Projectile launched through the barrel of a weapon

This invention relates to a through the barrel

A projectile to be fired from a weapon, in particular a projectile of the sabot type with a core of smaller caliber.

Because of the superior inter-ballistic and terminal ballistic speeds and the resulting increase in performance, it is well known that a projectile core of smaller caliber, which is fired by a cannon or a full-caliber firearm, can penetrate stronger or more resistant targets than is usually possible with armor-piercing ammunition from full caliber is possible. Accordingly, considerable effort has been devoted to the development of a number of types of sabotage projectiles which will serve as the support means for such smaller caliber projectile cores. Often superior penetration properties were achieved to a certain extent,

however, the sabot projectiles known up to now were not satisfactory in every respect. Either they showed specific disadvantages, which also means that the full impact of the Banzer breakthrough can be exploited delayed, or other undesirable properties were introduced or strengthened that impair performance known full caliber bullets have usually not noticeably affected.

These undesirable properties include

a) a reduced accuracy due to the non-axial, deflecting forces and moments that the projectile core affect with a smaller caliber during its separation from the sabot components,

b) Reduction in performance and reliability under difficult ümw 1 conditions, in particular under extreme temperature conditions,

c) a limited scope due to the incompatibility with the feeding and loading devices known automatic guns and firearms,

d) an additional risk to one's own

Troops because of the large scatter cones when dismantling the sabot components thrown off at high speed and

e) increased manufacturing costs, mainly due to the extremely small manufacturing tolerances and the additional material and manufacturing costs are to be carried out.

In order to explain the disadvantages mentioned above, a known sabotage projectile is used below, where the separation between the sabot body and the projectile core with a smaller caliber due to the differential forces caused by dragging between these main components. This full caliber sabotage bullet is essentially cup-shaped and has an axial bore in its nose section, which encompasses the stern section and a considerable section of the Body of the bullet core with smaller, more loose fitting records. If the projectile is fired, the sabotage

Due to its larger diameter, the body is accelerated by the powder gases generated and thus brings about the core with a smaller caliber to an excellent Muzzle velocity. After exiting the muzzle, the larger Sabot body is more powerful aerodynamic Subject to drag forces than the smaller projectile core; there is thereby a relative axial sliding movement between the latter and cause the sabotage body until the separation of the two is complete. When the passitz between the sabot body and the core of the projectile is relatively narrow, then it is clear that due to the friction between the sabot body and the Core additional drag forces are transmitted, which the speed of the projectile core to an undesirable extent and thus significantly impair the main purpose of the sabotage body. On the other hand, if the passport is relatively is dimensioned large, the rotating sabot body does not transmit the correct rotational movement to the projectile core and or or the projectile core is not sufficiently aligned in the axial direction; that helps ensure that accuracy of the projectile core in the target is deteriorated. When these influences are taken into account, it becomes understandable that With such a projectile a very high machining accuracy and very tight manufacturing tolerances are required in order to to ensure an acceptable performance. But because the bullet core is usually made of a very heavy and dense metal, while the parts of the sabot body are preferably made of light, less dense and cheaper materials exist, it is easy to see that the different coefficients of expansion of such different materials lead to large deviations in the fit under different outside temperatures and other environmental conditions, and even if they are manufactured by experienced craftsmen and if the tightest manufacturing tolerances are adhered to. As you can easily see

109810/1639

For example, the fit of a projectile operating satisfactorily at 27 ° C may be too tight or too wide at elevated temperatures or below freezing to achieve adequate performance. On the one hand, raised production studs strive to increase the deflection of the projectile core and reduce the accuracy of the target. Enlarged manufacturing tolerances other hand, lead to an adverse delay, whose disadvantages are cu £ hand. In the end, the accuracy of the bullet and the penetration capacity are subject to considerable fluctuations in the desired operating temperature range between -54 ° C and +52 ° C.

To address these many objections and disadvantages of the

w above-mentioned remedy known projectile, has also been proposed to use for the separation of the projectile core with smaller caliber of the sabot components a combination of aerodynamic and centrifugal forces; the latter are generated by the ordinary angular momentum given to the projectile as it moves through the barrel of the gun. In a typical representative of this type of projectile, the sabot components, which surround the projectile core with a small radial caliber, are shaped like a petal and are separated radially from the projectile core after it emerges from the muzzle, with the overlapping of the aforementioned zen. trifugal forces due to the retarding aerodynamic effect of the surrounding atmosphere. For example, it has been suggested that the leading edges of each petal have an axially inclined surface which captures the airflow and propels the leading edge of the petal outwardly away from the core of the projectile. However, it has been found that separation of this type of projectile leads to deflections and undesirable deceleration of the projectile; because this projectile is therefore also subject to some of the disadvantages mentioned above. In addition, many of these projectiles have additional disadvantages, since they cannot easily be adapted to the rapid firing sequences and self-locking which are characteristic of modern, well-known weapons.

Accordingly, the invention seeks to establish a sabotage projectile assembly, which in the disadvantages to an extent that has not yet been realized known sabot projectiles and delivers a penetration performance that is far superior to that of known armor-piercing projectiles is.

The invention is also based on the aim of an effective and powerful armor-piercing projectile to create with a smaller caliber that can be fired with single fire or continuous fire from known guns of artillery cannons is. The invention is also based on the endeavor to create a sabotage projectile in which the projectile core is separated of smaller caliber leads to the smallest possible deviations from the components with full caliber, without that a noticeable drop in speed at the bullet core smaller caliber is recorded, as it usually occurs under the influence of normal aerodynamic towing forces.

The invention is also based on the endeavor to provide a new angular momentum stabilized, relocatable sabot projectile to create with increased effectiveness that is easy to manufacture and adapt for use in conventional weapons over a wide range of environmental conditions and loads and without significant deviations in performance.

The projectile according to the invention is characterized in that it has a core of smaller caliber, a sabot base part with practically full caliber, which has an engagement surface for engaging the core, a sabot body which practically encloses the core and supports it in a preselectable position, Means to give the projectile a rotary movement during its passage through the barrel, the walls of the sabot body having a plurality of longitudinally extending, a plurality of practically symmetrical wall sections delimiting areas of weakness which are under the influence of the centri formed during the rotation of the bullet -

fugal forces break and thus the wall sections from each other separate and which are also designed so that this separation begins at the stern end of the latter and after the bow end of the projectile progresses.

Embodiments of the subject matter of the invention are described in greater detail below as examples with reference to the drawings explained. Show it:

As FIG. 1 shows, a projectile can with

full caliber have an external shape and symmetry very similar to those of known bullets; It is about at the same time an advantage that could not previously be achieved with most of the dismountable sabot projectiles. One poses, however states that, despite the similar shape of the projectile of FIG. 1, it differs from the known projectiles exist.

The projectile of Fig. 1 has a sabot base part 10, which is made of light metal, such as aluminum,

- 6 109810/1639

can be produced; around a section of the sabot base A circular ring 12 extends around the periphery of this section and is preferably made of a soft metal or a suitable plastic is made; a sabot body 14 can be made of different materials, but it is preferably made of a plastic of relatively made of high toughness and heat resistance; a smaller caliber core 16 (see Fig. 2) is preferred made of a relatively heavy, dense metal. In the embodiment of FIG. 1, the sabot body is seated 14 composed of a cylindrical body 20 and a tapered bow shield 24 attached to the bow end of the cylindrical Body 20 is attached.

As shown in particular in FIG. 2, the sabot base part 10 a concave rear surface 30, which has an enlarged impact surface for the application of the propellant gases supplies. The exact shape and the exact dimensions of this rear surface 30 can be chosen arbitrarily, although you can see it in Fig. 2 has preferably given a substantially conical shape. The sabot base part 10 preferably also has a Front part 32, which provides a seat 34 for the base part of the projectile core 16 with a smaller caliber. The bow section 32 also has an enlarged ring section behind the seat surface 34, for reasons that will be explained further below will.

Although the base part of the projectile core 16 with

If a smaller caliber is to come to rest on the seat 34, the projectile core 16 is mainly within the annular recess of the cylindrical body 20 connected. The wall made of plastic which is limited in this way in the cylindrical body 20 has a practically uniform thickness and firmly encloses the core 16 of the smaller caliber; she supports the latter in such a way that the longitudinal axis of the bullet core is aligned with the axis of rotation of the full-caliber bullet.

Preferably the front inner surface

26 of the body section constricted or slightly tapered, specifically at approximately the same angle as the associated bow section of the projectile core with a smaller caliber, so that the cylindrical portion 20, the projectile core 16 from lateral movements and safely protected from forward movements beyond a preselectable limit. The bow section of the projectile core with the smaller caliber extends through the wall of the cylindrical portion 20 and beyond it; the bow section becomes enclosed and protected by the bow shield 24 with the front end of the cylindrical portion 20 by means of each other matching threaded sections 40,42 is connected.

* As Fig. 3 shows, the wall of the cylindri-

see section 20 when viewed in cross-section a plurality of wall sections 22 on. Although the embodiment shown in FIGS. 1-3 has a number of four wall sections 2 , the cylindrical portion may have any number of wall portions, such as five or six, that meet the are subject to the conditions described below. The wall sections 22 are formed essentially symmetrically and are separated from one another by elongated slots 28; these extend from the rear end of the cylindrical section 20 in the forward direction for most of the length of the latter, ending just before the farthest forward position of the cylindrical section 20.

The purpose of the slots 28 is to provide lines of weakness for the decomposition of the cylindrical section 20, so that the latter automatically enters the symmetrical wall sections under the influence of outwardly directed radial forces 22 falls apart. Furthermore, the slots 28 end at such a point that the unbeaten nose portion of the cylindrical Section 20 has a greater resistance to rupture against radial loading than the rear section of the cylindrical Body 20. In the illustrated embodiment, the slots 28 extend through the entire wall thickness of the cylindrical body 20 through, although other cutting depths are also permissible, as explained below

10 9810/1639

will.

It should also be noted that the rear end

of the cylindrical portion 20 is also notched, or has a slightly reduced diameter to a thin Record retaining ring 44 which is essentially flush with the outer surface of the projectile. The inner surface of the cylindrical portion 20 is provided with an annular recess 38 around the thickened annular base portion 36 to include. The sabot bullet is then put together in a known manner by connecting the bullet core with a smaller one Caliber inserted into the sabot body 14, this connects to the base part 10 after the wall sections 22 from each other bent away, and by finally bringing the base part 10 and the sabot body 14 so close to one another, until the thickened bow section 36 of the base part 10 comes to rest in the recess 38 of the cylindrical section 20 and the elastic wall segments 22 snap into their rest position over the base section 32, as FIG. 2 shows. To the Finally, the locking ring 44 is attached to secure the rear ends of the strap parts 22 and to prevent accidental disassembly to prevent during subsequent handling and during loading of the projectile.

As already mentioned, the bow section 24 encloses the bow section of the projectile core 16 with a smaller caliber; it is therefore preferable that the bow section 24 be tapered in a manner similar to that of known projectiles, so that its external outline ensures compatibility with the loading and launching devices of conventional guns. The internal structure of the bow section 24 is not critical as long as it provides sufficient space and protection for the bow section of the smaller caliber projectile core 16. In the embodiment of FIGS. 1-3, elongated notches 46 are also arranged symmetrically at a distance from one another around the base part of the bow shield 24; the number of these

Ji

Notches 46 are preferably the same as the slots in cylindrical portion 20. The purpose of notches 46 is in that they facilitate the symmetrical dismantling and throwing off of the bow shield 24.

The bullet described above can be combined with a known powder cartridge or in another way for Firing from a gun or a firearm can be adjusted as you like. In the illustrated embodiments the projectile is intended to be fired from a barrel, the inner wall of which is drawn helically in a known manner.

fe If necessary, however, other means of generating a Angular momentum stabilization of the projectile can be applied during flight.

The act of separating the various

Sabotage components after the launch proceeds essentially in the following steps:

At the moment of launch, the projectile 10 is accelerated into the barrel of the firearm; comes with it the guide ring 12, which has a somewhat larger outer diameter, comes into contact with the trains of the barrel and causes it a rotation of the bullet, which continues its movement under the pressure of the expanding powder gases. The leadership

) Ring 12 also prevents the powder gases from flowing around; it rotates in the same direction as the barrel is pulled, and thereby transmits an angular momentum to the sabot base part 10 and thus also to the other sabot components. It should be noted that the angular momentum affects the projectile core 16 smaller caliber is granted because of the strong frictional forces at the interface between the seat 34 and the Projectile core 16 caused by the strong acceleration of the projectile be generated. If necessary, the slip resistance at this interface can even be increased, and thus the transmission of the full Brehira pulse can be guaranteed by a small, sharp-edged recess or rows γοη such

Recesses in the base part of the projectile core 16 with a smaller one Caliber provides. During the initial acceleration, the softer metal of the sabot base part 14 gets into these recesses pressed in or pressed in, as a result of which the transmission of the torque between the base part 10 and the projectile core 16 is improved will.

To the extent that the projectile passes through the

The length of the run is accelerated through, generates the transmitted Rotational momentum considerable centrifugal forces, which have the tendency to move the wall sections 22 in the radial direction to move to the longitudinal axis of the projectile. However, the walls of the barrel surrounding the projectile counteract these forces, thereby practically maintaining a balance while the bullet is inside the barrel. Immediately after the sabot body 14 exits the barrel however, the resistance to the centrifugal forces of the rotary motion is abruptly reduced. As shown in FIG. 4, the perform Tail sections of the wall sections 22 have the least resistance and tend to fly radially outward, whereby a high tensile stress is exerted on the thin guide ring 44. The guide ring 44 breaks as a result; through the outward bend the stern sections of the wall sections 22, the laying of the sabot components is initiated, while the bow ends are still held in place by the unprotected portion of the cylindrical body 20.

If the sabot base part 10 continues to move forward and finally leaves the muzzle, face them the highly pressurized powder gases within the barrel and escape into the outside air, creating an intense Gas flow is generated, which still has an accelerating effect. These accelerating gases then overtake the projectile and hit the rear ends of the wall sections 22 that have already been partially separated. This exposure increases the effect of centrifugal forces already on the Wall sections 22 act and support the further dismantling

- 11 109810/1 639

the sabot components. It should be noted that this loading has a component in the direction of flight that cancels out the aerodynamic towing forces to a certain extent, which already cause a delay in the projectile. If a certain opening angle of the wall sections 22 is observed the superimposed forces cause the non-slotted portion of the cylindrical portion to break 20; the wall sections 22 are then thrown off in the radial direction, simultaneously with the breaking of the cylindrical section 20. The bow shield 24 is similarly broken down into practically symmetrical sections, which are limited by the notches 46. These bow sections 48 are low in density and therefore become very rapid delayed, whereby the endangerment of the own troops is minimal. Although the impact of the muzzle gases is essential the dismantling and throwing off of the sabot components of this projectile, based on the above Described construction, the projectile core 16 with a smaller caliber itself practically counteracts any detrimental deflection effect the muzzle gases are protected by means of the sabot base part 10, which extends along the flight path on the rear part of the projectile core 16 moved forward.

After the sabot body has been dismantled, the aerodynamic drag forces also delay the sabot base part 10 full caliber very quickly, so that it falls to the ground well in front of the target. The projectile core 16 with a smaller caliber however, it is not influenced or hindered by the radial decomposition of the other components and moves longitudinally the trajectory towards the target with very little loss of speed and very little distraction. Particular attention should be drawn to the separation of the projectile core 16 and sabot base part 10 without a transfer of deceleration forces from base part 10 to projectile core 16 he follows. Fig. 5 shows in a schematic representation the completely

- 12 10 9 8 10/1639

separate components; it should be noted, however, that FIG. 5 cannot necessarily show the components in their geometrically correct assignment, as they can actually results from a decomposition process.

The above-described dismantling of the sabot projectile usually takes place immediately after leaving the Barrel of the gun. However, it is according to the description above It is easy to see that the separation of the sabot components is under the influence of the centrifugal forces triggered by the angular momentum and the impact of the muzzle gases reduces the velocity drop of the smaller caliber projectile core Minimum dimension reduced; the drop in speed is the transmission attributable to the retarding and deflecting forces of the full caliber components that occurred prior to complete separation the latter form of projectile core 16 occur with a smaller caliber. Furthermore, the avoidance of sliding surfaces holds between the core 16 and the other components the frictional forces, which is another source of speed loss represent, to a minimum; Ultimately, this eliminates the requirement to maintain tight manufacturing tolerances. On top of that, it can be seen that the way in which it is dismantled has the effect of the transverse effects on the core of the projectile with a smaller caliber reduced to a minimum that occur during dismantling; in this way becomes much improved Accuracy contributed.

Fig. 6 shows another embodiment;

therein the sabot body 14 has wall sections 52 which may have toothed interfaces 54; these mutually interlock and replace the elongated slots 28 of the embodiment of FIGS. 1-3. The toothed boundary surfaces 54, which extend essentially in the direction of flight, allow the wall sections 52 to be separated off in a manner similar to that described above; however, the serrations allow the transmission of shear forces between the sections 52 and thereby increase the mechanical rigidity of the cylindrical section 20. This is a very desirable feature.

- 13 -

109810/1639

The advantage if the projectile has considerable impact loads is exposed from the outside, as is the case with automatic firearms, the extraordinarily high rates of fire or in the case of firearms with high muzzle speeds. The serrated interfaces 54 also provide a somewhat improved protective effect on the projectile core 16 with a smaller caliber, namely against other environmental conditions, such as moisture, salt spray, dust and the like.

Figures 7 and 8 show a number of modifications made to the projectile of Figures 1-3 can be; such modifications can result from

ψ Position reasons, because of the type of weapon used, for reasons of projectile performance or for other reasons, prove necessary. Attention should first be drawn to the fact that the sabot body 14 of FIGS. 7 and 8 is made in one piece, while in the embodiment of FIGS. 1-3 it consists of two separate sections. It should also be noted that the sabot body 14 can be attached to the sabot base part 10 by means of threaded sections 66, 68 that are matched to one another; the latter are located in the sabot base part 10 or the sabot body 14; The threaded sections 66,68 represent a replacement for the locking ring 44 and for the arrangement shown in FIGS. 1-3. It should also be noted that as

™ Replacement for the continuous, elongated slots 28 resp. the toothed interfaces 34 have elongated scores or notches 64 of noticeable depth in the outer wall of the sabot body can be attached to form lines of weakness in this way; these divide the wall immediately after they break into practically symmetrical wall sections 62, which otherwise exert the same effects as the wall sections 22 or The notches 64 are preferably V-shaped and extend only partially into the depth of the wall of the sabot body 14, which can be seen in particular from FIGS. 8 and 9. In contrast to the continuous slots of the embodiment 1-3, this non-penetrating notch has a

Increasing the mechanical stiffness of the bullet for Episode. In addition, there is the additional advantage that the lower caliber projectile core is completely enclosed by the sabot body 14 so that it is better protected against certain unfavorable environmental conditions. Depending on the strength of the The material used is to measure the depth of the V-shaped notch 64 to ensure that the break of the wall of the Sabot body 14 takes place along the elongated lines in these areas of weakness, under the influence of respective centrifugal force, which under the preselectable conditions of the muzzle velocity and the angular momentum dem Floor is granted.

It should also be noted that the scores or notches 64 are formed so that the wall of the sabotage body 14 weakest and therefore most susceptible to breakage at the rear end and strongest and least susceptible to breakage at Bow end is; therefore, the laying will begin under the centrifugal forces of the angular momentum at the stern of the sabot body 14 and proceed from there towards the bow portion of the sabot body 14. To ensure that the break starts at the stern end, it may be desirable to vary the depth of the score or notch 64 depending on the mechanical Strength properties of the material used in each case; so you can e.g. deepen group 64 at the stern end, the depth gradually decreasing towards the bow end.

As has already been emphasized above, good accuracy of the projectile essentially requires coaxial alignment of the barrel axis, the axis of the sabot body 14 and the axis of the projectile core 16 with smaller caliber. In addition to the fulfillment of this condition, however, there is only a slight fit between the sabot device and core with smaller caliber desirable; the manufacturing tolerances between the sabot base part 10 and the common contact surfaces with the projectile core 16 are neither

tight yet critical.

The embodiment shown in FIG

Another feature is a small cylindrical hole 70 that extends through the bottom of the sabot base 14; this hole 70 provides the flow connection between the rear surface 30 of the sabot base part 14 and the base part of the projectile core 16 with a smaller caliber. Such an opening is useful when tracer projectiles are used want to shoot. The hole 70 forms an access opening so that the burning propellant gases reach the flare Can ignite the rear end of the projectile core with a smaller caliber.

It should also be noted that the seat

for the rear end of the projectile core with a smaller caliber can be let into the sabot base part 10 so far, so that there is a guarantee that there is a noticeable frictional engagement between the side walls of this recess and the projectile core 16 is avoided. In the embodiment of FIG. 8, for example, the seat 72 is in the interior of the annular bore 74, which is provided in the bow section of the sabot base part 14. However, it is particularly important that the Bore 74 has a larger diameter than the base part of the projectile core 16; this way it becomes a smoother one Seat achieved, and the separation of the projectile core 16 from the sabot base part 14 transmits no deceleration forces to the projectile core 16, which would otherwise take place due to the sliding friction.

The basic process of dismantling the sabot takes place

essentially the same for all the modifications described, as already described. In the embodiment of FIGS. 7 and 8, for example, the decomposition begins immediately after the sabot body 14 has emerged from the barrel of the firearm. The separation of the sabot body 14 begins on The stern end, specifically close to the threaded section, and steps from there along the notches 64 in the direction of the bow section

"continued. When the wall sections 62 by centrifugal force of the angular momentum have been partially torn, the rear ends of the wall sections 62 are caused by the outflowing muzzle gases acted upon, whereby the separation is completed and after which the individual wall sections 62 are centrifuged radially will. The best possible throw-off is achieved when all sections are as symmetrical as any possible to be detached; therefore, it is highly desirable that a bullet should be suitable for a given application is designed in such a way that this requirement is met.

Of course, further modifications and applications can be made for the above-described projectiles should be considered. For example, instead of a solid core of smaller caliber and higher Dense also use other types of bullets, such as high explosive bullets, single flechetts, multiple flechetts or the like

The embodiments of the projectile described above are characterized by a relatively simple one Construction, due to its adaptability for use in existing firearms for single and continuous fire, as well by decomposition under the shifting effects of centrifugal force and the force when the muzzle impacts. gases out; the latter feature achieves faster and more effective separation of the sabot components, wherein the greatest possible accuracy and the smallest possible deflection of the projectile core with a smaller caliber on its Trajectory is maintained.
