Description
Oppfinnelsen vedrører et splintprosjektil med bunnbrannrør og drivladningshylse som angitt i innledningen i patentkrav 1. Det dreier seg om et ballistisk prosjektil. The invention relates to a shrapnel projectile with a bottom fire tube and propellant casing as stated in the introduction in patent claim 1. It is a ballistic projectile.
Fra EP 0 365 886 Al og GB 1 177 813 er det kjent et splintprosjektil med bunnbrannrør og som kan forbindes med en drivladningshylse. Lengden til bunnbrannrøret, som ligger i splintmantelen, tilsvarer omtrent lengden til sprengladningen inne i splintmantelen. From EP 0 365 886 A1 and GB 1 177 813, a shrapnel projectile with a bottom fire tube and which can be connected to a propellant charge sleeve is known. The length of the bottom fire tube, which is located in the splinter jacket, roughly corresponds to the length of the explosive charge inside the splinter jacket.
Ved et vingestabilisert artilleriprosjektil ifølge DE-PS 89 235 er en sprengladning og et bunnbrannrør anordnet i en utsparing i hekken. Brannrøret er kort og baserer seg på revolverpatronprinsippet, noe som i dag ikke lenger er tillatt på grunn av de gjeldende sikkerhetsforskrifter. Som følge av det korte bunnbrannrør er sprengstoffets lengde særlig stor sammenlignet med brannrøret. In the case of a wing-stabilized artillery projectile according to DE-PS 89 235, an explosive charge and a bottom fire tube are arranged in a recess in the stern. The firing tube is short and is based on the revolver cartridge principle, which today is no longer permitted due to the current safety regulations. As a result of the short bottom fire tube, the length of the explosive is particularly large compared to the fire tube.
I et gjennomslagsprosjektil ifølge US-H 1235 utgjør lengden av bunnbrannrøret i splintmantelen ca. 60% av sprengstoffets lengde. In a penetration projectile according to US-H 1235, the length of the bottom fire tube in the splinter jacket is approx. 60% of the length of the explosive.
I et artilleriprosjektil ifølge DE-PS 21172 er det anordnet et kort bunnbrannrør, som for en større del ligger inne i splintmantelen. I et artilleri-splintprosjektil ifølge US 4.882.996 krever et bunnbrannrør bare en brøkdel av den for sprengladningen beregnede lengde av splintmantelen. Brannrørets hoveddel ligger utenfor splintmantelen. Ved artifieriprosjektilet holdes som kjent drivladningen adskilt fra prosjektilet, dvs. at ladningene tilføres skytset adskilt fra artilleriprosjektilet. En drivladningshylse blir derfor ikke anvendt. Det betyr at det i samsvar med forholdene i skytset er tilstrekkelig plass i prosjektilets hekkområde for et brannrør. In an artillery projectile according to DE-PS 21172, a short bottom fire tube is arranged, which for the most part lies inside the splinter jacket. In an artillery shrapnel projectile according to US 4,882,996, a bottom fire tube requires only a fraction of the length of the shrapnel jacket calculated for the explosive charge. The main part of the fire pipe is outside the splinter jacket. In the case of artillery projectiles, as is known, the propellant charge is kept separate from the projectile, i.e. the charges are supplied to the projectile separately from the artillery projectile. A propellant charge sleeve is therefore not used. This means that, in accordance with the conditions in the shell, there is sufficient space in the projectile's rear area for a fire tube.
Når det gjelder patronerte prosjektiler, altså prosjektiler med tilhørende drivladnings-hylser, vil det på grunn av forholdene i drivladningshylsen bare stå til rådighet et lite volum for brannrøret der. When it comes to cartridged projectiles, i.e. projectiles with associated propellant casings, due to the conditions in the propellant casing, there will only be a small volume available for the firing tube there.
Hensikten med oppfinnelsen er å tilveiebringe et splintprosjektil med drivladningshylse, hvilket prosjektil gir en bedre virkning i målet. The purpose of the invention is to provide a shrapnel projectile with a propellant casing, which projectile provides a better effect on the target.
Dette oppnås ifølge oppfinnelsen med de kjennetegnende trekk som er angitt i krav 1. This is achieved according to the invention with the characteristic features stated in claim 1.
Fordelaktige videreutviklinger av oppfinnelsen er angitt i de uselvstendige krav. Advantageous further developments of the invention are indicated in the independent claims.
Den nye inventive utforming av splintprosjektilet med et ut over splintmantelens bakre ende forlenget brannrør gir tre forskjellige optimaliseringsmuligheter hva angår The new inventive design of the shrapnel projectile with a fire tube extended beyond the rear end of the shrapnel jacket provides three different optimization possibilities in terms of
prosjektilvirkningen, nemlig en forbedring av gjennomslags virkningen som følge av en masseøking i prosjektilhodet, en optimalisering av de virksomme splinter som følge av en øking av veggtykkelsen i splinthylsen, med bibehold av den vanlige sprengstoffandel, eller en øking av sprengstoffandelen med bibehold av den vanlige tykkelse i prosjektilspissen og splintlegemets vegg. the projectile effect, namely an improvement in the penetration effect as a result of an increase in mass in the projectile head, an optimization of the effective splinters as a result of an increase in the wall thickness of the splinter sleeve, while maintaining the usual proportion of explosives, or an increase in the proportion of explosives while maintaining the usual thickness in the projectile tip and the wall of the splinter body.
Et utførelseseksempel av oppfinnelsen er vist på tegningen. Den eneste tegningsfigur viser et lengdesnitt gjennom en patrongranat. An embodiment of the invention is shown in the drawing. The only drawing shows a longitudinal section through a cartridge shell.
En splintgranat 1 med et kaliber på 30 mm har et bunnbrannrør 2, et styrebånd 3 og sitter i en drivladningshylse 4. A shrapnel grenade 1 with a caliber of 30 mm has a bottom fire tube 2, a guide band 3 and sits in a propelling charge sleeve 4.
En del av granatens spiss 10 er utformet som en massiv gjennomslagskjerne 12. Etter gjennomslagskjernen 12, som har en lengde 14, følger en utsparing 16 med en lengde 18. Utsparingen 16 er delt opp i et konisk og et sylindrisk avsnitt 20,22. Disse avsnittene 20,22 utgjør selve splintmantelen 24. Part of the grenade's tip 10 is designed as a massive penetration core 12. After the penetration core 12, which has a length 14, follows a recess 16 with a length 18. The recess 16 is divided into a conical and a cylindrical section 20,22. These sections 20, 22 make up the splint mantle 24 itself.
I splintmantelen 24 er det et spor 26 for den påpressede drivladningshylse 4. Videre har splintmantelen en gjengeforbindelse 5 for bunnbrannrøret 2. Drivladningshylsens 4 fremre ende er betegnet med 30 og ligger i en avstand 31 fra splintmantelens 24 bakre ende 36 henholdsvis planet 34. Denne avstand 31 utgjør noe mindre enn 1/3 av kaliberet. In the splinter sleeve 24 there is a groove 26 for the pressed propellant sleeve 4. Furthermore, the splinter sleeve has a threaded connection 5 for the bottom fire tube 2. The front end of the propellant sleeve 4 is denoted by 30 and is located at a distance 31 from the rear end 36 of the splinter sleeve 24, respectively the plane 34. This distance 31 is slightly less than 1/3 of the caliber.
Bunnbrannrøret 2 har en totallengde 50 med to omtrentlig like store dellengder, nemlig en indre dellengde 52 og en ytre dellengde 54. The bottom fire tube 2 has a total length 50 with two approximately equal part lengths, namely an inner part length 52 and an outer part length 54.
Bunnbrannrøret 2 har et sylindrisk avsnitt 56 med et dempelegeme 57, et tappformet hus 60 for en ikke vist forsterkningsladning tilsvarende dellengden 52 og en konisk anslags-krave 62 med en hekksidig konisk tapp 64 tilsvarende den ytre dellengde 54. The bottom fire tube 2 has a cylindrical section 56 with a damping body 57, a pin-shaped housing 60 for a reinforcing charge, not shown, corresponding to the part length 52 and a conical stop collar 62 with a stern-side conical pin 64 corresponding to the outer part length 54.
Anslagskraven 62 og tappen 64 ligger inne i drivladningshylsen 4, hvor den løse ladning 66 ligger i ladningsrommet 68, altså utenfor splintmantelen 24. Ladningen 66 utfyller hele ladningsrommet 68. The stop collar 62 and the pin 64 are inside the propellant charge sleeve 4, where the loose charge 66 is located in the charge space 68, i.e. outside the splinter jacket 24. The charge 66 fills the entire charge space 68.
Utsparingen eller rommet 16 er fylt med en sprengladning 70. På hekksiden har sprengladningen 70 en boring 74. Denne boring ligger i en avstand 76 fra splintmantelens 24 ende 36. The recess or space 16 is filled with an explosive charge 70. On the stern side, the explosive charge 70 has a bore 74. This bore is at a distance 76 from the end 36 of the splinter jacket 24.
Det viste utførelseseksempel viser det foran nevnte tredje alternativ, nemlig et ballistisk splintprosjektil 1 med en vesentlig øket sprengstoffandel 70 med bibehold av de vanlige tykkelser i prosjektilspissen (gjennomslagskjernen 12) og for splintmantelveggen 24. The design example shown shows the aforementioned third alternative, namely a ballistic shrapnel projectile 1 with a significantly increased explosive content 70 while maintaining the usual thicknesses in the projectile tip (impact core 12) and for the shrapnel jacket wall 24.
Gjennomtrengningseffekten til gjennomslagskjernen 12 oppnås for flystrukturer og lett pansrede kjøretøyer som følge av den lange sprengladning 70. Den til gjennomslagskjernen 12 overførte sprengladningsimpuls er vesentlig større enn ifølge kjent teknikk. Også splintvirkningen er vesentlig større. The penetration effect of the penetration core 12 is achieved for aircraft structures and lightly armored vehicles as a result of the long explosive charge 70. The explosive charge impulse transmitted to the penetration core 12 is significantly greater than according to known technology. The splintering effect is also significantly greater.
Sprengstoffutstrekningen med hensyn på splintmantelen 24 er vesentlig større enn i den kjente teknikk. The extent of the explosive with respect to the splinter jacket 24 is substantially greater than in the known technique.
Den ved granatbunnen gjennomførte tenning medfører at splintene får en større hastighet enn ved en sentral tenning av sprengladningen 70. Denne hastighet frem-kommer som en summering av prosjektilhastighet og den sprengstoffbetingede splinthastighet. Tenningen i granatbunnen har altså en dobbelt fordel. The ignition carried out at the base of the grenade results in the shrapnel gaining a greater speed than with a central ignition of the explosive charge 70. This speed appears as a summation of the projectile speed and the explosive-related shrapnel speed. The ignition in the grenade base thus has a double advantage.
