Description

[0001] The invention relates to a projectile comprising a housing with a housing base body and at least one housing segment arranged on a longitudinal axis of the housing base body, which is telescopic relative to the housing base body between a first position and at least a second position, in which an electrical device is arranged.

[0002] Such projectiles, used particularly for firing from shoulder-fired handguns, are generally known from the prior art. To move the projectile from its initial position to its operational position, such systems typically feature a telescopic tube or tube segments that can be extended or retracted by the user along the length of the projectile. An electrical device, for example, with a shaped charge or a shaped charge fuse, is usually located in one of the described tube segments. However, an electrical device with a different operating system, such as an explosive, can also be arranged.

[0003] From GB 957 956 A, for example, a shaped charge projectile is known which is equipped with an extendable rod. This rod can be extended, for example, by means of a tensioned spring or by supplying gas from the ogive of the projectile. A contact element for sensing an impact and transmitting a signal via wires to an ignition circuit can be provided at the tip of the rod.

[0004] DE 36 03 497 C1 shows a shaped charge warhead with an impact fuze attached to one end of a spacer. The warhead casing comprises the shaped charge, a metallic insert, and a shaped charge cover. The cover is connected to a guide in the form of a sliding bushing into which the spacer can be telescopically inserted. The guide is provided externally with bearing surfaces for radial bearings, which ensure the individual rotation of a control unit (1) that extends in a ring around the guide.

[0005] German patent DE 39 42 841 A1 discloses a tandem warhead with a casing containing a shaped charge and a spacer extendable from the casing, wherein a pre-shaped charge is arranged in the tubular spacer. The spacer can be locked via a spacer tube guide. It is mentioned that ignition can be initiated via a sensor built into the tip of the spacer.

[0006] From JP 4 044 199 B4, a fuze with a fuze body is known that can be attached to a projectile body by screwing it in. Inside the fuze body are, among other things, a folded spring, a transmission wire, and an ignition device. After the projectile is fired, a cover element releases, allowing the spring to unfold and extend an impact sensor, thereby tensioning the transmission wire. Impact on a target releases the tension on the transmission wire; as a result of this release, or a signal from the impact sensor, a safety device of the ignition system is deactivated, allowing detonation to occur.

[0007] Since the previously described tube segments must be extended axially by the user to move them between the home and operating positions, and are typically locked in the extended position by a rotational movement, connecting the electrical device to the electrical components of the projectile, the weapon, or the launching device from which it is fired is very limited. Repeated movement of the projectile from the home to the operating position, especially if the tube segments are rotated repeatedly in one direction—for example, due to unintentional rotation, an unintended rotation, or if a threaded connection cannot be found—could lead to twisting and damage to electrical cables and the like.

[0008] The invention is based on the objective of providing an improved projectile in comparison.

[0009] The problem is solved by a projectile having the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

[0010] As described, the invention relates to a projectile comprising a housing with a housing base and at least one housing segment that is movable relative to the housing base between a first position and at least a second position. The housing segment is "telescoped" to move between the home position and the operating position, or between the first and second positions. In the context of this application, "telescoping" means moving relative to the housing base, i.e., in particular, pushing the housing segment in or out of the housing base or out of at least one further housing segment, or into at least one further housing segment.

[0011] The projectile may be designed to have exactly one housing body and exactly one housing segment, wherein the housing segment can be extended from the housing body to move the projectile into the operating position and the housing segment can be inserted into the housing body to move the projectile into its stowed position. For example, in a stowed state, in which the projectile is being transported, a retracted or collapsed position may be assumed in which the at least one housing segment is inserted into the housing body, or several housing segments are inserted into each other and into the housing body. To move from the stowed position to the operating position, the user can telescope the projectile by extending the at least one housing segment from the housing body and locking it in the operating position.

[0012] The invention is based on the finding that the electrical device, in particular part of an ignition device, can be connected or is connected by means of a line, in particular an electrical and / or optical line, to a control device and / or a power source, in particular arranged inside or outside the housing body, wherein at least one part of the electrical device coupled to the line is rotatably mounted relative to the housing segment. The invention thus proposes connecting the electrical device to a control device by means of a line. The control device can be a control device of the projectile, for example a control device that is associated with the ignition device, for example a main shaped charge device, or with another component of the projectile, for example a pilot shaped charge device.The control device can also be a general term for various interfaces that can be operated or connected to the line. The line can therefore carry not only an electrical signal or a supply of electrical power, but also a data line. As described at the beginning, the line can be implemented as an electrical line, an optical line, or a combination of both. The line can also be constructed entirely or partially with fiber optic strands, particularly optical fiber strands, to enable faster data transmission from one area to another, for example. The line can thus be used or configured for any transmission of electrical power or information.The control unit can therefore be designed accordingly, so that in the simplest case it can be a connector element, for example for a diagnostic connector or a connection to an electrical power source. The control unit can, for example, be located inside the housing. It is also possible for a control unit to be located outside the housing. The cable is routed accordingly to establish the connection to the control unit.

[0013] The term "electrical device" can refer to any device arranged in or on the housing segment. The electrical device can include, among other things, any selection or combination of electrical and / or electronic components and parts. The electrical device can also include one or more electrically triggered ignition devices, such as a force element. In one example, the electrical device can include an ignition device, particularly for a part of the ignition device arranged in the housing segment. The rotatable mounting of the conductor or the part of the electrical device coupled to the conductor relative to the housing segment simultaneously causes the housing segment to also be rotatably mounted relative to the part of the electrical device coupled to the conductor.In other words, the description can be modified or transferred to state that not only the part of the electrical device coupled to the line is rotatably mounted relative to the housing segment, but also or instead the housing segment is rotatably mounted relative to at least one part of the electrical device coupled to the line.

[0014] To protect the conductor, for example a connecting cable, from the damage described above, at least the part of the electrical device coupled to the conductor must be rotatable relative to the housing segment in which it is mounted, or the housing segment in which the electrical device is housed must be rotatable relative to the part of the electrical device coupled to the conductor. Thus, the part of the electrical device coupled to the conductor is held in place relative to the housing, while the housing segment can rotate, for example, to be fixed in a working position by tightening a threaded connection.

[0015] This achieves a decoupling of the cable and the electrical component in the direction of rotation. In other words, the housing segment containing the electrical component can be rotated freely around its longitudinal axis without the cable twisting or twisting. If the housing segment is rotated, for example, to fix it in its axial position in the operating position, the part of the electrical component coupled to the cable, particularly through its coupling to the housing base, remains stationary relative to the housing segment, thus preventing the cable from twisting. This allows the unit to be moved from its home position to its operating position and vice versa as often as desired.It is also possible that at least one housing segment can be rotated arbitrarily by a user without risking damage to the cable, for example, if the thread cannot be located. The cable can be an electrical cable and / or an optical cable.

[0016] The described projectile may be provided with a housing-mounted guide sleeve in which the housing segment is guided during movement along its longitudinal axis. The electrical device is coupled to or received in a receiving device, the housing segment being rotatable relative to the receiving device. The receiving device is fixed circumferentially to the guide sleeve and is movable longitudinally together with the housing segment. The guide sleeve may, for example, be formed as part of the housing body or as a sleeve within the housing body and fixedly connected to it. Thus, the housing segment can be extended from or inserted into the guide sleeve during movement between the operating position and the home position.

[0017] Specifically, when using a single housing segment, the mounting device on which the electrical device is arranged or in which the electrical device is housed can be coupled circumferentially to the guide sleeve, thus preventing rotation of the mounting device and therefore of the electrical device relative to the guide sleeve. However, the coupling between the mounting device or the electrical device and the guide sleeve allows movement of the electrical device together with the housing segment in which the electrical device is housed in the longitudinal direction, so that the electrical device together with the housing segment can be telescoped relative to the guide sleeve and thus relative to the housing body.The housing segment can be rotated arbitrarily relative to the receiving device, so that a user can rotate the housing segment while the receiving device and thus the electrical device remain stationary.

[0018] The guide sleeve can have a (first) receiving element, in particular a groove extending longitudinally in the guide sleeve and received in an inner surface of the guide sleeve, wherein the receiving device has a (first) engagement element engaging in the receiving element, in particular a nose or rib extending radially. As described, the receiving device is coupled to the guide sleeve in such a way that rotation between the receiving device and the guide sleeve in the circumferential direction is prevented, but axial displacement along the longitudinal direction between the guide sleeve and the receiving device is possible, so that the receiving device together with the housing segment can be pulled out of or pushed into the guide sleeve.When the housing segment is fixed by rotating the housing segment relative to the housing base body, the receiving device remains in the same orientation in the circumferential direction relative to the guide sleeve.

[0019] As already mentioned, the projectile can have exactly one housing segment that can be extended from or inserted into the housing base. It is also possible for the projectile to have any number of housing segments, in particular exactly two housing segments. Accordingly, at least two housing segments arranged coaxially on the longitudinal axis of the housing base, and telescoping relative to the housing base between a first position and at least a second position, can be provided, wherein the electrical device is arranged in a first, in particular distal, housing segment, wherein the first housing segment is rotatably mounted relative to the at least one part of the electrical device coupled to the line, and the at least one part of the electrical device coupled to the line is coupled to the first housing segment in the longitudinal direction.

[0020] In this application, the individual telescoping components of the projectile are referred to as casing segments. These can also be called casing elements, "spike elements," or "spike segments." The projectile incorporates an electrical device in at least one casing segment, which may, for example, provide at least part of an ignition device. The terms "proximal" and "distal" describe the casing segments in terms of their arrangement relative to the main casing body, for example, in a projectile's operational position. The "proximal" casing segment is thus understood to be the one that is closest to the main casing body, particularly in the axial direction. Accordingly, the "distal" casing segment is understood to be the one that is furthest from the main casing body and carries the electrical device.

[0021] In its simplest form, the projectile has only one housing segment, which can be extended from or inserted into the main housing body. In a variant where the projectile has exactly two housing segments, the segment closer to the main housing body (in its operating position) is the "proximal housing segment," while the segment further away is the "distal housing segment." Any number of additional housing segments can be provided between the proximal and distal housing segments. The distal housing segment, which carries the electrical components, is called the "first" housing segment, and the proximal housing segment is called the "second" housing segment.In the embodiment with exactly two housing segments, the distal housing segment carries the electrical device, with the proximal housing segment being arranged longitudinally between the distal housing segment and the housing base body.

[0022] Following further development of the projectile, at least two housing segments are designed to be rotatable relative to each other and axially movable in a home position, and axially fixed in a working position. As described, the user can move the projectile from the home position to the working position before use. For this purpose, the housing segments are extended from the main housing body or relative to each other and fixed in the extended position. This ensures that the housing segments are axially fixed in the working position, thus forming a stable arrangement on the main housing body or on each other. The fixing of the housing segments is achieved primarily by a rotational movement. Conversely, the axial fixation can be released by a counter-rotating movement, for example, to move the projectile from the working position back to the home position.Despite the rotational movement, the mounting of the part of the floor coupled to the cable ensures that the cable is not twisted or wound, so that it cannot be damaged or otherwise negatively affected by the rotational movements.

[0023] According to one embodiment of the projectile, an intermediate sleeve can be mounted in the second housing segment, i.e., the proximal housing segment, particularly radially inside. The intermediate sleeve is coupled to the guide sleeve in the circumferential direction and fixed axially to the proximal housing segment, while being rotatable circumferentially relative to the proximal housing segment. As described, the guide sleeve is, for example, a sleeve integrated into the housing body, in which the proximal housing segment is arranged and guided, at least partially. The guide sleeve can, for example, be designed as a separate sleeve within the interior of the housing body. It is also possible for the guide sleeve to be formed, at least partially, by an inner shell or surface of the housing body.In other words, the guide sleeve can be designed as a separate sleeve located within the housing body, or the housing body itself can form the guide sleeve on its inner surface. Designing the guide sleeve as a separate sleeve within the housing body allows for an increase in the maximum achievable draw length, as the guide sleeve can extend to an edge of the housing body, for example, a conical section of the housing body that slopes in the direction of flight or launch.

[0024] The intermediate sleeve can be designed as a separate component or considered part of the proximal housing segment, since it is axially coupled to the proximal housing segment. Therefore, the intermediate sleeve, along with the proximal housing segment, is axially movable, for example, during transitions between the operating and home positions. Circumferentially, the intermediate sleeve is coupled to the guide sleeve, meaning it cannot be rotated relative to the guide sleeve. However, the intermediate sleeve is rotatably mounted circumferentially to the proximal housing segment, so while it is axially connected to the proximal housing segment, it is circumferentially decoupled and thus rotatable relative to it.This allows the proximal housing segment to be rotated relative to the housing base and the intermediate sleeve, particularly for fixing purposes.

[0025] The projectile can be further developed such that the part of the electrical device coupled to the conductor, in particular the receiving device for the electrical device, is coupled to the intermediate sleeve. The coupling between the part of the electrical device and the intermediate sleeve can be circumferential, so that the part of the electrical device, specifically the receiving device, cannot be rotated relative to the intermediate sleeve. Since, as described above, the intermediate sleeve is coupled to the guide sleeve circumferentially, according to this embodiment, the part of the electrical device that is connected to the conductor, for example via the receiving device, is also coupled to the guide sleeve and thus firmly connected to the housing body circumferentially.The arrangement of the part of the electrical device in the axial direction is, as already described, on the distal housing segment, so that the part of the electrical device is movable in the axial direction together with the distal housing segment.

[0026] Thus, the distal housing segment can be moved axially relative to the proximal housing segment and rotated circumferentially relative to it. The proximal housing segment can, accordingly, be moved axially independently of the distal housing segment and rotated relative to the housing base. Likewise, the distal housing segment can be moved axially independently of the proximal housing segment and rotated relative to the housing base.

[0027] The guide sleeve is always rigidly connected to the housing body in both the axial and circumferential directions, or is an integral part thereof. The intermediate sleeve, arranged radially inside, and in particular concentrically inside, the proximal housing segment, is axially movable together with the proximal housing segment and coupled to the guide sleeve in the circumferential direction. At least the part of the electrical device located in the distal housing segment is coupled to the intermediate sleeve in the circumferential direction and thus axially movable with the distal housing segment, but decoupled from the distal housing segment in the circumferential direction. The described design thus allows the individual housing segments to be telescoped and rotated, in particular to fix them or to release the fixation.At the same time, it is ensured that the cable cannot be damaged by the rotational movements, since its connection point to the electrical device, together with the intermediate sleeve and the guide sleeve, is firmly connected to the housing in the circumferential direction and therefore cannot rotate with the housing segments.

[0028] As previously described, the projectile's guide sleeve can have a first receiving element, in particular a first groove extending in the axial direction. In an embodiment with more than one housing segment, instead of a direct coupling between the guide sleeve and the first engagement element provided on the receiving device, the receiving device can be coupled to the intermediate sleeve, and the intermediate sleeve in turn can be coupled to the guide sleeve. For this purpose, the intermediate sleeve can have a second receiving element, in particular a second groove extending in the axial direction. The first engagement element of the receiving device can engage in the second receiving element, with the intermediate sleeve having a second engagement element, in particular a lug extending in the radial direction, which engages in the first receiving element of the guide sleeve.Accordingly, the engagement between the second engagement element of the intermediate sleeve and the first receiving element in the guide sleeve achieves the coupling of the intermediate sleeve to the guide sleeve in the circumferential direction, and the engagement between the first engagement element on the receiving device and the second receiving element in the intermediate sleeve ensures the coupling between the receiving device and the intermediate sleeve in the circumferential direction. The free movement of the individual components in the axial direction is maintained, as the engagement elements can be moved freely in the axial direction within the receiving elements.

[0029] The receiving elements can be implemented, for example, as grooves on an inner surface of the respective element, such as a groove on the inner surface of the guide sleeve or a groove in the inner surface of the intermediate sleeve. Accordingly, the engagement elements are implemented as lugs or ribs, or generally as radially projecting protrusions that engage with the receiving elements. The engagement elements can thus move axially within the receiving elements, but prevent rotational movement or relative circumferential movement of the projectile components coupled to one another via the receiving element and engagement element.

[0030] As described, each of the housing segments can be moved both axially and circumferentially, i.e., extended or retracted, and rotated about the longitudinal axis of the projectile. The at least one housing segment can have a fixing area to secure it in its operating position relative to the housing body. If more than one housing segment is provided, the at least two housing segments can each have a fixing area designed to fix the respective housing segment by a rotational movement in a first direction and to release it by a rotational movement in a second direction, wherein the proximal housing segment can be fixed to the housing body and the distal housing segment can be fixed to the axially adjacent housing segment, in particular the proximal housing segment.

[0031] As described, any number of adjacent housing segments can be arranged between the proximal and distal housing segments. It is also possible, in principle, to provide a housing segment that is axially further away from the housing body and positioned further away from the housing body than the distal housing segment. However, in this application, the distal housing segment is defined as the housing segment that carries the electrical device and, particularly in its operating position, is located further away from the housing body than the proximal housing segment.

[0032] The fixing area can have a corresponding device on each housing segment or the corresponding section of the projectile component to which the housing segment is coupled, enabling axial fixing. The fixing area can, in particular, have a threaded section. Fixing via a bayonet mechanism or similar mechanisms that open and close via a rotary motion is also possible. For example, an internal thread can be provided on an inner surface of the fixing area on the housing body, and a corresponding external thread can be provided on an outer surface of the proximal housing segment.Similarly, a threaded area can be implemented in a fixing area between the distal housing segment and the proximal housing segment or correspondingly adjacent housing segments, for example an external thread on an outer surface of the distal housing segment which can engage with an internal thread arranged on an inner surface of the proximal housing segment.

[0033] The housing body can further comprise a bearing area in which at least one housing segment, for example, the proximal housing segment in the case of more than one housing segment, is supported, particularly by means of a retaining device. At least the proximal housing segment can, if more than one housing segment is provided, have a bearing area in which the axially adjacent housing segment, particularly the distal housing segment, is supported, particularly by means of a retaining device. The bearing areas enable the individual housing segments to be supported. For this purpose, the housing body comprises a bearing area in which the proximal housing segment can be supported. Each of the individual housing segments, except for the distal housing segment or the housing segment furthest away from the housing body in the axial direction, has a corresponding bearing area.

[0034] The bearing area provides, in particular, a surface on the interior or inner circumference in which the axially adjacent housing segment can rest coaxially. Retaining elements, such as seals, especially O-rings, can be provided in the bearing areas. These retaining elements can ensure that the housing segments remain inserted into one another until the user actively extends or telescopes them. The retaining elements can thus prevent unintentional movement of the housing segments relative to each other and relative to the housing body, and necessitate extension to move the projectile from its home position to its operating position.

[0035] Further modification of the projectile may include a communication interface. This interface may be integrated into the control unit described above or implemented separately. Alternatively, the control unit itself may function as the communication interface. The communication interface may, for example, be located within the housing and configured to connect the cable to at least one device, in particular an ignition device (e.g., a main shaped charge device), a diagnostic device, a fire control device, a power source, and / or a sensor. Essentially, the communication interface is designed to connect the electrical device to another internal or external device via the cable.The communication interface can, in principle, transmit energy or corresponding switching signals via the line.

[0036] For example, energy can be transferred to the electrical equipment, such as to a component of an ignition device for a pilot-shaped charge detonator, to trigger it. The diagnostic equipment allows for post-production testing. Communication with a fire control unit enables the exchange or transmission of relevant data, or the electrical power supply, for example from the fire control unit's battery, can also be used for the electrical equipment. Another possibility is to connect the electrical equipment to the ignition device, such as a main shaped charge device, via a cable. In particular, the control unit of the main shaped charge device can also be used for the electrical equipment, which can also be an ignition device for, for example, a pilot-shaped charge device or a force element.This offers the particular advantage that only one control unit can be used for both the main shaped charge device and the electrical system. In other words, everything required for the electrical system can be routed to the distal housing segment via the cable.

[0037] In a further embodiment of the projectile, a disarming device may be provided, designed to disarm at least the electrical component, for example, part of an ignition device, particularly based on two physically independent mechanisms. The disarming device may have several disarming elements based on physical mechanisms. For example, a detection device may be provided that can sens whether the projectile has left the weapon or the barrel from which it is fired. Further mechanisms may include a gas pressure switch that detects whether propellant gas pressure is present at the projectile. Other physical mechanisms may, for example, represent a centrifugal disarming mechanism that, for instance, in the case of a spin-type projectile, can detect a phase of the projectile's flight and thus disarm it.Other safety mechanisms can also be electronic, for example time-controlled, position-controlled or distance-controlled.

[0038] The device may also include triggering mechanisms that can initiate a charge of a then released and armed firing device, such as a proximity sensor or an impact switch in the form of a firing pin or a switch.

[0039] Furthermore, the invention relates to a firing device, in particular a shoulder-mounted firing device, comprising at least one projectile as previously described. The described firing device may, in particular, be a handgun.Furthermore, the invention relates to a projectile comprising a housing with a housing base body and at least two housing segments arranged coaxially on a longitudinal axis of the housing base body and telescopically extendable relative to the housing base body between a first position and a second position, wherein a pre-charging device is arranged in a distal housing segment, the pre-charging device having a pre-charging fuze, wherein the pre-charging device, in particular the pre-charging fuze, is connectable or connected by means of an electrical line to a control device, in particular arranged in the housing base body, wherein at least one part of the pre-charging device coupled to the electrical line is rotatably mounted relative to the distal housing segment.

[0040] All the advantages, details and features described in relation to the projectile are fully transferable to the launching device.

[0041] The invention is explained below with reference to exemplary embodiments and the figures.

[0042] Fig. Figure 1 shows a projectile 1, in particular a front part of the projectile, for use in a launching device not shown, in particular a shoulder-launched launching device, for example a handgun. The projectile 1 can be described, for example, as an anti-tank projectile.

[0043] The story 1 comprises a housing 2 with a housing base 3 and a housing segment 5 arranged concentrically on a longitudinal axis 4 of the housing base 3, which is telescopic relative to the housing base 3 between a first position and a second position. The housing segment 5 is isolated in Fig. Figure 14 illustrates this. In principle, any number of housing segments 5 can be provided, as described below with reference to the second embodiment. In the following description of the Fig. 1-4 the projectile has exactly one housing segment 5.

[0044] The housing segment 5 includes an electrical device 6. The electrical device 6 includes, for example, a portion of an ignition device 7, which is intended for igniting a shaped charge (not shown in detail). This portion of the ignition device 7 is merely exemplary and can be replaced or supplemented with any other electrical and / or electronic unit. The electrical device 6 can generally be arranged on a receiving device 8 or at least partially received therein. In principle, the projectile 1 can include further detonators and charges, for example, a main shaped charge, which are generally known from the prior art and are not shown or described here for the sake of simplicity.

[0045] In the Fig. In the situation depicted in Figures 1-3, the projectile 1 is in a fully extended state, which can also be described as the operational position. In this position, the projectile 1 can, for example, be fired. It is evident that the housing segment 5 is fully extended in the axial direction with respect to the longitudinal axis 4 and can be fixed in the axial direction. The basic position, which is shown in Fig. As shown in 4, starting from the in Fig. The operating position shown in 1-3 can be assumed, namely by loosening and inserting the housing segment 5 into the housing base body 3, if necessary.

[0046] As in Fig. As shown in Figures 1-4, the housing base 3 has a guide sleeve 9 which is arranged inside the housing base 3. A section of the guide sleeve 9 is shown in isolation in a schematic longitudinal section in Fig. Figure 11 illustrates this. In the illustrated embodiments, the guide sleeve 9 is integrated as a separate sleeve into the interior of the housing base 3 and is fixedly connected to it, so that the guide sleeve 9 cannot be moved either axially or circumferentially relative to the housing base 3. Instead of a separate sleeve, the guide sleeve 9 can also be integrated into the housing base 3, so that the inner surface of the guide sleeve 9 can, for example, be designed as the inner surface of the housing base 3. The guide sleeve 9 has a first receiving element 10, which in this embodiment is designed as an axially extending groove that extends into the inner surface of the guide sleeve 9.

[0047] The housing segment 5 is located axially adjacent to the guide sleeve 9. The receiving device 8 has a (first) engagement element 11, which engages with the first receiving element 10 in the guide sleeve 9 and thus couples the receiving device 8 to the guide sleeve 9 in the circumferential direction. In other words, the guide sleeve 9 and the receiving device 8 are coupled to the housing base 3 with respect to rotational movement and are therefore not rotatable relative to the housing base 3. The first engagement element 11, together with the receiving device 8, is movable within the first receiving element 10 in the longitudinal direction, so that the receiving device 8, which is coupled to the housing segment 5 with respect to longitudinal movement along the longitudinal axis 4 and decoupled from it in the direction of rotation about the longitudinal axis 4, can be moved along the guide sleeve 9 together with the housing segment 5.

[0048] In this embodiment, the electrical device 6 is connected to a line 12. By decoupling the line 12, or the part of the electrical device 6, from the rotational movement of the housing segment 5, damage to the line 12, for example by twisting or tangling, is effectively prevented. The line 12 can be designed as an electrical line or include an electrical line and / or be designed as an optical line or include such an optical line. In particular, the line 12 can be a combination of an electrical line and an optical line. The line 12 can therefore be wholly or partially constructed or interspersed with fiber optic strands to, for example, enable faster data transmission from one area to another. The line 12 can thus be configured for any form of power transmission and / or data transmission.

[0049] To transfer floor 1 into the Fig. 1 shown position of use, in particular from the one shown in Fig. In the basic position shown in Figure 4, a user can pull the housing segment 5 axially out of the housing base 3 and then fix it in place. A rotary motion can be used for this purpose. The projectile 1 has a fixing area 13 for this purpose, which in this embodiment provides a threaded section or a bayonet fitting. The fixing area 13 is thus formed between the housing segment 5 and the housing base 3.

[0050] In other words, a user pulls the housing segment 5 out of the housing base 3 and rotates it relative to the housing base 3 so that the thread or bayonet fitting is screwed into the fixing area 13 and the housing segment 5 is fixed in its axial position. During such a rotational movement, no torque is transmitted to the line 12 because, as previously described, the part of the electrical device 6 that is coupled to the line 12 is firmly connected to the housing base 3 via the coupling to the receiving device 8 and the guide sleeve 9.

[0051] When the housing segment 5 is pulled out of or pushed into the housing base 3, the engagement element 11 can be moved axially in the receiving element 10. However, at all times, it is prevented that any circumferential movement of the housing segment 5 is transmitted to the receiving device 8 or to the part of the electrical device 6 that is coupled to the line 12.

[0052] Should the first floor be removed from the in Fig. 1 shown usage position in the in Fig. Once the housing segment 5 is returned to its initial position as shown in Figure 4, the fixing area 13 can be released, in particular by a rotational movement opposite to the rotational movement that fixed the housing segment 5. Here too, the engagement element 11, which is received in the receiving element 10, prevents circumferential movement of the electrical device 6, in particular of the housing of the ignition device 7. Once the fixing area 13 is released, the housing segment 5 can be inserted back into the housing base 3. During this process, the engagement element 11 moves axially within the receiving element 10.

[0053] Additionally, the floor 1 has a bearing area 14 in which the housing segment 5 is mounted. The bearing area 14 is formed on the housing base 3 and supports the housing segment 5. The bearing area 14 contains, in particular, sealing and retaining elements 15, such as O-rings, which support the housing segment 5 and, in particular, prevent unintentional displacement. The sealing and retaining elements 15 are designed such that axial movement of the housing segment 5 only occurs when force is applied by a user, thus preventing the housing segment 5 from shifting independently.

[0054] Line 12 can be connected to any type of control unit. Control signals or an electrical power supply to the electrical unit 6 can be transmitted via line 12. In principle, it is therefore possible to transmit all data, electrical signals, power supply, and the like from the housing 2 of the first floor to the housing segment 5, in particular to the electrical unit 6. The described configuration allows, for example, a control unit for controlling a main shaped charge device to also be used to control the electrical unit 6. It is also possible to use an external power source, such as the power source of a fire control unit or a launching device. Furthermore, the control unit can be used to perform diagnostics on the electrical unit 6.Another possibility is to transmit sensor values ​​or control signals to or from the electrical device 6.

[0055] Fig. Figure 5 shows a projectile 1 according to a second embodiment for use in a launching device (not shown), in particular a shoulder-launched launching device, for example a handgun. The projectile 1 can, for example, be described as an anti-tank projectile. The projectile 1 in Fig. 5-15 is basically the same as floor 1. Fig. 1-4. In contrast to the previously described floor 1 according to the first embodiment, the floor 1 according to the second embodiment has, in addition to the housing segment 5, a further housing segment 16. The housing segment 5 is therefore subsequently referred to as the second housing segment 5 or proximal housing segment 5 with reference to the second embodiment, and the housing segment 16 is referred to as the first housing segment 16 or distal housing segment 16. In principle, the designations "first housing segment" and "second housing segment" are arbitrary and can be changed. In the context of the following description, the first housing segment is referred to as the housing segment that carries the electrical device 6.

[0056] The floor 1 comprises a housing 2 with a housing base 3 and, in this embodiment, two housing segments 5, 16 arranged coaxially on a longitudinal axis 4 of the housing base 3 and telescopically extendable relative to the housing base 3 between a first position and a second position. The housing segments 5, 16 are insulated in Fig. 14, Fig. Figure 15 is shown. In principle, any number of housing segments 5, 16 can be provided. In the following description, housing segment 5 is referred to as the proximal housing segment 5 with respect to the housing body 3, and housing segment 16 is referred to as the distal housing segment 16.

[0057] The proximal housing segment 5 is the housing segment 5 that can be telescoped along the longitudinal axis 4 and is closest to the housing base body 3. In contrast, the distal housing segment 16 is axially spaced from the housing base body 3 and comprises the electrical device 6. The electrical device 6 is coupled to or housed within a receiving device 8. In principle, the projectile 1 can, in addition to the previously described and also optionally defined part of the ignition device 7, include further detonators and charges, for example, a main shaped charge, which are generally known from the prior art and are not shown or described here for the sake of simplicity.

[0058] In the Fig. In the situation depicted in Figures 5-7, projectile 1 is in a fully extended state, which can also be described as the operational position. In this position, projectile 1 can, for example, be fired. It is evident that the casing segments 5 and 16 are fully extended axially with respect to the longitudinal axis 4 and fixed in this axial direction. Fig. 8, Fig. Figure 9 shows intermediate states that occur when moving the projectile 1 between the operational position and the home position, which are described in Fig. As shown in 10, they can be taken. Fig. 8, Fig. The 9 intermediate states shown are merely examples. The transition between the basic position and the operating position can also be achieved by simultaneously moving the housing segments 5, 16 in the axial direction. Fig. Figure 8 shows, for example, housing segment 16 in a position inserted into housing segment 5, while housing segment 5 is extended. Conversely, in Fig. Figure 9 shows that housing segment 16 is extended and housing segment 5 is inserted. Fig. Figure 10 shows the projectile 1 in its home position, in which the housing segment 16 is in a state inserted into the housing segment 5 and the housing segment 5 is in a state inserted into the housing base body 3, i.e. both housing segments 5, 16 are fully inserted, in the sense of not telescoping.

[0059] As in Fig. As shown in Figures 5-10, the housing base 3 has a guide sleeve 9 which is arranged inside the housing base 3. A section of the guide sleeve 9 is shown in isolation in a schematic longitudinal section in Fig. Figure 11 illustrates this. In the embodiments shown, the guide sleeve 9 is integrated as a separate sleeve into the interior of the housing base 3 and is fixedly connected to it, so that the guide sleeve 9 cannot be moved either axially or circumferentially relative to the housing base 3. Instead of a separate sleeve, the guide sleeve 9 can also be integrated into the housing base 3, so that the inner surface of the guide sleeve 9 can, for example, be designed as the inner surface of the housing base 3. As already described, the guide sleeve 9 has a first receiving element 10, which in this embodiment is designed as an axially extending groove that extends into the inner surface of the guide sleeve 9.

[0060] Adjacent to the guide sleeve 9 in the axial direction is the proximal housing segment 5, to which an intermediate sleeve 17 is arranged coaxially inside. The intermediate sleeve 17 is insulated in Fig. Figure 13 shows the intermediate sleeve 17 having a second engagement element 18, which engages with the first receiving element 10 in the guide sleeve 9 and thus couples the intermediate sleeve 17 to the guide sleeve 9 in the circumferential direction. In other words, the guide sleeve 9 and the intermediate sleeve 17 are coupled to the housing body 3 with respect to a rotational movement and are therefore not rotatable relative to the housing body 3. The intermediate sleeve 17 also has a second receiving element 19, which, as already described with respect to the guide sleeve 9, is formed as an axially extending groove on the inner surface of the intermediate sleeve 17. The first engagement element 11, which is coupled to the electrical device 6, for example to the receiving device 8, engages in the second receiving element 19. The receiving device 8 and the electrical device 6, in particular the part of the ignition device 7, are best described in Fig. 12 shown.

[0061] The part of the electrical device 6 coupled to the second engagement element 18, which is arranged in the distal housing segment 16, is thus coupled to the intermediate sleeve 17 and the guide sleeve 9 in the circumferential direction and is therefore also rotationally fixed relative to the housing body 3. In this embodiment, the electrical device 6 is again connected to a cable 12. By decoupling the cable 12, or rather the part of the electrical device 6, from the rotational movement of the housing segments 5, 16, damage to the cable 12, for example by twisting or twisting, is effectively prevented.

[0062] To transfer floor 1 into the Fig. 5 shown usage position, in particular from the one in Fig. In the basic position shown in Figure 10, a user can extend the housing segments 5 and 16 axially from the housing base 3 and then fix them in place. A rotary motion can be used for this purpose. The projectile 1 has two fixing areas 13 and 20, which in this embodiment provide a threaded section. A first fixing area 20 is formed between the proximal housing segment 5 and the distal housing segment 16.

[0063] A second fixing area 13 is thus formed between the proximal housing segment 5 and the housing base body 3.

[0064] In other words, a user pulls the housing segments 5, 16 out of the housing base 3 and rotates them relative to the housing base 3 so that the threads on the fixing areas 13, 20 are screwed in and the housing segments 5, 16 are fixed in their axial position. During such a rotational movement, no torque is transmitted to the line 12 because, as previously described, the part of the electrical device 6 that is coupled to the line 12, specifically via the receiving device 8, is firmly connected to the housing base 3 via the coupling with the guide sleeve 9.

[0065] When the housing segments 5, 16 are pulled out of the housing base 3, the engagement elements 11, 18 can be moved axially in the receiving elements 10, 19. However, at all times, it is prevented that a circumferential movement of the housing segments 5, 16 is transmitted to the intermediate sleeve 17 or the part of the electrical device 6 that is coupled to the line 12.

[0066] Should the first floor be removed from the in Fig. 5 shown usage position in the in Fig. Once the housing segments 5 and 16 are returned to their initial position shown in Figure 10, the fixing areas 13 and 20 can be released, in particular by a rotational movement opposite to the rotational movement that fixed them. Here too, the engagement elements 11 and 18, which are received in the receiving elements 10 and 19, prevent circumferential movement of the electrical device 6, in particular the receiving device 8. Once the fixing areas 13 and 20 are released, the housing segments 5 and 16 can be inserted back into the housing body 3. During this process, the engagement elements 11 and 18 move axially within the receiving elements 10 and 19.

[0067] Additionally, the unit 1 has bearing areas 14 and 21 in which the housing segments 5 and 16 are mounted. A first bearing area 14 is formed on the housing body 3 and supports the proximal housing segment 5. A second bearing area 21 is formed on the proximal housing segment 5 and supports the distal housing segment 16. The bearing areas 14 and 21 contain, in particular, sealing and retaining elements 15, such as O-rings, which support the housing segments 5 and 16 and, in particular, prevent unintentional displacement. The sealing and retaining elements 15 are designed such that axial movement of the housing segments 5 and 16 only occurs when force is applied by a user, thus preventing independent displacement of the housing segments 5 and 16.

[0068] The Fig. 16, Fig. Figure 17 shows a third embodiment of the projectile 1, which is basically the same as the second embodiment. Fig. 5-10 corresponds, wherein the guide sleeve 9 is an integral part of the housing base body 3, i.e., the inner surface of the housing base body 3 forms the guide sleeve 9. The remaining description with reference to Fig. 5-10 is entirely based on the third embodiment, which is described in Fig. 16, Fig. 17 is shown, transferable.

[0069] Line 12 can be connected to any type of control unit. Control signals or an electrical power supply to the electrical unit 6 can be transmitted via line 12. In principle, it is therefore possible to transmit all data, electrical signals, power supply, and the like from the housing 2 of the projectile 1 to the distal housing segment 16, in particular to the electrical unit 6. The described configuration allows, for example, a control unit for controlling a main shaped charge device to also be used to control the electrical unit 6. It is also possible to use an external power source, such as the power source of a fire control unit or a launching device. Furthermore, the control unit can be used to perform diagnostics on the electrical unit 6.Another possibility is to transmit sensor values ​​or control signals to or from the electrical device 6.

[0070] The projectile 1 may have disarming mechanisms that disarm the electrical device 6 or the part of the firing device 7. The disarming mechanisms are based, in particular, on at least two physically independent mechanisms.
