Description

Detailed Description of the Invention

The present invention relates to ammunition and firearms, and more particularly, the invention relates to shells with a shell, a barrel for firing shells with a shell, and a large number of shells axially stacked within the shell. It relates to a barrel that incorporates a tubular projectile.

A projectile with a shell is used for applications where the projectile is required to have high kinetic energy, for example, for penetrating an armor plate of a battleship or a tank, and for long-distance applications. The shelled projectile generally incorporates a reduced bore projectile adapted with a relatively light shell to provide a gas seal with the barrel bore. Since the shotgun allows the propellant charge to apply propulsion over a larger area, the reduced diameter projectile and the relatively light weight shotgun achieve greater barrel speeds than for full caliber projectiles.

The cartridge is typically separated from the reduced diameter projectile after it exits the barrel muzzle, and in some constructions is adapted to disassemble after it exits the barrel muzzle. .
Other shotgun structures employ various systems for separating the shotgun from the reduced bore projectile. The different centrifugal forces generated by the barrel with a rifle on the shell and the reduced diameter projectile are employed in the design of the shell that separates the shell from the reduced diameter projectile. In other constructions, the aerodynamic resistance of the shotgun to the aerodynamic resistance of the reduced bore projectile may be used to separate the shotgun from the reduced bore projectile.

A barrel having both a plurality of projectiles axially stacked within the barrel and independent, selectively ignitable projectile charge for propelling the projectiles sequentially through the muzzle of the barrel. Can fire projectiles at extremely high speeds. Firing a bullet with such a high velocity increases the likelihood that the projectile will collide with the bullet from the previously fired bullet and become invalid. Applicants have now found a structure that minimizes the likelihood of projectiles colliding with the shell from a previously fired bullet.

Therefore, in one aspect, the present invention provides a barrel that incorporates a number of projectiles with shotguns axially stacked within the barrel and a number of corresponding projectile charges disposed therebetween. Providing a barrel including a barrel having a muzzle, the barrel including a barrel removal structure and a barrel receiver arranged to prevent the barrel from exiting the barrel muzzle. , A plurality of projectiles with shotguns comprising a plurality of projectiles and a plurality of associated projectiles, the associated projectiles being separably engaged with the projectiles such that when the forward projectile charge explodes The projectile with a bullet shell is urged into sealing engagement with the barrel.

In a second aspect, the invention provides a barrel having a muzzle, the barrel comprising:
Included is a shell removal structure and a shell receiver that is arranged to prevent the shell from exiting the muzzle of the barrel.

In a third aspect, the present invention provides a projectile with a shell for axial stacking within a barrel having a projectile and a shell, the shell being separable from the projectile. In combination, the explosion of the forward projectile charge in the axially stacked array urges the trailing projectile with a shell into sealing engagement with the barrel.

The present invention is capable of firing a controlled rapid-fire sequence of projectiles, and PCT / AU94
Barrels of the general type described and / or illustrated in Applicants' prior international patent applications, including / 00124 and PCT / AU96 / 00459, may be employed. However, other barrels may be employed in the present invention that incorporate independent launch charges for propelling each shell-loaded projectile axially stacked within the barrel.

The projectile may be machined into a rounded, normal shape or dart, with its fins offset to provide stability when the arrow is propelled from the barrel, which may be a smooth barrel barrel. Spin rotation may be generated.

Each projectile may include a projectile head and a tail portion for at least partially defining a launch space. The tail portion may include a spacer assembly extending posteriorly from the projectile head and in contact with the proximal projectile assembly.

The spacer assembly may extend through the firing space and the projectile head, whereby compressive loads are directly transmitted through the proximal spacer assembly in contact. In such a structure, the spacer assembly may add support to the expansion means, which may be the thin cylindrical rear portion of the projectile head. Furthermore, the expansion means
A functional sealing contact with the shell bore may be formed to prevent combustion leakage through the projectile head.

[0012] The spacer assembly is capable of transferring axial compressive loads directly between the spacer assemblies, thereby allowing malleable sealing contact with the bore of the shell to avoid deformation of the projectile spacer. A hard collar portion may be included that extends outwardly to engage the thin cylindrical rear portion of the projectile head.

Each projectile has a bullet-shaped head about which the shell is positioned, and a tail portion that extends rearward to contact the leading end of the next adjacent rear projectile, thereby being stacked. The rows of cannonballs are preferably securely positioned in their functional position within the barrel. With this structure, it becomes possible to adopt a large amount of propellant charge for each projectile,
This can provide high kinetic energy to the projectile.

Alternatively, the projectile explosive is formed as a solid block functionally spaced between the projectiles within the shell, or the projectile charge contacts the pre-positioned electrical contacts associated with the shell. It may be housed in a metal or other rigid case containing an embedded detonator with external contact means adapted accordingly. For example, the detonator allows for the insertion of a packaged charge into the shell and is retractable to pop into the opening when aligned with the opening for functional contact with the mating shell contact. It may have a spring contact. If desired, the shell may be disposable or chemically assist in burning the charge.

The shell is in the form of complementary wedge-shaped surfaces respectively arranged on the projectile heads, whereby the projectile heads are arranged relative to each other between the spacer means and the projectile heads. It is biased into engagement with the bore of the barrel in response to axial compression. With such a configuration,
After loading the projectile head and spacer assembly into the barrel, axial displacement may occur to ensure a sufficient seal between the projectile head and barrel. The expansion means is suitably biased to engage the bore of the barrel.

The barrel may be non-metallic and the bore of the barrel may include a recess that fully or partially houses the firing means. In this configuration, the barrel contains a conductor that facilitates electrical conduction between the control means and the firing means. This arrangement may be utilized with a disposable barrel having a firing life limit so that the firing means or control wire or wires may be manufactured integrally with the barrel.

The cartridge may alternatively include a firing opening in the barrel and the firing means may be located outside the barrel and proximate the opening. The barrel may be surrounded by a non-metal external barrel that forms a sleeve that includes a recess adapted to accommodate the firing means. The outer barrel may contain a conductor that facilitates electrical conduction between the control means and the firing means. The outer barrel may be formed as a laminated plastic shell containing a printed circuit laminate of the firing means.

The cartridge may have adjacent projectiles separated from each other and kept axially spaced by positioning means remote from the projectiles, each projectile comprising:
It may include expandable sealing means to form an effective seal with the barrel bore. The positioning means may be a propellant charge between adjacent projectiles and the sealing means suitably includes a skirt portion on each projectile which expands outwardly when subjected to an in-shell load. The in-shell load is applied after loading, such as during loading of the projectile, or by stuffing to arrange the columns of projectile and propellant charge, or external propellant charge, especially,
Occurs when the adjacent external charge is fired.

The projectile includes a metal jacket adapted to be seated and / or located in the circumferential groove, or at the annular rib of the bore, or in the rifling groove of the bore and surrounding at least the outer end of the projectile. But it's okay. The projectile spreads outward in an annular groove in the shell,
A retractable peripheral locating ring may be provided that retracts into the projectile during firing to allow free passage through the barrel.

The electric ignition device for sequentially igniting the propellant charges of the barrel portion ignites the forward propellant charge by sending an ignition signal through the stacked projectiles, and then the forward propellant charge is ignited. Preferably, the step of preparing the next propellant charge for activation by the firing signal is ready for firing.

The firing of the propellant charge may be performed electrically, or the firing may be performed by firing an outermost projectile and controlling the resulting firing to sequentially fire the propellant charge for the next shot. Conventional firing pin methods may be employed, such as by using a central detonator. This may be done by controlling the back-leakage of combustion gases or by controlling the combustion of fuze rows extending through the projectile.

In another form, firing is electronically controlled with a respective propellant charge associated with a detonator that detonates with a unique firing signal. For example, the detonators in the stacked propellant charge may be arranged in sequence to increase the pulse width firing condition, whereby electronic control selectively sends a pulse width increasing firing signal to sequentially sequence in a selected time sequence. Ignite the propellant charge. However, it is preferred that the propellant charge fires at the set pulse width signal and the combustion of the forward propellant charge prepares the next propellant charge for firing with the next firing pulse.

Suitably in such an embodiment, all propellant charge from the end to the inside of the loaded barrel is secured by the insertion of respective insulated fuzes located between the normally closed electrical contacts, The fuzes are set so that they can burn and close the contact upon transmission of the appropriate firing signal, with each insulated fuze being open to its respective forward firing charge for ignition.

Any conventional trigger may be used in the present invention. A conventional trigger mechanism may be used. In such a conventional trigger mechanism, a single firing event is
It may be squeezing or holding the trigger only once for a given number of projectiles to be fired. As with automatic weapons such as machine guns in automatic mode, it is not necessary to hold the trigger held down while firing a predetermined number of projectiles. Other triggering mechanisms may be employed as long as a single firing event initiated directly or remotely by the user can activate the trigger and fire a predetermined number of bullets.

The projectile and associated shells are preferably configured to impede forward movement relative to the projectile so that the shell is accelerated integrally with the projectile through the barrel towards the muzzle. It Preferably, the shell is separably engaged with the projectile, thereby securing it against forward movement relative to the projectile. The cartridge may be separably secured to the projectile by tabs for engaging the projectile into, for example, corresponding recesses. Alternatively, the projectile may incorporate tabs for engaging the cartridge, for example within corresponding recesses in the cartridge. Preferably, the separable engagement of the cartridge with the projectile does not constrain its relative rearward movement along the projectile for removal purposes, so that the projectile has no impact from the projectile. Not much slowed down when removed.

In one embodiment, complementary shallow inwardly directed annular ribs on the inner surface of the shell are located within the shallow outer annular recess within the projectile and are disengaged by the removal structure. . Alternatively, an annular recess in the inner surface of the cartridge may be located around the complementary convex outer annular portion of the projectile that is disengaged by the removal structure. In another form, an interference fit, preferably a tapered interference fit between the projectile and the shell provides a separable engagement between the shell and the projectile, which is removed. It is moved during forward movement of the projectile relative to the shell, as occurs by construction.

In a preferred embodiment, each cartridge is engaged via an inversely tapered land portion such that the outer annular portion radially expands upon initiation of movement of the inner annular portion therethrough. It comprises a pair of complementary continuous or split annular portions which are biased into sealing engagement with the barrel. The inner annulus is biased to move through the outer annulus by the detonation of the propellant charge in front of the shelled projectile in the axially stacked array of projectiles. A laterally extending flange may be provided on one of the annular portions to limit relative axial movement of the inner annular portion via the outer annular portion. In one form, preferably the flange is a radially outwardly extending flange formed at the rear end of the inner annular portion.

[0028] The barrel portion includes a barrel, the barrel having an arrangement for removing a shell and a shell receiver to prevent the shell from exiting the muzzle of the barrel.

[0029] Preferably, the shell removal structure includes an inner sleeve disposed concentric with the barrel at or near the muzzle, through which the projectile passes and around which the shell passes. To do. The sleeve may be appropriately tapered at its removal end to bias the barrel against the annular barrel portion between the sleeve and the muzzle of the barrel.

In a preferred form, the barrel comprises a gun proximate the removal end of the sleeve to accommodate the cartridge removed from the projectile with the cartridge without substantially compressing the removed cartridge without radial compression. Open outwards at mouth. The inner sleeve portion may be supported by a web extending between the sleeve and the open portion of the barrel, between which the removed shell is passed.

The removed cartridge may pass within the annular barrel portion proximate the sleeve.
The removed shell is preferably retained in an annular storage at the muzzle end of the barrel so as to prevent its possible collision with subsequent ones of the rapidly fired projectiles. The removed cartridge may be adapted to be removed from the barrel through a side opening proximate the muzzle.

Braking of the removed cartridge in the barrel provides a reaction that serves to reduce the counteracting of the barrel. This reaction is also accomplished by forcing the shell to radially compress during passage through the annular passage.

[0033]   In order to more easily understand and implement the present invention, reference is made to the accompanying drawings.

The multi-barrel firearm 10 comprises a cluster of barrels 11 each supporting a plurality of shells 12 each stacked axially within each barrel 11.

Each shell comprises a projectile head 13 supported within the respective barrel by a shell assembly 14. The tail portion 15 extends rearward so as to be in contact with the nose portion of the trailing projectile 12. For this reason, the rear end of the rear stem 15 is
It has a recess that fits snugly at the front end of 3.

The projectile ammunition 16 extends around the aft stem 15 and acts on any laterally extending surfaces of the shell 14 and the respective projectile when electrically or otherwise ignited. To propel the projectile along with their shell 14 through the barrel toward the muzzle end 20 of the barrel 10.

Each barrel 12 opens outward toward the muzzle from a point proximate the inner end 22 of a concentric removal sleeve 23 supported by an end wall 25 in its respective open end section.

The bore diameter of the sleeve 23 is substantially the same as the outer diameter of the projectile head 13 so that the projectile head passes directly through it and exits the barrel 10 at high speed.

Since the sleeves 23 taper towards their rear ends and present a relatively fine annular end for approaching shells, they are between the shell 14 and the projectile head 13. The shell 14 can be removed from the projectile head 13 as it engages and the projectile head 13 passes through the sleeve 23. The shell 14 is deflected by its radial expansion around the sleeve 13 or becomes a segmented segment and collects in an annular passage 28 which extends around the sleeve 23.

This action changes the orientation of the shell section around the sleeve so that it may impact the shell 14 by collision with the end wall 25 or another shell already located in the passage 28. Decelerate, then stop.

This action may be accompanied by a rapid deceleration just before the impact as the gas is compressed between the front end of the shell and the end wall 25. The resulting gradual deceleration of the shell 14 serves to reduce the recoil resulting from the firing of the respective propellant charge.

Each cartridge 14 is connected to the projectile head 1 via complementary engagement serrations 29.
3 has an inner annulus 30 that engages 3 and an associated outer annulus 31 that mates with the inner annulus 30 along a forwardly tapered surface 33 so that the acceleration of the shell through the barrel 11 is The outer annulus 31 is pushed back along the inner annulus 30 resulting in a radial expansion that biases the shell 14 into an effective seal with the barrel 11. .

The circular flange 32 extends from the rear surface of the inner annular portion 30 to the outer annular portion 31 and / or substantially to the barrel 11, behind which the reaction surface 35 with which the combustion products of the propellant charge can react. Provides a limit of movement.

From the above description, the beneficial effect of a cartridge that allows the use of larger amounts of propellant charge, without the occurrence of scrap of the cartridge causing local impact, It can be seen that this can be achieved without causing the scrap of the aerial shell that becomes a collision obstacle of the fired projectile.

The above description illustrates the present invention by way of example only, and all modifications and variations thereto that will be apparent to those skilled in the art are obvious to the invention as set forth herein. It should, of course, be understood that it is not considered out of scope.
