Description

The invention relates to a newly designed long-range ammunition in three different Variations that are designed for military firearms.

The wars of the past year (1999) in which our armed forces in Kosovo of the former Yugoslavia for humanitarian reasons have also been involved once again proved that at all in the last phase of the conflict In terms of infantry weapons, the definitive neutralization of aggressive, misanthropic Forces cause that therefore their construction u. Ammunition level as high as possible henst must be optimized.

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

The object of the invention is therefore primarily for infantry weapons to design applicable ammunition by means of which the infantry divisions of such Aggressors can be fought without being within range of the floor whose firearms have to go into position.

This object is achieved by the features in claim 1.

Advantageous embodiments of the invention are characterized in the claims below net.

The cartridge-guided long-range ammunition according to the invention is divided into three Variations, i. H. in marksmen / snipers as well as spreading fire long-range fire weapons, their specifically designed projectiles when the propellant is ignited by the expanding gas pressures, via individually designed thrust piston bottoms are made of ballistically inert material in the barrel of the weapon and after leaving mechanically detach itself from these thrust piston bottoms from the mouth thereof, after which they are due to their extremely streamlined shape u. regarding to conventional projectiles reduced mass, one in terms of flight and u. Tread extremely potentized ballistic curve.

The long-range ammunition variant, which is designed for rifle weapons, is in Regarding metal sleeve u. Propellant charge analogous to conventional patronized shooters weapon ammunition constructed, but has a projectile, which in the longitudinal axi alen sectional perspective congruent to the teardrop-shaped cross section of an aircraft Wing profile is conformed u. thus in the flight phase from the addition of the resulting translations u. Circulation flow dynamics a specific aerodynamic push-back effect achieved in the functional interaction with the with this design (with the same caliber) implied, spec. decimated  Bullet mass is significant with regard to conventional bullet shapes potentiated airspeed u. Range - with the same gas pressure parameter - implies.

The long-range ammunition variant, which is for sniper weapons, is regarding their metal sleeve u. Propellant charge analogous to conventional patronized snipers weapon ammunition constructed, but has a longitudinal axial-centric continuous hollow projectile, the radial flanks of which are in the longitudinal axial section perspective congruent to the drop-shaped aerodynamically optimized cross-section of a flight Wings-wing profile are conformed u. thus in the flight phase from the addition the components of the resulting translations u. Circulation flow dynamics achieve an aerodynamic feedback effect, which is functional Interaction with that from this spec. def. centric longitudinal cavity Weight u. Flow resistance reduction with regard to conventional projectile form a significantly potentiated airspeed u. Range at the same Gas pressure parameters implied, which in turn also applies to this type of weapon relevant shooting precision.

The long-range ammunition variant for cluster guns is related to Metal sleeve u. Propellant charge analogous to conventional grit fire cartridges constructed, but has several concentrically integrated in the longitudinal axis Projectiles, which are concentrically hollowed longitudinally and axially, u. their radial flanks in the longitudinal-axial section perspective congruent to the drop-shaped aerodynamically optimized cross section of an aircraft wing profile conform are lubricated u. thus in the flight phase from the addition of the components of it resulting translations u. Circulation flow dynamics an aerodynamic Achieve push-back effect, which in functional interaction with that of this spec. def. centric longitudinal cavity achieved weight u. Flow resistance Reduction with regard to conventional projectile forms, a significantly potentiated Airspeed u. Range implies with the same gas pressure parameter. Since this spec. def. longitudinally hollowed projectiles with gas pressure accelleration after discharge from the barrel mouth due to their different mass u. Flow resistance treading ballistic curves that differ from each other can therefore the opponent can be fought simultaneously over several distances in one shot. The detailed explanation about construction u. Function of the illustrated invention is carried out then based on the drawings.

In FIG. 1, the predestined for sniper weapons wide rounds of ammunition is illustrated whose elmentare- / functional explanation, angliedert here using the reference numerals "1-4" in the longitudinal axial cross-section.

"1" = (bottle neck) cartridge case, its materialization; Shaping; Sleeve bottom u. Ignition charge analogous to conventional infantry cartridges for Scharf protective weapons are constructed.

"2" = powdered propellant, its elemental composition and mass is defined analogously to conventional infantry cartridges for sniper weapons, their projectile muzzle velocity (Vo) between 840 u. 990 m / s established is.

"3" = thrust piston bottom, which from ballistic inert but sufficient heat u. pressure-resistant material (carbon fiber reinforced plastic-CFRP; PVC; PTEE; PP or glass fiber reinforced plastic GRP) is manufactured u. like here in the blur shown cut, conforming to the lower segment of the aircraft wing Profile of the projectile "4" held parallel to it, with spec. def. print is present.

When the propellant medium expands, this element transmits its pressure evenly linear on the centrically longitudinally hollowed bottom of the projectile "4" until the same leaves the barrel muzzle.

Immediately afterwards, the pre-release in the cartridge u. subsequently in the run to the rear lateral projectile segment under spec. def. Preload (which prevents the inadvertent loosening of the projectile before the shot and is therefore functionally equivalent to the conventional "projectile pull-out force") parallel to the surface of the radial flanks of the projectile held with it, whereby the same - analogous to Fig. 4 - in its front Segment of the suddenly penetrating pneumatic overpressure to be expanded diametrically u. Thus, compared to the hollow projectile that had previously been positively accelerated - not least due to the ballistic inertial mass of this thrust piston bottom - it causes an enormous negative acceleration, which the ballistic curve of this specific gas pressure transmission element (which requires the longitudinally continuous hollow of the projectile) already finished after a few meters / yards.

"4" = specifically aerodynamically drop-shaped, long-range projectile, which according to this compliant aircraft wing structure - analogous to the illustration lung - is axially concentric, continuously hollowed u. thus one versus con conventional long-range bullets (with or without aerodynamic rear cone) Drag reduction manipulation), significantly potentiated flight speed efficiency and Range, because this teardrop-shaped cross section of the symmetrical Radial flanks of this projectile have a specific coaxial in the flight phase  Gives buoyancy / rebound effect, which at the same time implicitly graced the internal flow effect, this projectile around its longitudinal axis of rotation (which results from the moves of the spin swirl) stabilized, which in turn the an obligatory meeting point location over larger distances is obligatory for this type of weapon aerodynamic precision component.  

In Fig. 2 the long range ammunition designed for rifle weapons - with teardrop-shaped, non-hollowed projectile - is shown in the longitudinal axial cross-section, the elementary / functional explanation of which can be found here with reference numbers "1-5".

"1" = (cylindrical) cartridge case, its materialization; Shaping; Sleeve bottom u. Ignition rate defined analogously to conventional infantry cartridges for rifle weapons are.

"2" = powdered propellant, its elemental composition and mass is defined analogously to conventional infantry cartridges for rifle weapons, the Projectile muzzle velocity (Vo) between 280 u. 570 m / s is established.

"3" = thrust piston bottom, which is inert from ballistic, as well as heat and. pressure resistant material (carbon fiber reinforced plastic-CFRP; PVC; PTEE; PP or glass fiber reinforced plastic-GRP) is manufactured u. as shown here in the unshaded cut conforms to the rear segment of the aircraft wing profile of the projectile "4", with spec. def. Pressure is present.

When the propellant medium expands, this element immediately transmits its pressure moderately linear on the rear - symmetrical - drop - shaped bottom of the Projectile "4" until it has passed the muzzle.

Immediately afterwards solve the in advance in the cartridge u. subsequently in the run under spec. def. Preload (which prevents the unintentional loosening of the projectile before the shot is fired and is therefore functionally equivalent to the conventional "projectile pull-out force") parallel radial flanks of the projectile held with it, the same - analogous to Fig. 5 - in their front Segment of the instantaneously penetrating pneumatic overpressure can be expanded diametrically and Thus, compared to the previously positively accelerated un-hollowed, teardrop-shaped projectile - not least due to the ballistic inertia of this specific thrust piston head - an enormous negative acceleration causes the ballistic curve of this gas pressure transmission element (which is the otherwise unfavorable impact angle of the propellant gas). Medium required) ended after a few meters / yards.

"4" specifically aerodynamically drop-shaped, long-range projectile, which is voluminous (longitudinally-un-hollowed), with symmetrical conformity, longitudinally circumferential aircraft wing structure, one with regard to convention light long-range bullets (with or without aerodynamic rear cone Drag reduction manipulation), significantly potentiated flight speed efficiency and Range, since this cross-section in the shape of a teardrop runs around it Rifle projectile in the flight phase a specifically coaxial  Gives buoyancy / push-back effect.

"5" = cross-axial hole cut in the rearmost, drop-shaped the segment of this specific rifle projectile, which enables that with operative removal of the same Surgeon no longer the same cut out laterally, but using a specific surgical pull kens, which with this (in this regard. legally standardized in the diameter) hole saving is compatible from the Gunshot wound with the least consequential injury can pull out tongues.  

In FIG. 3, designed for multi-distance scattering fire-protecting weapons cartridged wide rounds of ammunition is illustrated in longitudinal axial cross-section whose elementare- / functional explanation angliedert here with reference to the numerical reference "1-4".

"1" = (cylindrical) cartridge case, its materialization; Shaping; Sleeve bottom u. Ignition rate analogous to conventional scattering fire (shot) cartridges are defined.

"2" = powdered propellant, its elemental composition and mass is defined analogously to conventional scattering fire (shot) cartridges.

"3" = thrust piston bottom, which is inert from ballistic and heat u. sufficient pressure resistant material (carbon fiber reinforced plastic CFRP; PVC; PTEE; PP or. glass fiber reinforced plastic GRP) is manufactured u. like here in the unshaded Section shown, with spec. def. Print the diametrically integrated, lengthways axially continuously hollowed, scattered fire long-range shell projectiles "4" in front of Lock the shuffle sufficiently.

When the propellant medium expands, this element transmits its thermodynamic energy evenly linearly onto the concentrically longitudinally hollowed scattering fire sleeve projectiles "4" until they have definitely simultaneously passed the barrel muzzle. Immediately afterwards, the pre-release in the cartridge case u. follow-up still in the run under spec. def. Preload (which prevents the inadvertent loosening of the concentric, diversely dimensioned shell shot projectiles "4" and is functionally added to the conventional "projectile pull-out force") on the rear, drop-shaped radial flanks of the shell shot-projectiles " 4 "radial flanks of this thrust piston bottom" 3 "lying parallel to the surface of the H. projectiles" 4 "previously held internally in the cartridge / barrel, the same - analogously to FIG. 6 - in their front segments of the pneumatic backflow simultaneously penetrating therein Overpressure can be expanded diametrically and thus compared to the H.-projectiles "4", which had previously been positively accelerated along the longitudinal axis - not least due to the ballistically inert mass of this spec. Multiprojectile thrust piston bottom "3" imply a significant negative acceleration, which the ballistic curve of this specific gas pressure transmission element (the necessity of which is based on the concave longitudinally extending cavities of these H. projectiles "4") after only a few meters 1 yards finished.

"4" = specifically teardrop-shaped aerodynamically optimized long-range projectiles, which are in accordance with an aircraft wing structure conforming to their radial flanks - analogous to the illustration - in each case longitudinally axially concentric, continuously hollowed out and thus a compared to conventional long-range bullet projectiles (with or without aerodynamic tail cone flow resistance reduction manipulation), significantly increased flight speeds and. Ranges have, since this drop-shaped cross-section of the symmetrical radial flanks of these H. projectiles in the flight phase each have a spec. def. give coaxial buoyancy / push-back effect, which here simultaneously through the respective implied internal flow effect, these diversely dimensioned H. projectiles around their longitudinal axial axes of rotation (which from the trains of the barrel or from the specific drivers of the push piston bottom "3" - analogously Fig. 6 - results) stabilized.

Since this spec. def. If aerodynamically optimized H. projectiles differ from one another in terms of mass and diametric / longitudinal-axial expansion, the same - analogously to FIG. 6 - tread differently expanded ballistic curves.

This ballistic longitudinal-axial scattering effect enables simultaneous shooting with every shot Fighting the enemy across diverse distances.  

FIG. 4 shows the thrust piston bottom and the aerodynamically optimized, longitudinally concentrically hollowed long-range projectile of an infantry cartridge predestined for sniper weapons - analogously to FIG. 1 - in the flight phase, immediately after exiting the barrel muzzle.

Both the pusher piston crown and the Weit already advanced in this phase Shot-hollow projectile are here by means of hatching in the longitudinal axial cross-section indicates.

Those running internally / externally along the longitudinal axis of the projectile Arrow lines indicate the aerodynamic flow pattern permeated air mass.

Since the radially continuous flank of this longitudinally axially hollowed projectile with the transverse The structural structure of an aircraft wing profile is conformed to that here translational / circulation flow effects acting on these drop-shaped radial body a specific aerodynamic lift moment, the Vacuum component in the rear segment has a certain push-back effect analog is u. this H. projectile compared to voluminous long-range projectiles (with or without aerodynamic tail cone flow resistance reduction manipulation lation) significantly potentiated airspeed u. Reach gives what in turn shooting precision (meeting point location) also benefits.

Because the lateral projectile integration flanks of the thrust piston bottom leave behind the barrel muzzle neither from the cartridge case nor from the internal barrel wall are formed symmetrically parallel under defined pressure, the front seg gapes ment of this transmission element under the back influence of the in this phase still effective attacking powder gas pressure apart in the direction of the arrow.

This diametric expansion on the front is further potentiated by the mechanical separation of the now no longer implied laterally wedged projectile, with this wedge-shaped radial cavity with enormous delays the penetrating air masses penetrate, which is a significant negative acceleration effect compared to that in this phase based on "Vo" continue to effect positively accelerated projectile.

This different acceleration mode of the gas pressure transmission thrust piston mentions of the in-phase mechanically released H. projectile Graphically illustrated via the progressively blunted arrow segments.  

In Fig. 5, the thrust piston bottom and the aerodynamically drop-shaped, un-hollowed long-range projectile of an infantry cartridge predestined for conventional rifle weapons - analogous to Fig. 2 - is shown in the flight phase, immediately after passing the muzzle.

Both the thrust piston base and the volumi, which had already advanced in this phase Nose long-range projectile are here by means of hatching in the longitudinal axial cross-section indicates.

The arrow lines that run symmetrically externally along the longitudinal axis of the projectile characterize the aerodynamic flow course that penetrates here air mass (external ballistics).

Since this pojectile runs around the side with the cross-sectional contour of an aircraft Wing profile is conformed, the translating / Circulation flow effects on this drop-shaped radial body are specific aerodynamic lift moment, the negative pressure component in the rear Segment a certain reversal effect is similar. thereby this projectile form one compared to conventional long-range projectiles (with or without aerodynamic Tail cone flow resistance reduction manipulation) significantly potentiated Airspeed u. Gives range, which in turn also gives the shot precision (Meeting point location) benefits.

Because the lateral projectile integration flanks of the thrust piston bottom leave behind the barrel muzzle neither from the cartridge case nor from the internal barrel wall are formed symmetrically parallel under defined pressure, the front seg gapes ment of this transmission element under the back influence of this one Phase still effective attacking powder gas pressure in the direction of the arrow apart. This diametric expansion on the front side is further potentiated by this implied mechanical separation of the one that is no longer wedged laterally Projectile, the static air mass in this now exposed radial cavity cause an enormous retarding moment in the atmosphere, which significantly negative acceleration effect compared to that in this phase "Vo" continues to cause positively accelerated projectile.

This different acceleration mode of the gas pressure transmission thrust piston to the long-range projectile that is mechanically released in phase - this Modification - is in this representation via the progressively blunted arrow line elements graphically illustrated.  

In " Fig. 6" the thrust piston bottom and the aerody namically optimized, detached therefrom, longitudinally concentrically hollowed long-range shot-projectile tile of an infantry cartridge predestined for firing guns - analogous to Fig. 3 - in the flight phase, immediately after leaving the Muzzle shown. Both the thrust piston bottom and the H. projectiles, which were already individually advanced in this phase, are identified by hatching in the longitudinal axial cross section.

Since the continuous flanks of these longitudinally axially hollowed H. projectiles each with conform to the cross-sectional structure of an aircraft wing profile, imply the translational / circulation flow effects acting here this drop-shaped radial flank cross section of these projectiles, each a speci fish aerodynamic lift moment, its negative pressure component in the back analogous segment a certain push-back effect is u. this diverse bemes H. projectiles compared to voluminous long-range projectiles (with or without aerodynamic tail cone flow resistance reduction manipulation) signifi edge potentiated airspeed u. Gives reach.

Since these H. projectiles are concentrically integrated into one another before being fired Terms of mass; Diameter; Length u. Flow resistance differ from each other are the same when firing after mechanical release from the push piston floor - analogous to the illustration - accelerated with different intensities u. tread differently expanded ballistic curves, which each Shot enables simultaneous combat of the opponent over diverse distances. If this ammunition is to be fired with rifle trains in rifle weapons, are - analogous to the illustration - in the lower edge segments spec. measured rest to provide recesses, which all diametrically internal projectiles, which not can be contacted directly by twist trains when firing from the compatible raster elevations of the thrust piston bottom (see its Top view representation) parallel to the outermost H. projectile with a twist rotation ver puts.

Since the projectile integration flanks of the Schubkol benbodens after leaving the muzzle neither from the cartridge case nor from the internal barrel wall is formed symmetrically parallel under defined pressure these radial projectile support elements gap this spec. Gas pressure Transmission element under the influence of the back in this phase effectively attacking powder gas pressure to the extent that the mechanical separation of all H. long-range projectiles guaranteed.

Because of this mechanical separation of all H.-W. projectiles also all radial cavities spaces of this thrust piston floor are exposed, the penetrating into it delays static air pressure this ballistically inert body in such a way that the same one significantly negative acceleration effect compared to that in this phase based "Vo" still experiences - each individually - positively accelerated H.-W. projectile, which is graphically identified here using the various intermittent arrow lines.
