Description
A Counter Measure Cartridge
Field of the Invention
The invention relates to air counter measure cartridges and in particular to multi-shot counter measure cartridges.
Background to the Invention
The closest prior art known to the applicant is the applicant's own prior patent application GB 1007859.0. The invention concerns a countermeasure cartridge to overcome the following drawbacks of the prior art countermeasure cartridges: * Assembly of known cartridges are complicated and manually intensive, such as screwing the components together with multiple screws; * Complicated potting and gluing procedures are required for known cartridges, which increases the time required for assembling the device; * A film / wire conductor to squib housing, which can lead to problems with the quality of known cartridge; * The assembly of known cartridges requires numerous packing pieces to fill any resulting voids within the cartridge; * The assembly of known take-over cup assemblies require additional take-over assemblies; and Whole cartridges require an X-ray inspection to confirm no solder inclusions or twisted film wires.
Furthermore, the film / wire is designed to tear, to allow the squib to be ejected along with the payload from the known cartridge. This ensures that the firing circuit is broken within the countermeasure payload before the dispenser interrogates the post-firing resistance of the firing circuit. When assembling the flare, the operator has to partially cut through the film wire to create "weak" points that facilitate in the tearing of the film / wire, when the countermeasure payload is ejected, which can lead to problems with the quality of the known cartridge.
Summary of the Invention
In first broad independent aspect the invention provides a method of assembling a countermeasure cartridge incorporating a plurality of payload container assemblies comprising the steps of: Attaching an electrical conductor to one end of a first payload container assembly wherein the opposite end of said conductor is attached to a first electrical contact means at the opposite end of said first payload container assembly; Inserting said first payload container assembly into an outer case assembly of said cartridge; Rotating said first payload container in relation to said outer case assembly, whereby a first locating protrusion from said first payload container assembly cooperates with a recess / orifice disposed within said outer case assembly and facilitates the alignment of said electrical contact protrusion from said first payload container assembly with a second electrical contact means disposed within said outer case assembly; Inserting a second payload container assembly into said outer case of said cartridge; Rotating said second payload container assembly in relation to said outer case assembly, whereby a second locating protrusion from said second payload container assembly cooperates with a second recess / orifice disposed at one end of said first payload container assembly and facilitates the alignment of a second electrical contact protrusion from said second payload container assembly with said first electrical contact means of said first payload container assembly.
This method provides a fast and efficient means of assembling a multi-shot countermeasure cartridge from independent payload container assemblies. It allows a relatively low skilled operator to repeatedly assemble countermeasure cartridge in which the payload contacts are reliably aligned with the contacts of the outer case, with out any complicated assembly procedure, therefore ensuring that the firing signal is reliably communicated through the cartridge case to the squib device. Furthermore, the method provides a means of stacking the payload countermeasure assemblies within an outer case, while maintaining electrical continuity from the outer case assembly to each payload countermeasure assembly without incorporating any complicated assembly procedures.
Preferably, further comprising the step of disposing a first annular bonding member about a first payload container assembly. The first annular bonding member ensures that both the outer case of the cartridge and the first payload container are maintained at the same potential difference. Therefore preventing any potential difference between the sub-assemblies of the cartridge, which may unintentionally activate the squib device within the first payload. The annular bonding member may be typically in the form of a conductive clip.
Preferably, further comprising the step of disposing a second annular bonding member about a second payload container assembly. The second annular bonding member ensures that both the outer case of the cartridge and the second payload container are maintained at the same potential difference. Therefore preventing any potential difference between the sub-assemblies of the cartridge, which may unintentionally activate the squib within the second payload. The annular bonding member may be typically in the form of a conductive clip.
Preferably, further comprising the step of crimping said outer case assembly to said first and second payload containers via said first and second bonding members. This ensures that the first and second payload counters are retained within the outer case, whilst also remaining bonded to the outer case. Furthermore, once the first payload container has been dispensed from the cartridge, the second payload container is retained within the lower portion of the cartridge without any movement.
Preferably, further comprising the step of disposing said electrical conductor adjacent the outer surface of said first payload container assembly. This prevents any direct contact between the electrical conductor and the countermeasure payload within the container, therefore preventing any unintentional electrical activation of the countermeasure payload.
Preferably, further comprising the step of disposing said electrical conductor in a recess within the outer surface of said first payload container beneath an annular bonding member and / or annular sealing member of said first payload container assembly. This provides a means of routing the electrical firing signals to the contacts on top of the container, without interfering with either of the bonding or sealing members, which may cause possible damage to the electrical conductor and / or cartridge.
Preferably, further comprising the step of disposing said opposite end of the electrical conductor on to the closed end of said first payload container and attaching said opposite of end of said electrical conductor to said first electrical contact means. This provides a means of routing the electrical firing signals to the contacts on top of the container, in a compact and space efficient manner, which do not interfere with the second payload container assembly.
In a second broad independent aspect the invention provides a countermeasure container assembly adapted for use in a countermeasure cartridge, comprising a first electrical contact means and a protruding member disposed at one end of said countermeasure container assembly, which in use, cooperates with a recess / orifice disposed within the outer case assembly; wherein said protruding member facilitates the alignment of said first electrical contact means with an electrical contact means disposed within said outer case assembly.
This configuration provides a quick and simple means stacking two countermeasure container assemblies together, whereby the electrical contact of both container assemblies are aligned with each other via rotating the second countermeasure container assembly in relation the first countermeasure assembly without incurring any complicated assembly procedures. Therefore, communicating a firing pulse to the second countermeasure assembly, which is independent from the first countermeasure assembly.
Preferably, further comprising a second electrical contact means disposed at the opposite end of said countermeasure container in relation to said first electrical contact means.
This provides the means of communicating the firing pulse signal to the squib located within a second countermeasure container assembly, via the countermeasure container assembly.
Preferably, further comprising a recess portion for accommodating said second electrical contact means. This prevents the locating spigots from the countermeasure container assembly from interfering with the electrical conductor and possibly causing damage to the electrical conductor, whilst the second countermeasure container assembly is rotated upon the first payload container.
Preferably, further comprises an electrical conductor which is attached at one end to said first electrical attachment means and opposite end of said conductor is attached to said second electrical attachment means; whereby said conductor is adjacent the outer surface of said countermeasure container assembly. This prevents any direct contact between the electrical conductor and the countermeasure payload within the container, therefore preventing any unintentional electrical activation of the countermeasure payload.
Preferably, said electrical conductor is disposed in a recess within the outer surface of countermeasure container beneath an annular bonding member and / or annular sealing member of said countermeasure container assembly. This provides a means of routing the electrical firing signals to the contacts on top of the container, whilst not interfering with either of the bonding or sealing members, which may cause possible damage to the electrical conductor and / or cartridge.
Preferably, a countermeasure cartridge comprising a countermeasure container.
Preferably, a countermeasure cartridge comprising a plurality of countermeasure cartridges.
Preferably a kit of parts comprising a countermeasure cartridge further comprising: An outer case; a first shutter plate assembly; a first cylindrical body member incorporating a spanning outer electrical, which connected to a set of upper electrical contacts; a first environmental seal; a first bonding seal element; a first nose supporting ring for the pellet payload; a second shutter plate assembly; a second cylindrical body member; an end cap; a second environmental seal; a second bonding seal element; a second nose supporting ring for the pellet payload; and two sets of rear supporting rings. This provides a means in which the countermeasure cartridge may be supplied and assembled as a kit, by an end user / supplier who has the option of inserting countermeasure payload pellets that are independent from the kit. For example the end user may wish to utilise countermeasure payloads, which are only available from themselves. The end user also has the option of supplying the squib device sub-assemblies, which are independent from the kit.
Furthermore, having all the active pyrotechnic devices removed from the kit, enables the kit to be shipped and supplied without any of the costly handling and logistic requirements, which are associated with pyrotechnic devices.
Brief Description of the Figures
Figures 1 shows an exploded view of the counter measure cartridge and associated sub-assemblies.
Detailed Description of the Figures
Figure 1 shows a multi-shot countermeasure cartridge generally indicated by 1. The countermeasure cartridge 1 incorporates an elongate cylindrical outer case 2, which has a flanged edge portion 4 located at one end. An external interface circuit board 3 is crimped within the flange portion 4, via a crimping means (not shown).
A circular seal plate assembly 5 is attached to the outer case via a snap-fitting means (not shown). The seal plate assembLy 5 incorporates an outer channel 6 within its outer surface edge for locating an "0" ring seal (not shown), which abuts both the seal plate assembly 5 and inner surface of the outer case 2. The seal plate assembly 5 incorporates a locating key portion 7, which protrudes from the bottom surface of the seal plate assembly 5. The key 7 co-operates with a keyway 9 which is formed within an internal interface circuit board 10. The key 7 and keyway 9 ensure that the electrical contacts 15 on the internal interface circuit board 10 are aligned with the electrical contact pins (not shown) from the shutter assembLy 11. The seat pLate assembLy 5 incorporates an array of three holes/recesses 12, which cooperate with an array of three protrusions 13 that protrude from the shutter plate assembly 11. The array of protrusions 13 are typically in the form of locating spigots. The internal interface circuit board 10 is attached to the seal plate assembly 11 via a sticky pad which has upper and lower self adhesive surfaces (not shown).
Both the array of holes/recesses 12 within the seal plate assembly S and the cooperating array of protrusions 13 from the shutter plate assembly 1 1, incorporate a spacing of 100 degrees between the first and second recesses, the spacing between the second and third recesses is 120 degrees and the spacing between the third and first recesses is 140 degrees.
The seal plate assembly 5 incorporates a central aperture 14 which enables the routing of one or more electrical conductors, from the external interface circuit board 3, to the internal interface circuit board 10. The aperture also cooperates with the snap-fitting means (not shown) of the internal interface circuit board 10. The spacing configurations of the first, second and third recesses of the seal plate may incorporate alternative spacing configurations, by varying the angular degree spacing between two recesses. The angular degree spacing is relative to the centre of the seal plate / shutter plate assemblies. The spacing configurations distinguish payloads of different configuration types, which enable the assembly of the correct payload types into the countermeasure cartridge 1. The first payload container assemb'y 16 (shown fully assembled) incorporates a cylindrical body member 17, which is closed at one end 18 and is open at the opposite end. The shutter plate assembly ills located at the open end of the cylindrical body member 1 7. The closed end 18 of the cylindrical body member 17 incorporates a second array of three holes / recesses 19, which has the same spacings as the first array of hole/recesses 12 within the seal plate assembly 5. The closed end 18 of the cylindrical body member 17 incorporates a recess 20 within the cylindrical body's outer edge. Two electrical conductors 22 are located beneath a metallic, annular bonding clip 26 and an ring environmental seal 27, both of which are located on the outer surface of the cylindrical body member 17, within close proximity of its closed end 18, and are attached via a mechanical pinning means 21.
The electrical conductors are typically of a film wire type, such as a ribbon type cable(s), insulated foil type cable(s) or flexible Printed Circuit Boards (PCB5) or the like. Each electrical conductor 22 incorporates, or is attached to, an electrical contact portion 23.
Each electrical contact portion 23 is positioned to align with the electrical contact pins (not shown) of the shutter ptate assembLy 37 of the second payLoad container assembLy 25.
The second payload container assembly 25 (shown in an exploded view) is very similar to the first payload container assembly 16 and incorporates a shutter plate assembly 37, a leaf member 24, an "0" ring packing piece 28, a countermeasure payload pellet 29, a cylindrical body member 30, an annular metallic bonding clip 31 and an "0" ring environmental seal 32. Furthermore, an array of three holes / recesses 33 located on the closed end 34 of the cylindrical body member 30, which has the same spacings as the first and second array of three holes / recesses 12 and 19. The leaf member 24 is attached to the shutter plate assembly 37, via a snap fitting means, which cooperates with a cavity within the shutter plate assembly 37.
The two payload assemblies 16 and 25 have substantially similar diameters, which enable them to be stacked in a tandem configuration within the outer case 2 The components of each payload assembly 16 and 25 have substantially similar diameters, which provides each payload 16 and 25 with an overall cylindrical appearance.
An end cap 35, which is typically formed from a plastics material is attached to the array of three holes / recesses 33, via an array of three locating protrusions 36, which protrude from the under side of the end cap 35.
The closed ends 18 and 34 and cylindrical body members 17 and 30, of each of the first and second payload containers 16 and 25 are formed from a single portion of metallic material, such as an aluminium or aluminium based alloy.
In use, the first and second payload container assemblies are loaded into the outer case of the countermeasure cartridge. The first payload container assembly is rotated in relation to the outer case so that its locating protrusions are aligned with the holes / recesses within the seal plate assembly, which is incorporated within the outer case. This ensures that the electrical contacts of the internal interface circuit board are aligned with the electrical contacts of the first payload container assembly. The second payload container assembly is rotated in relation to the outer case so that its locating protrusions are aligned with the locating holes / recesses, which are incorporated within the top of the first payload container assembly. This ensures that the electrical contacts on top of the first payload container assembly are aligned with the electrical contacts of the second payload container assemble, therefore, providing electrical continuity between the external interface circuit board and both the first and second payload container assemblies.
An electrical firing pulse is applied to the external interface PCB, which is then communicated to the internal circuit board. For a two shot countermeasure cartridge, the two payloads assemblies share a common 0 Volt (OV) electrical contact, which is centrally located on the external interface circuit board. There are also three concentric electrical contact rings, which are spaced from the central OV electrical contact that communicate both the firing pulses and conventional inventory sensing pulses to each payload assembly.
When a firing pulse is communicated to the countermeasure cartridge, a subsequent first firing pulse is communicated to the first payload assembly after an initial time delay has expired. A second subsequent firing pulse is communicated to the second payload assembly after a second short time delay has lapsed, which is subsequent to the first firing pulse. The firing pulse to the first payload assembly may be typically routed from the concentric electrical contact ring which is adjacent the central OV electrical contact. The firing pulse to the second payload assembly may be typically routed from either of the next two adjacent electrical contact rings, which are dedicated for use in communicating the inventory sensing pulses to each of the payload assemblies.
The electrical firing pulse is communicated from the external interface circuit board via one or more electrical conductors, which are located within the outer case and routed through the seal plate assembly's central aperture, and then subsequently connected to the internal interface circuit board.
The internal interface circuit board then routes the firing pulses to either the first payload assembly, or the second payload assembly via dedicated electrical contacts. One set of electrical contacts routes the firing pulse to the first / upper payload container assembly.
Another set of electrical contacts routes the firing pulse to the second / lower payload container assembly.
If the firing pulse is intended to be routed to the first / upper payload container assembly, it is communicated to a second electrical conductor, which bypasses the first / upper paytoad container assembly. The second conductor then communicates the firing puLse to a second set of electrical contacts, which are located on top of the second / lower payload container assembly. The second set of electrical contacts then subsequently communicates the firing pulse to electrical contact pins protruding from the second shutter plate assembly, which is incorporated within the first I upper payload container assembly. The firing pulse will initiate the squib device incorporated within the second shutter plate assembly, which in turn initiates the first / upper payload container assembly.
The whole of the first / upper payload container assembly is jettisoned from the countermeasure cartridge, therefore leaving no obstruction to the second / lower payload container assembly. Furthermore, since the first / upper payload container assembly has been removed, there is no possibility of any subsequent inventory sensing pulses detecting the presence of the first / upper payload container assembly. However if its presence is detected after the application of the firing pulse, a miss fire is recorded for the payload container assembly.
If the firing pulse is intended to be routed second / lower payload container assembly, it is communicated to the electrical contact pins protruding from the first shutter plate assembly, which is incorporated within second / lower payload container assembly. The firing pulse will initiate the squib device incorporated within the shutter plate assembly, which in turn initiates the second / lower payload container assembly. The whole of the second / lower payload container assembly is jettisoned from the countermeasure cartridge. However, if the first I upper payload container assembly was still present within the cartridge, it would also be jettisoned along with the second / lower payload container assembly, therefore clearing the cartridge of any misfired payloads.
Furthermore, a multi-shot countermeasure cartridge will require one or more electrical contacts, located on the external interface circuit board, to allow a second payload to be fired. Therefore, one or more additional electrical contacts are required on the internal interface circuit board, to align with an additional contact pin within the contact block of the shutter plate assembly. The electrical conductor (such as a film wire) may be soldered to the backs of two of the three pins in the contact block.
The two firing/return pads on the flexible electrical conductors will be positioned to allow use of the standard two pin Typhoon type payloads (but shortened).
In alternative embodiment of the invention, it is intended that the countermeasure cartridge may be supplied as a kit, which is assembled by personnel that have no specialist assembly skills in assembling conventional countermeasure cartridges. Or alternatively, the cartridge may be supplied as a fully assembled unit.
The kit consists of: An outer case (fully assembled with a seal plate and PCB boards); A first shutter plate assembly (not including the squib device sub-assembly); A first cylindrical body member incorporating a spanning outer electrical, which connected to a set of upper electrical contacts; A first environmental seal; A first bonding seal element; A first nose supporting ring for the pellet payload A second shutter plate assembly (not including the squib device sub-assembly); A second cylindrical body member; An end cap; A second environmental seal; A second bonding seal element; A second nose supporting ring for the pellet payload; and Two sets of rear supporting rings (typically four rings of various thicknesses, such as 1.5mm, 2.5mm, 3.5mm and 4.5mm).
It is also the intention to include some variability on the configuration of the kits, therefore the kits may be supplied with the pyrotechnic sub-assembly and/or with a pellet countermeasure payload but this depends on the safety criteria of the user as these are all classed as pyrotechnic devices and warrant extreme safety measures.
The advantages in summary of the invention are:
It substantially reduces the time for producing a countermeasure cartridge and its associated payloads; It offers flexibility in configuring the cartridge to a new configuration by the interchanging of the pellet containers to separate, independent countermeasure payloads. Therefore, providing a countermeasure with different countermeasure payloads, which may be more effective against known missile threats.
It provides a means of cleanly jettisoning a countermeasure payload, which does not have any of the inherent problems associated with other multi-shot solutions that detect the presence of dispensed countermeasure payloads due to inventory sensing pulses detecting high resistance across the connecting electrical conductors.
It could be fully assembled quickly and easily using snap fitting methods of assembly which incorporates no potting or any other processes which take a long time to cure; and Depending upon the capacity of the countermeasure cartridge and countermeasure system, the countermeasure cartridge may configured into a number of optional multi-shot combinations, such as incorporating four or more countermeasure payloads.
Therefore, the time and materials required to produce this device makes it an efficient, cost effective solution, which is easy to manufacture and does not require especially skilled operatives to carry out the task of assembly.
