"CARROTTED LONG-RANGE AMMUNITION FOR MILITARY FIREARMS

-Broom friction-

The invention relates to a newly designed long-range ammunition in three different variations, which are designed for military firearms. The military conflicts of the past year (1999), in which our armed forces in Kosovo in the former Yugoslavia were also involved for humanitarian reasons, have once again shown that in the final phase of the conflict, it is mainly infantry weapons that bring about the definitive neutralization of aggressive, misanthropic forces and that their design and ammunition level must therefore be optimized as far as possible.

Because a weapon is a good thing if it is used for a good cause.

The invention is therefore based on the object of designing an ammunition that can be used primarily for infantry weapons, by means of which the infantry divisions of such aggressors can be fought without having to take up position within the projectile range of their firearms.
This object is achieved by the features in claim 1. Advantageous embodiments of the invention are characterized in the subclaims.

The cartridged long-range ammunition according to the invention is divided into three variations, i.e. marksman/sniper and scatter-fire long-range firearms, whose specifically designed projectiles, when the propellant charge is ignited, are accelerated by the expanding gas pressures via individually designed piston heads made of ballistically inert material in the barrel of the weapon and, after exiting the muzzle of the weapon, are mechanically released from these piston heads, after which they follow an extremely aerodynamically enhanced ballistic curve in relation to flight distance and speed due to their extremely aerodynamic shape and reduced mass compared to conventional projectiles. The long-range ammunition variant, which is designed for small arms, is constructed in terms of metal casing and propellant charge analogous to conventional cartridged small arms ammunition, but has a projectile which is conformed in the longitudinal axial sectional perspective congruent to the teardrop-shaped cross-section of an aircraft wing profile and thus achieves a specific aerodynamic thrust effect in the flight phase from the addition of the resulting translation and circulation flow dynamics, which in functional interaction with the specifically decimated

Projectile mass implies a significantly increased flight speed and range compared to conventional projectile shapes - with the same gas pressure parameters.

The long-range ammunition variant for sniper weapons is designed in a similar way to conventional cartridged sniper weapon ammunition in terms of its metal casing and propellant charge, but has a longitudinally axially centrally hollowed projectile, the radial flanks of which in the longitudinal axial sectional perspective are congruent with the drop-shaped, aerodynamically optimized cross-section of an aircraft wing profile and thus achieve an aerodynamic thrust effect in the flight phase from the addition of the components of the resulting translation and circulation flow dynamics, which, in functional interaction with the weight and flow resistance reduction achieved from this specifically defined centric longitudinal cavity, implies a significantly increased flight speed and range with the same gas pressure parameters compared to conventional projectile shapes, which in turn also benefits the shooting precision that is particularly relevant for this type of weapon.

The long-range ammunition variant for scatter-fire rifle weapons is designed in a similar way to conventional scatter-fire (shot) cartridges in terms of the metal casing and propellant charge, but has several projectiles which are integrated concentrically into one another along the longitudinal axis, each of which is continuously concave and whose radial flanks in the longitudinal axial sectional perspective are congruent with the drop-shaped, aerodynamically optimized cross-section of an aircraft wing profile, thus achieving an aerodynamic thrust effect in the flight phase from the addition of the components of the resulting translational and circulating flow dynamics, which, in functional interaction with the reduction in weight and flow resistance achieved from this specifically defined centric longitudinal cavity compared to conventional projectile shapes, implies a significantly increased flight speed and range with the same gas pressure parameters. Since this specifically defined Since longitudinally hollowed projectiles follow different ballistic curves due to their different mass and flow resistance values when gas pressure is accelerated after they leave the barrel muzzle, the enemy can be attacked simultaneously at several distances with one shot. A detailed explanation of the structure and function of the invention shown follows with the aid of the drawings.

In Fig. 1 , the long-range ammunition predestined for sniper weapons is shown in longitudinal axial cross-section, the elementary/functional explanation of which is attached here using the reference symbols "1-4" .

"1" = (bottleneck-shaped) cartridge case, the materialization; shape; case base and ignition device of which are designed analogously to conventional infantry cartridges for sniper weapons.

"2" = pulverized propellant charge, the elemental composition and mass of which is defined analogously to conventional infantry cartridges for sniper weapons, the projectile muzzle velocity (Vo) of which is established between 840 and 990 m/s.

"3" - thrust piston base, which is made of ballistically inert but sufficiently heat and pressure resistant material (carbon fiber reinforced plastic - CFRP; PVC; PTEE; PP or glass fiber reinforced plastic - GRP) and, as shown here in the unshaded section, conforms to the lower segment of the aircraft wing profile of the projectile "4" held parallel to it, with a specific defined pressure.

When the propellant gas medium expands, this element transmits its pressure uniformly and linearly to the centrally hollowed-out bottom of the projectile "4" until it leaves the barrel muzzle.

Immediately afterwards, the radial flanks, which are parallel to the surface and are previously in the cartridge and subsequently in the barrel at the rear lateral projectile segment, detach from the projectile held therewith under a specific defined pre-tension (which prevents the projectile from being accidentally released before firing and is therefore functionally equivalent to the conventional "projectile extraction force"), whereby - analogous to Fig. 4 - they are expanded diametrically in their front segment by the suddenly penetrating pneumatic overpressure and thus cause an enormous negative acceleration compared to the hollow projectile which was previously positively accelerated - not least due to the ballistically inert mass of this piston base - which ends the ballistic curve of this specific gas pressure transmission element (which requires the longitudinal axial cavity of the projectile) after just a few meters/yards.

"4" - specifically aerodynamically drop-shaped, optimized long-range projectile, which is hollowed out concentrically and continuously in accordance with this conformal aircraft wing structure - analogous to the illustration - and thus has a significantly increased flight speed and range compared to conventional long-range pointed projectiles (with or without aerodynamic tail cone flow resistance reduction manipulation), since this drop-shaped cross section of the symmetrical radial flanks gives this projectile a specific coaxial

This gives the projectile a lift/recoil effect, which at the same time, through the implied internal flow effect, stabilizes this projectile around its longitudinal axis of rotation (which results from the pull of the barrel spin), which in turn
which gives the point of impact obligatory for this type of weapon an additional aerodynamical precision component at longer distances.

In Fig. 2, the cartridge-loaded long-range ammunition designed for rifle weapons - with a drop-shaped, unhollowed projectile - is shown in longitudinal axial cross-section, the elementary/functional explanation of which is attached here using the reference symbols "1-5" .

"1" = (cylindrical) cartridge case, the materialization; shape; case base and ignition charge of which are defined analogously to conventional infantry cartridges for small arms.

"2" = pulverized propellant charge, the elemental composition and mass of which is defined analogously to conventional infantry cartridges for rifle weapons, the projectile muzzle velocity (Vo) of which is established between 280 and 570 m/s.

"3" = thrust piston base, which is made of ballistically inert, heat and pressure resistant material (carbon fiber reinforced plastic - CFRP; PVC; PTEE; PP or glass fiber reinforced plastic - GRP) and, as shown here in the unshaded section, conforms to the rear segment of the aircraft wing profile of the projectile "4" held by it, with a specific defined pressure.

When the propellant gas medium expands, this element transmits its pressure evenly and linearly to the rear, symmetrical, drop-shaped base of the projectile "4" until it has passed the muzzle of the barrel. Immediately after this, the gases previously formed in the cartridge and subsequently in the barrel under special def. Pre-tensioning (which prevents the projectile from being accidentally released before firing and is therefore functionally equivalent to the conventional "projectile extraction force") causes radial flanks of the projectile held therewith, which are parallel to the surface, whereby - analogous to Fig. 5 - they are expanded diametrically in their front segment by the instantaneous pneumatic overpressure and thus, compared to the previously positively accelerated unhollowed, teardrop-shaped projectile - not least due to the ballistically inert mass of this specific thrust piston base - an enormous negative acceleration which ends the ballistic curve of this gas pressure transmission element (which is required by the otherwise unfavorable impact angle of the propellant gas medium) after just a few meters / yards.

"4" specifically aerodynamically drop-shaped, optimized long-range projectile, which is voluminous (longitudinally unhollowed), with a symmetrically conformal, longitudinally circumferential aircraft wing structure, with a significantly increased flight speed and range compared to conventional long-range pointed projectiles (with or without aerodynamic tail cone flow resistance reduction manipulation), since this drop-shaped circumferential cross-section gives this small arms projectile a specifically coaxial

buoyancy/thrust effect.

"5" = transverse axial hole cutout in the rearmost, drop-shaped segment of this specific firearm projectile, which means that when it is surgically removed, the surgeon no longer has to cut it free laterally, but can pull it out of the gunshot wound with minimal subsequent injuries using a specific surgical pull hook that is compatible with this hole cutout (the diameter of which is legally standardized in this regard).

In Fig. 3, the cartridge-loaded long-range ammunition designed for multi-distance scatter-fire rifle weapons is shown in longitudinal axial cross-section, the elementary/functional explanation of which is given here using the numerical reference symbols "1-4" .

"V- (cylindrical) cartridge case, the materialization, shape, case base and ignition charge of which are defined analogously to conventional scatterfire (shot) cartridges.

"2" - powdered propellant charge, the elemental composition and mass of which is defined analogously to conventional scatterfire (shot) cartridges.

"3" - thrust piston base, which is made of ballistically inert and heat and sufficiently pressure-resistant material (carbon fiber reinforced plastic - CFRP; PVC; PTEE; PP or glass fiber reinforced plastic - GRP) and, as shown here in the unshaded section, locks the diametrically integrated, longitudinally axially continuously hollowed, scatter-fire long-range case projectiles "4" sufficiently vibration-proof before firing with a specific defined pressure.

When the propellant gas medium expands, this element transmits its thermodynamic energy evenly and linearly to the concentrically hollowed-out scatter-fire case projectiles "4" until they have definitely passed the muzzle simultaneously. Immediately afterwards, the projectiles previously in the cartridge case and subsequently in the barrel dissolve under specific def. Pre-tension (which, before firing, prevented the unintentional release of the concentric, diversely dimensioned case shot projectiles "4" and is therefore functionally equivalent to the conventional "projectile extraction force") on the rear, drop-shaped radial flanks of the case shot projectiles "4" on the radial flanks of this thrust piston base "3" that lie parallel to the surface of the H. projectiles "4" held therein beforehand inside the cartridge/barrel, whereby - analogously to "Fig. 6" - the same are diametrically expanded in their front segments by the pneumatic counter-pressure overpressure penetrating them simultaneously and thus compared to the H. projectiles "4" which were positively accelerated longitudinally concentrically beforehand - not least due to the ballistically inert mass of this specific. Multi-projectile thrust piston base "3" imply a significant negative acceleration, which ends the ballistic curve of this specific gas pressure transmission element (the necessity of which is justified by the concentric longitudinal axial cavities of these H. projectiles "4" ) after just a few meters / yards.

"4" = specifically drop-shaped, aerodynamically optimized long-range projectiles, which are hollowed out concentrically along their longitudinal axis in accordance with an aircraft wing structure conforming to their radial flanks - analogous to the illustration - and thus have a higher air resistance than conventional long-range pointed projectiles (with or without aerodynamic tail cone flow resistance reduction manipulation),

have significantly increased flight speeds and ranges, since the teardrop-shaped cross-section of the symmetrical radial flanks gives these H. projectiles a specific, defined coaxial lift/thrust effect in the flight phase, which simultaneously stabilizes these diversely dimensioned H. projectiles around their longitudinal axial rotation axes (which result from the grooves of the barrel or from the specific drivers of the thrust piston base "3" - analogous to Fig. 6) through the respective implied internal flow effect.

Since these specifically aerodynamically optimized H. projectiles differ from one another in terms of mass and diametric/longitudinal axial expansion, they follow differently expanded ballistic curves - analogous to Fig. 6. This ballistic longitudinal axial scattering effect enables the simultaneous combat of the enemy at diverse distances with each shot.

In Fig. 4 , the piston head and the aerodynamically optimized, longitudinally concentrically hollowed long-range projectile of an infantry cartridge predestined for sniper weapons - analogous to Fig. 1 - are shown in the flight phase, immediately after exiting the barrel muzzle.

Both the piston head and the long-range hollow projectile, which has already advanced in this phase, are marked by hatching in the longitudinal axial cross-section.

The arrow lines running symmetrically internally and externally along the longitudinal axis of the projectile indicate the aerodynamic flow pattern of the air mass penetrated.

Since the radial flank of this longitudinally hollowed projectile conforms to the cross-sectional structure of an aircraft wing profile, the translational/circulation flow effects acting on this drop-shaped radial body imply a specific aerodynamic lift moment, the negative pressure component of which in the rear segment is analogous to a certain thrust effect and gives this H. projectile a significantly increased flight speed and range compared to voluminous long-range projectiles (with or without aerodynamic tail cone flow resistance reduction manipulation), which in turn also benefits the shot precision (point of impact).

Since the lateral projectile integration flanks of the piston base are not formed symmetrically parallel by the cartridge case or the internal barrel wall under a defined pressure after leaving the barrel muzzle, the front segment of this transmission element gapes apart in the direction of the arrow under the rear influence of the powder gas pressure that is still effective in this phase. This front diametric expansion is further amplified by the implied mechanical separation of the projectile, which is no longer wedged laterally by it, whereby the air masses penetrate this wedge-shaped radial cavity with enormous deceleration torque, causing a significantly negative acceleration effect compared to the projectile, which is still positively accelerated in this phase on the basis of "Vo".

This different acceleration mode of the gas pressure transmission thrust piston element to the H. projectile released from it in phase is graphically illustrated in this illustration via the progressively blunted arrow segments.

In Fig. 5, the piston head and the aerodynamically drop-shaped, unhollowed long-range projectile of an infantry cartridge predestined for conventional firearms - analogous to Fig. 2 - are shown in the flight phase, immediately after passing the barrel muzzle.

Both the piston head and the voluminous long-range projectile, which has already advanced in this phase, are marked by hatching in the longitudinal axial cross-section.

The arrow lines running symmetrically externally along the longitudinal axis of the projectile indicate the aerodynamic flow pattern of the air mass penetrated (external ballistics).

Since this projectile conforms laterally to the cross-sectional contour of an aircraft wing profile, the translational/circulation flow effects acting on this drop-shaped radial body imply a specific aerodynamic lift moment, the negative pressure component of which in the rear segment is analogous to a certain push-back effect, thus giving this projectile shape a significantly increased flight speed and range compared to conventional long-range projectiles (with or without aerodynamic tail cone drag reduction manipulation), which in turn also benefits the shot precision (point of impact).

Since the lateral projectile integration flanks of the piston base are not formed symmetrically parallel by the cartridge case or the internal barrel wall under defined pressure after leaving the barrel muzzle, the front segment of this transmission element gapes apart in the direction of the arrow under the rear influence of the powder gas pressure that is still effective in this phase. This front diametric expansion is further amplified by the implied mechanical separation of the projectile, which is no longer wedged laterally by it, whereby the static air masses of the atmosphere cause an enormous deceleration moment in this now exposed radial cavity, which causes a significantly negative acceleration effect compared to the projectile, which is still positively accelerated in this phase on the basis of "Vo". This different acceleration mode of the gas pressure transmission thrust piston element to the long-range projectile released mechanically in phase from it - this modification - is graphically illustrated in this illustration via the progressively blunted arrow segments.

Figure 6 -

In the ^u Fig. 6" the piston head and the aerodynamically optimized, longitudinally concentrically hollowed long-range shot projectiles of an infantry cartridge predestined for scatter-fire rifles - analogous to Fig. 3 - are shown in the flight phase, immediately after leaving the muzzle. Both the piston head and the H. projectiles which have already been individually advanced in this phase are marked by hatching in the longitudinal axial cross section.

Since the continuous flanks of these longitudinally hollowed H. projectiles are each conformed to the cross-sectional structure of an aircraft wing profile, the translational / circulation flow effects acting on the drop-shaped radial flank cross-section of these projectiles each imply a specific aerodynamic lift moment, the negative pressure component of which in the rear segment is analogous to a certain thrust effect and gives these differently sized H. projectiles a significantly increased flight speed and range compared to voluminous long-range projectiles (with or without aerodynamic tail cone flow resistance reduction manipulation). Since these H. projectiles are concentrically integrated into one another before firing in terms of mass; diameter; Length and flow resistance differ from each other, they are accelerated with different intensities when fired after mechanically releasing them from the piston base - as shown in the illustration - and each follow differently expanded ballistic curves, which enable the simultaneous combat of the enemy at diverse distances with each shot. If this ammunition is to be fired in rifled weapons with twist rifling, - as shown in the illustration - specially dimensioned locking recesses must be provided in the lower edge segments, which set all diametrically internal projectiles, which cannot be directly contacted by twist rifling, in spin rotation when fired from the respective compatible locking elevations of the piston base (see its top view) parallel to the outermost H. projectile.

Since the projectile integration flanks of the piston base, which are dimensioned with various radii, are not formed symmetrically parallel by the cartridge case or the internal barrel wall under a defined pressure after leaving the barrel muzzle, these radial projectile support elements of this special gas pressure transmission element gape apart under the rear influence of the powder gas pressure that is still effective in this phase to such an extent that the mechanical separation of all H. long-range projectiles is ensured. Since this mechanical separation of all H.-W. projectiles also exposes all radial cavities of this piston base, the static air pressure penetrating it decelerates this ballistically inert body in such a way that it experiences a significantly negative acceleration effect compared to the H.-W. projectiles, which in this phase on the basis of "Vo" are still - individually - positively accelerated, which is graphically indicated here by the various intermittent arrow lines.
