DK 165523BDK 165523B
Opfindelsen angår småkalibret riffelammunition bestående af et projektil monteret i en plastsabot, som kan sønderdeles, og som stabiliserer projektilet ved dettes udskydning gennem riffelløbet, men som sønderdeles, når den 5 forlader løbets munding, således at kun projektilet fortsætter banen mod målet.BACKGROUND OF THE INVENTION The present invention relates to small-caliber rifle ammunition consisting of a projectile mounted in a disintegrating plastic sabotage which stabilizes the projectile upon its firing through the rifle but which disintegrates as it exits the mouth of the barrel so that only the projectile proceeds to the target.
"Lille kaliber" anvendes i nærværende ansøgning i betydningen et kaliber på 0,50 tomme (ca. 12,7 mm) eller mindre. Der har praktisk taget ikke fundet nogen udvikling 10 sted inden for området med småkaliber sabot'er i plast efter udviklingen af den plastsabot til jagtammunition, som er omtalt i US-patentskrift nr. 3.164.092, og som angår den velkendte "Accelerator" jagtpatron fra Remington, hvori anvendes et blyprojektil i en polycarbonatsabot. Tilsvarende 15 opbyggede sabot'er er omtalt i US patentskrift nr. 3.311.061."Small caliber" in the present application is used in the sense of a caliber of 0.50 inch (about 12.7 mm) or less. Virtually no development has taken place in the field of small-caliber sabotages in plastic following the development of the hunting-ammunition plastic sabotage disclosed in U.S. Patent No. 3,164,092 to the well-known "Accelerator" hunting cartridge from Remington, using a lead projectile in a polycarbonate sabot. Similarly, 15 built-up sabotas are disclosed in U.S. Patent No. 3,311,061.
Der er et stadig ønske om at kunne forøge hastighed, hårdhed og densitet af underkalibrede letvægtsriffelprojektiler således, at de kan trænge igennem hårdere og tykkere mål. Hvorledes dette skulle udføres i tilknytning til kendte 20 rifler har der imidlertid ikke været nogen viden om på grund af det tættere projektilmateriale, som er nødvendigt hertil, og den manglende evne hos kendte sabot'er, såsom omtalt i ovennævnte US-patentskrift nr. 3.164.092, til at modstå de kræfter, som overføres ved sådanne udsendelser. I almin-25 delighed er sådanne sabot'er udformet til at blive revet bort fra projektilet ved udskydningen som en samlet enhed, og erfaringerne er gået imod anvendelsen af sprøde materialer ved opbygningen af en sabot, idet et sådant materiale brydes i stedet for at blive revet bort.There is still a desire to be able to increase the speed, hardness and density of sub-calibrated lightweight rifle projectiles so that they can penetrate harder and thicker targets. However, how this should be done in conjunction with known rifles has been unknown because of the denser projectile material required for this and the inability of known sabotages, such as disclosed in the above-mentioned U.S. Patent No. 3,164. .092, to withstand the forces transmitted by such broadcasts. In general, such sabots are designed to be torn away from the projectile by the launch as a single unit, and experience has gone against the use of brittle materials in the construction of a sabot, breaking such material instead of being torn away.
30 Problemet løses med et projektil og en sabot af den indledningsvis omtalte art, som er karakteristisk ved at være udformet som angivet i krav l's hhv. krav 10's kendetegnende del.The problem is solved by a projectile and a sabot of the type mentioned at the outset, which are characteristic of being designed as set forth in claim 1 and 1, respectively. The characteristic part of claim 10.
Ved den foreliggende opfindelse er der tilvejebragt 35 et småkalibret projektil, som består af en sabot, som er tilstrækkelig stærk til at blive ført ud af et riflet løb iIn the present invention, there is provided a small-caliber projectile which consists of a sabot sufficiently strong to be carried out of a rifled barrel.

2 ét stykke ved maksimalt kammertryk på mere end 70.000 "copper crusher" trykenheder (CUP), men som derefter umiddelbart sønderbrydes, således at den herefter ikke nedsætter projektilhastigheden eller gør projektilet unøjagtigt. Sammen-5 lignet med de i US patentskrift nr. 3.164.092 og nr.2 one piece at maximum chamber pressure of more than 70,000 "copper crusher" printing units (CUP), but which is then immediately disrupted so that it does not subsequently reduce the projectile speed or render the projectile inaccurate. Compared to those of US Patent Nos. 3,164,092 and Nos.
3.311.061 nævnte sabot'er udmærker den ved den foreliggende opfindelse tilvejebragte sabot sig ved at være fremstillet af et forholdsvis sprødt materiale, som sønderbrydes ved projektilets udskydning i stedet for at blive revet bort.3,311,061 said sabots distinguish the sabot provided by the present invention by being made of a relatively brittle material which is broken by the projectile's firing rather than being torn away.
10 Ved den foreliggende opfindelse er der tilvejebragt projektil af lille kaliber (12,7 mm eller mindre), som består af en underkalibret, hård, pansergennemtrængende metalkerne, som er placeret aksialt i en plastsabot, hvilken sabot frigør sig fra kernen stort set umiddelbart, når projektilet for-15 lader riffelløbet efter affyringen. Sabot'en består af en muffe, som er lukket i den ene ende og åben i den anden til indsættelse af kernen, idet den lukkede ende af sabot'en er udformet med en massiv bund placeret ved kernens bagende, og sabot'en er opbygget af et plastmateriale med tilstræk-20 kelig trækstyrke, forskydningsstyrke og sammentrykningsstyrke til at kunne modstå den eksplosive udsendelse af projektilet fra løbet fra en riffel med en intakt sabot, før denne frigør sig fra projektilet, medens sabot'en er opbygget af et relativt sprødt plastmateriale, som ikke kan overvinde centri-25 fugalkraften og de aerodynamiske kræfter, som påvirker sabot 'en, når projektilet forlader riffelløbet, idet disse kræfter bevirker, at sabot'en sønderbrydes stort set umiddelbart efter, at projektilet har forladt løbet, hvorved kernen frigøres således, at den kan fortsætte i sin bane uhindret.The present invention provides a small caliber projectile (12.7 mm or less) which consists of a sub-calibrated, hard, armor piercing metal core located axially in a plastic sabot, which sabot frees from the core almost immediately. when the projectile for-15 leaves the rifle barrel after firing. The sabot consists of a sleeve which is closed at one end and open at the other for insertion of the core, the closed end of the sabot being formed with a solid bottom located at the rear of the core and the sabot being constructed of a plastic material having sufficient tensile strength, shear strength and compressive strength to withstand the explosive emission of the projectile from the barrel of an rifle with an intact sabot before releasing it from the projectile while the sabot is made up of a relatively brittle plastic material which cannot overcome the centrifugal force and the aerodynamic forces affecting the sabot as the projectile exits the rifle, as these forces cause the sabot to disintegrate almost immediately after the projectile has left the barrel, thus releasing the core that it can continue in its lane unhindered.
30 Endvidere er der ved opfindelsen tilvejebragt en sabot til anvendelse i et sådant projektil, hvilken sabot består af en muffe, som er lukket i den ene ende og åben i den anden ende til indsættelse af kernen, idet den lukkede ende af sabot'en er udformet med en massiv bund placeret 35 ved kernens bagende, og sabot'en er opbygget af et plastmateriale med tilstrækkelig trækstyrke, forskydningsstyrke og 3Further, the invention provides a sabot for use in such a projectile, which sabot consists of a sleeve which is closed at one end and open at the other end for insertion of the core, the closed end of the sabot being formed with a solid base located 35 at the rear of the core, and the sabot is constructed of a plastic material of sufficient tensile strength, shear strength and 3

Det må foretrækkes, at sabot'en er fremstillet i et plastmateriale med en trækstyrke og en forskydningsstyrke (ASTM D 1708 hhv. ASTM D 732) på mindst 12.000 psi (82.74 MPa), en sammentrykningsstyrke på mindst 15.000 psi (103,43 15 MPa) og en Izod kærvslagprøve (ASTM D 256) under ca. 12 feet-pound/inch (6.4 Nm/cm). De mest foretruke plastmaterialer er (a) termoplastisk, amorft polyetherimidresin, (b) termoplastisk polycarbonatresin forstærket med 20 glasfibre.It is preferred that the sabot be made of a plastic material having a tensile and shear strength (ASTM D 1708 and ASTM D 732, respectively) of at least 12,000 psi (82.74 MPa), a compressive strength of at least 15,000 psi (103.43 15 MPa) ) and an Izod notch impact test (ASTM D 256) under ca. 12 feet-pounds / inches (6.4 Nm / cm).

Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, på hvilken: 25 fig. 1 er en afbildning af et snit langs aksen gennem én ved opfindelsen tilvejebragt sabot og projektil, fig. 2 er en isometrisk afbildning af den i fig. 1 viste skive, som anvendes i projektilet.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with reference to the accompanying drawings, in which: 1 is a sectional view taken along the axis through a sabot and projectile provided by the invention; FIG. 2 is an isometric view of the embodiment of FIG. 1, which is used in the projectile.
Et projektil 10 er vist med en større cylindrisk 30 bageste del 12, som er ført i en midtstillet udboring 14 på en i hovedsagen cylindrisk udformet sabot 16 af plast, som er udformet med en massiv cylindrisk bageste basisdel 18 og en rørformet forreste del 20. Den forreste del 20 indbefatter et antal buede dele 22, som er forbundne med af svækkede 35 stykker 24, som forløber aksialt på den forreste del 20. De afsvækkede stykker 24 er udformede med indbyrdes adskilteA projectile 10 is shown with a larger cylindrical 30 rear portion 12 which is guided in a centered bore 14 on a generally cylindrical shaped sabot 16 of plastic formed with a solid cylindrical rear base 18 and a tubular front portion 20. The front portion 20 includes a plurality of curved portions 22, which are joined by attenuated 35 pieces 24 extending axially on the front portion 20. The attenuated pieces 24 are formed with spaced apart ones.

4 aksiale riller eller fuger 26 på den indre overflade af den forreste del 20 og er tilspidsede ved de indre ender for at koncentrere brudkræfter i disse punkter, således at sabot'ens brudlinier i en vis udstrækning er forudbestemt. Den ydre 5 flade 28 på sabot'en 16 er udformet som en ubrudt cylinderflade.4 axial grooves or joints 26 on the inner surface of the front portion 20 and are tapered at the inner ends to concentrate fracture forces at these points so that the sabot's fracture lines are predetermined to some extent. The outer surface 28 of the sabot 16 is formed as an unbroken cylinder surface.
Mellem bunden 30 i udboringen 14 i sabot'en 16 og den bageste ende 32 af projektilet 10 er placeret en firkantet skive 34 af metal og med afrundede hjørner (også vist i 10 fig. 2), hvilken skive er placeret radialt indad og udad i forhold til den indre overflade på den midtstillede udboring 14, således at skiven overfører accelerationskræfterne under den eksplosive af skydning af sabot 16 og projektil 10 sammen gennem et riflet geværløb (ikke vist), og for at forhindre 15 et rotationsmæssigt slip mellem sabot 16 og skive 34 under den rotationsmæssige acceleration af sabot 16 under en sådan udskydning. Skiven 34 kan være udformet på anden ikke cirkulær, symmetrisk vis, idet den kunne være udformet som en polygon (pentagon eller hexagon, osv.), en elipse eller som 20 et tandhjul. Skiven 34 er udformet med afrundede hjørner for at nedsætte påvirkningskoncentrationer i hjørnerne og for at muliggøre anvendelsen af skiver med større areal.Between the bottom 30 of the bore 14 of the sabot 16 and the rear end 32 of the projectile 10 is placed a square disc 34 of metal and with rounded corners (also shown in Fig. 2), which disc is radially inward and outwardly relative to the inner surface of the center bore 14 so that the disk transmits the accelerating forces during the explosive of shooting sabot 16 and projectile 10 together through a rifled rifle barrel (not shown) and to prevent a rotational slip between sabot 16 and disk 34 during the rotational acceleration of the sabot 16 during such an extension. The disc 34 may be formed in another non-circular, symmetrical manner, in that it may be formed as a polygon (pentagon or hexagon, etc.), an ellipse or as a gear. The disc 34 is formed with rounded corners to reduce impact concentrations in the corners and to enable the use of larger area discs.
Den ydre overflade 28 på sabot 16 er udformet med en i hovedsagen konstant diameter fra basisdel 18 op til et 25 aksialt punkt 36, som er placeret foran tyngdepunktet 38 for projektilet 10 for at formindske ukontrollerede bevægelser af projektilet 10 under dettes passage gennem et riflet geværløb, hvilket kunne indtræde, hvis punktet 36 var placeret bag ved tyngdepunktet 38. I en anden udførelsesform, 30 som er vist kontureret, er et tungere projektil 10a vist monteret i en identisk sabot og med et tyngdepunkt 38a, som ligeledes ligger bag punktet 36.The outer surface 28 of the sabot 16 is formed with a substantially constant diameter from base portion 18 up to an axial point 36, located in front of the center of gravity 38 of the projectile 10 to reduce uncontrolled movements of the projectile 10 during its passage through a rifled rifle barrel. which could occur if the point 36 was located behind the center of gravity 38. In another embodiment, 30 shown contoured, a heavier projectile 10a is shown mounted in an identical sabot and with a center of gravity 38a which is also behind the point 36.
Sabot 16 er tilvejebragt med en kaliber på 7,62 mm og bærer et wolframprojektil 10 på 52 grain (ca. 3,4 g) 35 eller et wolframprojektil 10a på 57 grain (ca. 3,7 g) vist kontureret.
