penetrator tip, can have a smaller outer diameter ( is therefore narrower ) than a second external thread , which is arranged in particular in the middle region of the main body and is designed for fastening a sabot .
- the signal line can be firmly attached to the thread base. This advantageously ensures a simple, cost-effective and yet secure attachment of the signal line.
- the signal line can be fastened to the thread base by means of glue or adhesive.
- glue or adhesive Alternatively or additionally, a force-fitting and/or form-fitting fastening is conceivable.
- the signal line is designed as a flat strand.
- the signal line advantageously requires a relatively small amount of space, which means that the function of the external thread is only negligibly affected, if at all.
- flat means that the strand has a rectangular or oval cross-section.
- the strand is placed on the thread base in such a way that it protrudes as little as possible (with the flat side or towards the base/inserted "across" into the thread base). In other words, the strand rests with its flat side on the thread base and only extends "upwards” with its narrow side.
- the strand has dimensions of less than or equal to 0.35 mm in its cross-section.
- the longer external dimension of the cross-section can have a dimension of less than or equal to 0.35 mm.
- the thread base is recessed or has a recess to accommodate the signal line. This results in the advantage of a particularly space-saving, secure arrangement of the signal line, which at the same time only has an insignificant impact on the functionality of the external thread.
- recessed means that the thread base is deeper (in particular 0.6 - 1 mm deeper) than would actually be necessary to accommodate a thread that is complementary to the external thread and that interacts with it when used as intended.
- the thread base has an additional material removal that is formed, for example, during the manufacture of the penetrator or main body.
- the thread root is recessed, i.e. the external thread has a reduced core diameter in relation to its nominal diameter (core diameter smaller than is usually the case for a (e.g. metric) thread of this size).
- the recess in question is a precisely fitting recess in the thread base for the strand, i.e. a recess into which the strand can be inserted precisely.
- the recess enables in particular a positive fastening of the strand to the thread base.
- the penetrator can preferably have a penetrator tip thread as an external thread, in particular a first external thread, which is designed for fastening a penetrator tip and is arranged in the region of the front end (front).
- a penetrator tip thread as an external thread, in particular a first external thread, which is designed for fastening a penetrator tip and is arranged in the region of the front end (front).
- the penetrator tip thread is therefore arranged at the front end of the main body.
- the front end can also be formed by the penetrator tip thread or at least be co-formed.
- the penetrator tip thread is designed to be complementary to a corresponding internal thread of the penetrator tip.
- the penetrator has a sabot thread as an external thread, in particular a second external thread, which is designed for fastening a sabot and in the area between the rear end and the front end of the main body.
- a sabot thread as an external thread, in particular a second external thread, which is designed for fastening a sabot and in the area between the rear end and the front end of the main body.
- the sabot thread is formed in one piece with the main body, for example cut into its outer shell or casing surface.
- the sabot thread is thus formed complementarily to a corresponding internal thread of the sabot.
- the penetrator can have both the penetrator tip thread and the sabot thread. This results in the advantages already mentioned above with regard to the two threads.
- the projectile with the features of claim 8 has a penetrator and a sabot and is characterized in that the penetrator is designed according to the invention as described above. This results in the advantages already mentioned in this regard.
- the projectile can preferably be designed as a sub-caliber kinetic energy projectile.
- the cartridge ammunition with the features of claim 9 has a projectile and a propellant charge and is characterized in that the projectile is designed according to the invention as described above. This results in the advantages already mentioned.
- the penetrator according to the invention according to claim 10 it is used to combat an armoured target, in particular an armoured target with reactive armour.
- the penetrator has the advantages already mentioned above.
- Figure 1 is a simplified schematic representation of an advantageous penetrator
- Figure 2 is an enlarged cross-sectional view of an external thread of the penetrator in the region of a section G in Fig. l.
- FIG 1 shows a simplified schematic representation of a penetrator 1 for use in combating an armoured target.
- the penetrator 1 forms a projectile 3 which is designed in particular as a sub-calibre kinetic energy projectile.
- the projectile 3 in turn is together with other elements not shown in Figure 1 for reasons of clarity.
- the penetrator 1 achieves its target-attacking effect solely through kinetic energy.
- the penetrator 1 has a cylinder- or pin-shaped main body 5 which extends along a central longitudinal axis L and is preferably formed at least partially from a heavy metal, in particular tungsten heavy metal.
- the main body 5 has a front end 6 (front) (facing the target to be attacked, i.e. aligned in the direction of flight) and a rear end 7 (tail), with a tail unit 8 being attached, for example in a material-locking manner, to the rear end 7.
- the tail unit 8 serves or is designed to aerodynamically stabilize the main body 5 or penetrator 1 during an (external) ballistic flight phase.
- the (external) ballistic flight phase essentially involves the flight path of the penetrator 1 starting from the mouth of a projectile barrel (not shown here), from which the penetrator 1 or the projectile 3 is fired, until it impacts the target to be attacked.
- a first external thread 9 is designed as a sabot thread 9' and, as can be seen in Figure 1, is arranged in the middle area, i.e. between the front end 6 and the rear end 7, of the main body 5.
- the sabot thread 9' is preferably designed as a metric thread (left-hand thread or right-hand thread) and complementary to a corresponding internal thread of the sabot 2. The interaction of the sabot thread 9' and the corresponding internal thread of the sabot 2 enables a positive fastening of the sabot 2 to the main body 5.
- the sabot thread 9 ' and the penetrator tip thread 9 '' are of the same design, but can of course also be different from one another.
- the penetrator 1 when the penetrator 1 is used as intended, it is often necessary to transmit signals issued by a fire control computer to a control unit usually arranged in the area of the front end 6 of the penetrator 1.
- the penetrator 1 has a signal line 12 which is guided from the rear end 7 to the front end 6 along the central longitudinal axis L of the main body 5 or penetrator 1.
- the signal line 12 is shown as an example and in a highly simplified manner.
- the signal line 12 can be routed at least in sections both inside and outside the main body 5.
- the signal line 12 is designed as a flat stranded wire 12.
- Figure 2 shows an enlarged image of an area G from Figure 1, showing a simplified cross-sectional view of the external thread 9, in this case the sabot thread 9'.
- the view according to Figure 2 and the guidance of the strand 12 shown there can be transferred analogously to the penetrator tip thread 9''.
- the strand 12 is guided along the thread base 13.
- the thread base 13 is the bottom or the deepest point of the external thread 9.
- the strand 12 is placed with its flat side on the thread base 13.
- the thread base 13 is recessed. This means that the thread base 13 is deeper than would actually be necessary to accommodate the complementary internal thread 14, so that the thread base 13 has material removed.
- the strand 12 can advantageously be guided along the thread base 13 without the interaction between the external thread 9 and the internal thread 14 being impaired.
- the strand 12 is advantageously protected from external influences by the internal thread 14.
- the thread base has a recess 15 associated with the strand 12 and essentially complementary to it, into which the strand 12 can be inserted.
- the recess 15 is shown in Figure 2 using dashed lines.
- the recess 15 advantageously enables not only a protected, but also a positive fastening or guiding of the strand 12 on the thread base 13.
- the strand 12 is firmly attached to the thread base 13, for example by gluing. Outside the thread base 13, the strand 12 can be guided along the main body 5 in a known manner, for example in a vulcanization, on the outer surface of the main body 5 or through a channel in the interior of the main body 5.
