Compact multicharged weapon. RU patent 2507463.

FIELD: weapons and ammunition.SUBSTANCE: multicharged weapon includes a barrel, a trigger mechanism, a belt receiver and a cartridge box. The cartridge box is located below the barrel and is displaced relative to the central cross section of input window of the belt receiver. The box is designed with the belt which links provide misalignment of a cartridge in output window of the box and input window of the belt receiver. The box is fixed at an angle to the specified plane of the central cross section of input window of the belt receiver. Angle is equal to admissible misalignment of used type of the belt.EFFECT: decreasing weapon dimensions, improving its qualitative characteristics and ergonomics.6 cl, 6 dwgThe invention relates to the automatic small arms, primarily for the machine guns, and can be used in robotic complexes.Known repeating mechanism weapons, in which the basket with the cartridges located above the barrel and ammunition in the box are tilted and served ago (see Pat. UK GB 191516038 (A) - 1919-03-27).The disadvantage of this device is the limited capacity of the boxes, low reliability due to the high probability of jamming cartridge. In addition, store in a unit weight of the trunk and makes it difficult shooting.Known for M-60 machine gun, containing a barrel, butt, trigger mechanism and a box with a ribbon on the left side of the trunk (Fig 1), however, this mount makes the weapons unstable relative to the axis of the barrel and makes it difficult shooting from the hip.It is also known repeating mechanism weapons containing barrel, butt, trigger mechanism and a box of bullets, located below the barrel outside section of the inlet window and made in a form of a semicircle. This device is the closest to the invention (see GB 127278 (A) - 1919-06-05).The disadvantage of this device is the limited capacity of the boxes, low reliability due to the high probability of jamming cartridge. In addition, store in a unit weight of the trunk and does not allow to balance the weapons in the longitudinal direction, which makes it difficult to use.The technical result expected from the use of the invention, is:

- decrease of overall dimensions at preservation of the barrel length,- increasing the capacity boxes when saving dimensions the height,- the possibility of gunfire standing,- decrease of time of opening fire, able to produce more than a quick shot while shooting «at a glance» at the expense of a close-to-shoulder to the center of mass of weapons that simultaneously improves handling weapons and reduces the time of aiming,- increase of effectiveness of fire from unstable positions,- increase the transfer speed of the fire,- increasing the convenience of work in the constrained conditions (transportation, facilities etc).This goal is achieved by the fact that in the known weapons containing barrel, trigger mechanism and a box of bullets, located below the barrel and the offset relative to the Central cross-section of the input window , basket completed with a ribbon units which provide misalignment cartridge in the outlet boxes and input window , and is fixed at an angle to the specified plane of the Central cross-section of the input window equal to the permissible misalignment of the type of tape.The box may be executed with the possibility to adjust the angle to the plane of the cross-section of the input window .In addition, the box can be mounted in position gained an additional turn a sharp corner around the axis of the trunk and/or perpendicular to that axis, and/or vertical axis of the box.The distance fastening of boxes from the Central cross-section of the input window and the corresponding angle to the specified plane of the Central cross-section of the input window can be selected on the basis of coming as close as possible to the center of gravity of the boxes to the center of gravity of the entire device.In addition, the device can be supplied with tape guides, located between the outlet boxes and input window .The repeating mechanism gun can be completed with electronic stabilization systems, and/or aiming, and/or control for feed, a power supply or batteries which are ACCOMMODATED IN  an additional compartment box, and a connection output power bus and input tyres in the electronic stabilization systems, and aiming performed split.Accommodation boxes below the barrel outside the Central cross-section of the input window means that the projection of the plane boxes in which it has its outlet on the horizontal plane, which is the trunk is displaced along the trunk in the plane with

respect to the transversal axis of the input window . Thus, trunking tape is placed to the side of the input window and is not directly located under it, as in the known solutions and shifted along the trunk with respect to the input window forward or back and tilted relative to the perpendicular to the shaft so that the offset distance trunking when submitting tapes are provided structurally valid for this type of the bending radii and the misalignment of the links in the passage way from the guide trunking to guides on the input window weapons. And at the specified offset and inclined status box is fixed.Execution box with ribbon means that the cartridges are placed on the tape and the tape is Packed in the box with the possibility of submitting outlet.Performing a tape with the possibility of misalignment cartridge in the outlet boxes and input window means that the links are made with the possibility of backlash, or rotate relative to each other, not only about the transversal axis of the tape, which provides its flexibility, in a decision, providing a bend around the short transverse axis or axis of the cartridge, and a summary of its «fan» of the tape plane, but backlash and rotation around «long», the longitudinal axis, so that the cartridge «turns» on some angle in respect to the plane of the tape.Misalignment in relation to this type of tape and selection bias trunking means the sum of the tolerances of the misalignment of the total number of links tape staying in this case between the outlet boxes and input window (taking into account their linear displacement). However, the optimal angle of fastening of boxes within a specified tolerance can be defined as the average of the settlement (geometric) characteristics applied the tape, and by experience - by the criterion of maximum stability and the duration of work in difficult conditions (temperature, pollution etc). And stability in the first place means no jamming and other effects, causing uneven motion of the tape across all modes of use of weapons.Function adjust the angle of the boxes at the desired offset distance means to adapt to the parameters (different types) tape without significant changes in the layout.The location of the projection of the vertical axis of boxes on the plane perpendicular to the axis of the barrel at a sharp angle to the perpendicular to the axis of the barrel (which lies in the specified plane) means that the remaining located below the barrel, trunking rotated about the axis of the last left or right, but also can be rotated simultaneously relative to that of the perpendicular or its own axis. Moreover, for the boxes in the

complex and asymmetrical designs as the axis can be chosen perpendicular to the plane of attachment or other surface, on which is placed outlet to the tape.Figure 2 shows a General view of the proposed device. Figure 3, and 4 illustrate the design of a 7.62-mm machine-gun Kalashnikov PC and the proposed device in the layout of the bullpup» respectively. This is done to demonstrate the usability of the proposed location of the boxes of ammunition exactly in the layout of the bullpup», although it can be used at modernization of machine guns in the normal layout. Figure 5 illustrates the creature proposals for a standard layout.Repeating mechanism weapons contains (figure 3, 4):1. A box with cartridges placed on the ribbon2. Staffing mount boxes3.

Electronic sighting system marked .19. .20 figure 5 marked the setting of the angular position of the fastening of boxes 8 and actually boxes 1. 6 schematically a ribbon item 17 with the links of 21, have the mobility relative to each other, in particular, are likely to rotate around the axis of the 22 and 23.Heirs of machine guns, as is known, became the General purpose machine guns, keep the fire from which you can bipod, ground tripod, and with anti-aircraft, automotive, helicopters and other installations. The proposed change mounting design trunking allows you to apply a layout of the bullpup» on machine guns with belt feeding that in many cases, improves the efficiency of the use of such weapons by 20-30% compared with standard version.Operation of the device we first consider the traditional layout. It is the same as in the famous weapons, but with the difference that due to the shift of boxes 1 of ammunition 18, placed on the

ribbon 17, the value of L in the direction of the outlet trunk 14 and turn about the axis of the control element 20 at angle alpha (or the axis perpendicular to the axis of the barrel 14, see figure 5) cartridges 18 being in the plane tape 17 at exit box 1 tilted sleeve down, and being in the input box 15 (the drawings is not separately allocated as other regular parts of a device), parallel trunk 14 weapons. This is achieved at the expense of flexibility tape 17, links 21 of which have, for example, the ability to shift and rotation around two mutually perpendicular axes 22, 23 (6).The greatest advantages of the proposed technical solutions are disclosed in the layout of the bullpup shown in figure 2, 4. This applies equally to the case of the creation of new products and upgrades.1.
