AND PROJECTILES MADE ACCORDING TO THE METHOD, AND METHOD FOR UTILIZING THEIR SPECIAL CHARACTERISTICS IMPARTED BY THE METHOD FOR MANUFACTURE WHEN FIRING THESE PROJECTILES}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for producing a ballistic missile, which is mainly equipped with a metal shell made of copper and is intended to be fired from a wire barrel such as a gun, an anti-tank gun and an anti-aircraft gun such as a combat vehicle.

The invention also relates to a bombardment projectile intended to implement the method according to the invention.

The special feature of the shell-type projectiles produced in accordance with the present invention is that the projectiles can be switched as needed so that the projectiles leave from the wire barrel firing the projectiles with or without rotating inherently. Can be given as a result. The invention is intended to be fired from a wire barrel and in one simple operation between two different modes or in two functional variants (depending on one variant the projectile leaves the barrel without rotation, in the second variant Means a projectile manufactured according to the above method, which can be switched between the barrel and the barrel used, typically leaving the barrel while rotating. In addition, the method according to the invention can be used to produce a steel barrel barrel projectile without the above switching function, so that the projectile is manufactured to leave the barrel without or rotating from the outset.

Standard full-caliber projectiles fired from steel barreled guns are usually rotationally stable. The term "rotationally stable" is intended to mean that the projectile is stabilized in the trajectory toward the target by causing the projectile to rotate about its own longitudinal axis. In many cases, however, it is necessary to fire some special projectile without rotation from the same liner barrel that is most preferably used to fire a conventional rotationally stable projectile. Projectiles to be fired without rotation consist primarily of long range, wing stabilized standard aperture guided projectiles and likewise wing stabilized and sub-caliber solid core projectiles. Since projectiles that need to be fired without such rotation can often be fired in concert with other projectiles that need to be stabilized by rotation, there is no practical solution to the problem other than changing the barrel between projectile types. Do not.

Conventional rotationally stabilized projectiles fired from steel wire barrels obtain rotation through the interaction between a magazine made of soft metal, usually copper, and the land of the barrel steel wire. The carriage must be fixed against the torsion and immovably coupled to the projectile so that the rotation of the platform imposed by the barrel liner can be transmitted completely to the projectile. Therefore, in the conventional method for manufacturing a metal bullet shell projectile, until now, the annular shell is prefabricated with an inner opening diameter that can be fitted onto the projectile, and the annular shell is likewise applied to the projectile. Pressing into the prefabricated grooves by high pressure meant reducing the inside and outside diameters of the shot. In order to make large diameter shells, great pressure was required, which naturally increases the manufacturing cost.

An important object of the present invention is to provide a ballistic projectile intended to be fired from a liner barrel, at least substantially reducing and preferably eliminating the problems described above, so that the beneficial features of the ballistic projectile can be used more effectively than ever before. It is to provide an improved method for manufacturing.

The stated object and other objects not listed in this specification are satisfactorily achieved within the scope of the specification contained in the independent claims of the present invention. Embodiments of the invention are specified in the dependent claims.

Accordingly, the present invention provides a bombardment projectile intended to be fired from a liner barrel, characterized in that the basically annular shell of the projectile is coupled to the projectile body by a female screw and a male thread correspondingly applied along the outside of the projectile body. Provided is an improved method for manufacturing.

Another aspect of the method according to the invention is as follows.

When the firing of the projectile is intended to be rotationally stabilized, the platform is fixed relative to the projectile body in the rear stop position in the firing direction of the projectile after screwing into the projectile body but before firing.

When firing one and the same type of bullet type projectile from a liner barrel, a choice is made between the full non-rotational firing of the projectile and the rotational launch of the projectile corresponding to the barrel liner, the projectile shell having the corresponding male thread of the projectile body. A non-rotating shot, the bullet mount being fitted as far forward as possible in the direction of the launch of the projectile on the male thread of the projectile body, the male thread being at least at least in the same manner as the spiral and barrel strands of the barrel steel wire; It is formed with the same number of spiral turns so that when full rotation of the projectile is required, the opportunity for the bullet to rotate is prevented before launch.

When full rotational firing of the projectile is required, before the launch of the projectile, the shell is tightened along the male thread of the projectile body to the rearward stop position in the projectile's intended firing direction, so that the rotation the barrel barrel gives to the projectile is Ensuring complete delivery prevents the opportunity for the bullet to rotate.

When rotating the projectile fired with the aid of a bullet-mounted release barrel, it is ensured that each escaped barrel is completely free from each shell when the exit barrel leaves the barrel, and a male screw is provided in the exit barrel. Each shell provided with a female thread is screwed into the leading position of each male thread in the intended firing direction of the projectile, and these screws are formed with a thread winding number somewhat less than that of the barrel wire.

A bullet type standard caliber projectile is manufactured, which can be fired from the steel barrel by rotating the barrel of the barrel used for firing or with no rotation at all, and the projectile is made in the form of two projectile components that can be screwed together. Wherein the first projectile component has a coupling portion provided with a male screw, the coupling portion configured to be inserted into a corresponding cavity of a second projectile component provided with a corresponding female thread, and the first or second projectile component is configured to be such a projectile component. Adjacent to the engaging portion there is a rotationally reduced screw section that is screwed to the female threaded carriage, where the screw is screwed before the projectile component is screwed together.

Furthermore, in the present invention, a ballistic projectile intended to implement the method according to the present invention is connected to the projectile by means of its female thread and a male screw correspondingly arranged along the outside of the projectile, the screws interacting with each other. Characterized in that.

According to another aspect of a bombardment projectile intended to implement the method according to the invention is as follows.

The projectiles can be fired either by a barrel wire or with no rotation at all, each projectile comprising male threads, on which are threaded, essentially annular bullets, essentially including corresponding female threads, All have spirals in the same direction as the barrel wire, and the screw pitch and the thread length of the male thread of the projectile are such that the corresponding shell provided with the female thread is displaced from the front position in the projecting direction of the projectile to the rear position of the projecting direction of the projectile. The exercise is selected to occur over at least the same number of spiral turns as the number of turns of the barrel liner over the entire length of the liner barrel.

When the ballistic projectile is intended to be fired with no rotation from the wire barrel, the projectile consists of a sub-caliber armored iron projectile, which is wing stabilized on the ballistic to the target, the projectile being It is fired with the aid of a breakaway barrel, which has a male thread, on which the screw with the interlocking female thread is screwed, and the male thread of the breakout barrel is shot when the projectile leaves the steel barrel. The path is made to ensure that the platform leaves the exit barrel.

The projectile's shell provides a bursting line that ensures that the platform is destroyed in various parts when the platform is moved by the screw of the leaving barrel and leaves the leaving barrel.

According to the invention, the platform is, in its basic configuration, instead of being pressed into the groove of the shell projectile, instead of being engaged into the projectile by screwing the platform into the projectile body. Since each shell type projectile must normally have the same diameter as the front of the shell, and the rear of the shell, in the method according to the invention, screwing the shell to the projectile body at the same time involves reducing the diameter of the shell. The method according to the invention means that a shell-shaped projectile with a screwed metal shell is usually produced in the form of at least two parts joined together. According to this variant of the invention, one of these two parts is rotationally reduced and screwed with respect to the inner part where the bullet is screwed into and the outer part which is screwed into a recess similarly screwed to the outer part of the projectile. It is formed into joined end sections. In the case of a ballistic projectile manufactured in the manner outlined above, a screw in a recessed groove is defined by the end edge of the rotation reduction towards one end of the projectile and by the end edge of the other projectile component towards the other end of the projectile. The combined shell will be located.

In the specific case discussed in more detail below, a so-called breakout barrel is banded to a standard aperture hardcore projectile.

Thus, in its simplest form, the present invention includes a method of securing a female thread forming band on a shell projectile by a male thread disposed on the shell projectile, instead of pressing the platform into a groove in the projectile. This new method has several advantages.

Thus, in its basic form, the present invention means that the high pressure compression of the bandage no longer exists, thus making manufacturing costs less. this is. In spite of the fact that the method according to the invention essentially involves the manufacture of a shell from two parts joined together. In fact, these two shell parts can be easily manufactured on the same automatic machine used earlier to make the shell into one part. In addition, according to another development of the invention, it is possible, according to the same basic principle, to manufacture shell-type projectiles which can alternatively be fired from the steel wire barrel with or without rotation, while in accordance with the new method, As is apparent from the above, it is also possible to fire a non-rotating projectile from the liner barrel without the use of so-called sleeping plastic shells with many disadvantages.

If it is intended to launch a wing stabilized projectile from the liner barrel without causing the barrel liner to cause the projectile to rotate, it is necessary to use a projectile having a so-called sleeping shell in the prior art. Originally, in projectiles intended for non-rotating firing, the sleeping platform which replaces the copper platform of the conventional rotationally stable projectile has approximately the same shape as the copper platform, but the sleeping platform is made of polyacetal or other plastic material. However, sleeping pads have become very widespread in use, but they are not the ideal solution to the problem. Sleeping plastic bands, for example, do not provide the same effect of sealing against the inner liner of the liner barrel and copper strips without slipping and thus tend to reduce the muzzle velocity V _o of the projectile, and also with so-called "blow-by" by ”is not uncommon, which means that a significant amount of propellant gas leaks out in front of the shell and damages the front of the projectile, which can cause serious problems in the case of so-called" intelligent ammunition ". have. Other disadvantages of so-called sleeping bands include the fact that they are always very sensitive to external damage up to the point of launch, since these bands must be made of relatively soft material. In addition, it is very difficult to construct sleeping plastic bands with suitable sleeping properties. Thus, testing new types of projectiles with sleeping shells is always known to be very expensive. Finally, the sleeping shells are difficult to fit in that they easily get permanent deformation when they are fitted, which means that the fittings usually close the closed band ring over the guide bead of the standard aperture shell or breakaway barrel in the case of barn caliber, solid core projectiles. It involves pressure.

The present invention provides a solution to the above-mentioned problem, which means that it will also be possible in the future to use metal shells, such as copper shells, when firing a non-rotating projectile from the wire barrel. In addition, the present invention, if the final stage without any actual transition to the point immediately before the launch, leaves the wire barrel as a non-rotating projectile in the first variant or mode, and includes the necessary control functions from the starting point, After shedding the stabilizing vanes, it can be further guided towards the intended target, from one to the other, in another variant, without a constituent vane having a profile allowing separation when fired from the same liner barrel, It will be possible to adapt the same projectile up to functioning as a rotating projectile. Thus, the latter variant is suitable for short distances, for example, in which wings are not shed and it is not possible to use the control function. Thus, the present invention makes it possible to use the same shell type for two different types of targets, each of which previously required a different type of shell.

Rotating, wing-stabilized shell-shaped projectiles form part of the prior art, thus determining a number of different ways of constructing the wing and wing shedding mechanisms used in such projectiles, and when and when to shed the wing. There is an arrangement to do this. Since these elements do not form part of the actual invention, they will not be discussed in more detail herein.

In accordance with the present invention, the metal annular type that can be fired from the wire barrel with no rotation or complete rotation, in that the original annular copper shell of the projectile is screwed to the projectile body by a female thread over the male thread and fixed against torsion. A solution to the problem of manufacturing shell projectiles is provided. Thus, the basic concept behind the present invention is that if a projectile having the characteristic type of the present invention is fired from the liner barrel, and if the projectile needs to leave the barrel without rotation, the line is when the liner forces the rotation of the liner. However, it is not necessary to transmit the rotation of the platform itself to the projectile, but instead use rotation to move backwards along the projectile screw in the projectile's firing direction. For this purpose, the work observed in the firing direction of the projectile must have a sufficient number of turns available behind the screwed bullet posts in the projectile and the screws of the projectile and the shotgun must have screws in the same direction as the barrel steel wire. Thus, at launch, the sleeping rotation of the sleeping platform relative to the projectile body is replaced by the rotation and movement of the copper platform which is screwed backwards along the screw of the projectile body. If the range of motion of the platform along the projectile screw is instead hindered prior to firing, the rotation of the platform will still be transmitted to the projectile, and then the projectile will leave the barrel, from which the projectile will be entirely conventional rotating stable projectile. Is fired. Inherently, the simplest way to lock a screwed carriage is to screw it to a stop which limits the projectile screw rearward in the firing direction of the projectile.

Thus, projectiles or shells of a particular type of the present invention are distinguished by means of a facility according to the circumferential surface of the male thread in which the female threaded copper shell is screwed. In order to make the projectile switchable between the no-rotation and the rotational firing modes, the length of the projectile screw behind the platform with the screw-mounted shell in the forward position is at least equal to the number of turns of the wire in the wire barrel intended to launch the projectile. The number of turns must be included. If the bullet in this forward position is in the firing direction, the projectile will leave the barrel without rotation. Instead, before firing, the projectile will leave the barrel as a rotationally stable projectile at full rotation consistent with the barrel used, if the bullet is screwed back to a fixed rear stop position in the firing direction.

The Bofors 57 mm automatic gun barrel, which is required to be able to fire both a rotationally stabilized explosive shell and a wing stabilized solid core projectile for a non-rotating armored tube, has a wire twist that provides rotation of 24 × 57 mm. In common language, the barrel is said to have a 24-caliber liner twist. This means that the rotationally stable shell performs rotation of a barrel length of 1368 mm. Since the barrel has a length of 57 × 70, or 3990 mm, the shell turns to 3880/1368 = 2.9 revolutions while traveling through the barrel. When a rotationally stable projectile is fired from the barrel, if the muzzle velocity is 1025 m / s, approximately 45,000 revolutions per minute are obtained.

Since the barrel liner does not exceed a few rotations, depending on whether rotational firing or no-rotational firing is required, the movements that can occur before and after the projectile fitted in accordance with the present invention will not significantly interfere with the ballistics of the projectile.

The complete projectile according to the present invention, whether with a rotary or a no-rotational firing, and accordingly, after leaving the liner barrel, whether the bullet is in the forward position or the rear position when the projectile leaves the barrel. On the contrary, in the case of a standard caliber armored solid core projectile, fired with the aid of a so-called breakout barrel that must leave the actual projectile as soon as the projectile leaves the barrel of the barrel. to be. Therefore, at this time, the screw of the release barrel is configured such that the shell is not screwed out of the release magazine at a suitable time, and the bullet of this variant is not intended to prevent the non-screwed cartridge from damaging the wings of the solid core projectile. It is advantageous if the stand can be supplemented by a rupture line which ensures that it breaks into smaller parts as soon as it leaves the breakaway bin. By substituting the conventionally used sleeping shells in an escape shell of a solid core for an antitank of a barn caliber having screwed copper shells constructed in accordance with the invention, which are not threaded during the progress of the projectile through the barrel, advantageously, It is also possible to replace the breaking strips or corresponding structures that have conventionally been used to hold the escape bins made up of a number of different parts together. Whereas the platform rests along the threaded engagement of the escape bin, the platform will effectively hold the portions of the escape bin together as soon as the escape bin leaves the part of the escape bin.
