Description
Foreliggende oppfinnelse angår en projektil-hylse-forbindelse for ammunisjon, spesielt opplosende ovelsesammunisjon med kunststoffmantel, for hurtigskytende skyts, hvor en endedel av et projektil er anbragt i halsen av en hylse. The present invention relates to a projectile-casing connection for ammunition, in particular dissolving ammunition with a plastic jacket, for rapid-firing ammunition, where an end part of a projectile is placed in the neck of a casing.
Opplosende ovelsesammunisjon er. ammunisjon som i likhet med normal ammunisjon kan tilfores en hurtigskytende kanon, som kan avfyres i automatisk skyts og som etter å ha forlatt lopet opploses innenfor en liten skuddvisse. Projektilet av slik ammunisjon har vanligvis en plastmantel som er fylt med en eller flere sammenpressede jernpulverkjerner, lost jernpulver eller en.kombinasjon derav, Dissolving training ammunition is. ammunition which, like normal ammunition, can be fed to a rapid-firing cannon, which can be fired in automatic fire and which, after leaving the barrel, dissolves within a small range of shots. The projectile of such ammunition usually has a plastic jacket which is filled with one or more compressed iron powder cores, loose iron powder or a combination thereof,
hvilken fylling opploses av rotasjonskreftene. which filling is dissolved by the rotational forces.
Ved den stadig okende avfyringshastighet av hurtigskytende kanoner blir det stadig satt hoyere krav til ammunisjonen. Patronene blir ved slik skyts tilfort kammeret med stor hastighet, hvorved det forst opptrer en hoy akselerasjon og deretter en sterk retardasjon i det oyeblikk patronen er kommet inn i kammeret. Dette forårsaker meget hoye påkjenninger på projektilet, i hylsen og ved projektil-hylse-forbindelsen. With the ever-increasing firing rate of fast-firing cannons, ever higher demands are placed on the ammunition. When fired in this way, the cartridges are fed into the chamber at high speed, whereby a high acceleration first occurs and then a strong deceleration at the moment the cartridge has entered the chamber. This causes very high stresses on the projectile, in the sleeve and at the projectile-sleeve connection.
Ved hurtigskytende kanoner blir projektil-hylse-forbindelsen sterkt påkjent av massetreghetskreftene som opptrer ved det nevnte tilforselsforlop. Massetreghetskreftene er bl.a. avhengig av projektil-massen og kanonens skytehastighet, d.v.s. av den opptredende akselerasjon henholdsvis retardasjon. Ved okende kaliberstorrelse oker forholdet av projektiImassen til patronkaliberen, hvorved massetreghetskreftene blir stadig mer kritisk for projektil-hylse-forbindelsen. Som folge herav egner de kjente forekommende projektil-hylse-forbindelser seg ikke for mange hurtigskytende kanoner. In the case of fast-firing guns, the projectile-casing connection is heavily stressed by the mass inertial forces that occur during the aforementioned feeding process. The forces of mass inertia are i.a. depending on the projectile mass and the gun's firing rate, i.e. of the occurring acceleration or deceleration. With increasing caliber size, the ratio of the projectile mass to the cartridge caliber increases, whereby the mass inertial forces become increasingly critical for the projectile-casing connection. As a result, the known projectile-casing connections are not suitable for many fast-firing guns.
Fra US. patentskrift 1.470.591 (fig. 2) er det kjent en projektil-hylse-forbindelse for skarp ammunisjon, hvor tetningsmidlet består av en^ijinacl umbuTckVt del av hylseveggen som griper inn i .en From the US. patent document 1,470,591 (fig. 2), a projectile-casing connection for live ammunition is known, where the sealing means consists of a thin section of the casing wall that engages in
-ringformet utsparing i metall-projektil-veggen. - annular recess in the metal projectile wall.
Ved avfyring blir denne ombukkede muffe på hylseveggen elastisk deformet under virkningen av gasstrykket, hvorved muffen trykkes mot den bakre ende av projektilet for å hindre at forbrenningsgassene skal unnslippe langs utsiden av projektilet. When fired, this bent sleeve on the sleeve wall is elastically deformed under the effect of the gas pressure, whereby the sleeve is pressed against the rear end of the projectile to prevent the combustion gases from escaping along the outside of the projectile.
En slik metallhylse med innad ombukket kant fordrer imidlertid en spesiell fremstillingsoperasjon. Projektilet må trykkes inri i hylsehalsen med en viss kraft inntil vulsten, dannet av den innad ombukkede del av hylsen smetter inn i den ringformede utsparing. However, such a metal sleeve with an inwardly bent edge requires a special manufacturing operation. The projectile must be pressed into the sleeve neck with a certain force until the bead, formed by the inwardly bent part of the sleeve, slips into the annular recess.
For opplosende ammunisjon, hvor projektilet har en forholdsvis myk, plastisk deformerbar plastmantel, er en slik festemåte i en hylse-munning lite egnet. Ikke desto mindre er en god befestigelse av den bakre ende av projektilet i hyls^munningen av stor betydning. For disintegrating ammunition, where the projectile has a relatively soft, plastically deformable plastic jacket, such a method of attachment in a sleeve mouth is not suitable. Nevertheless, a good attachment of the rear end of the projectile in the casing mouth is of great importance.
Foreliggende oppfinnelse går ut på å lose denne oppgave. I denne hensikt er det i henhold til oppfinnelsen foreslått en projektii-hylse-forbindelse av den innledningsvis nevnte art, hvor det i rommet mellom utsparingen i projektilets endedel og den koniske skulder i hylseveggen er anordnet et sikringsmiddel, hvor det særegne ved oppfinnelsen består i at sikringsmidlet er fremstilt av et flytende, etter herding ikke plastisk deformerbart material. Spesielt fordelaktig er det når sikringsmidlet er fremstilt av et stopbart, selvherdende plastmaterial. Denne plast-sikringsring hefter sterkere til den indre vegg i hylsen enn til halsen på projektilet og forblir sittende på hylseveggen under avfyringen, mens den nedre kant på projektilet deformeres radialt for å loses fra sikringsringen. The present invention aims to solve this task. To this end, according to the invention, a projectile-sleeve connection of the type mentioned at the outset is proposed, where a securing means is arranged in the space between the recess in the end part of the projectile and the conical shoulder in the sleeve wall, where the peculiarity of the invention consists in that the securing agent is made from a liquid, non-plastically deformable material after hardening. It is particularly advantageous when the securing means is made of a stoppable, self-hardening plastic material. This plastic safety ring adheres more strongly to the inner wall of the sleeve than to the neck of the projectile and remains seated on the sleeve wall during firing, while the lower edge of the projectile deforms radially to be released from the safety ring.
For nærmere forklaring av forbindelsen vil denne bli beskrevet under henvisning til den medfblgende tegning som viser et utforelses-eksempel av en projektil-hylse-forbindelse. For a more detailed explanation of the connection, this will be described with reference to the accompanying drawing which shows an exemplary embodiment of a projectile-sleeve connection.
Figuren på tegningen viser et aksialt tverrsnitt gjennom en projektil-hylse-forbindelse med inngrepsmidler av et stopbart, selvherdende stoff. The figure in the drawing shows an axial cross-section through a projectile-sleeve connection with engagement means of a stoppable, self-hardening substance.
I henhold til figuren er den nedre del av et projektil 1 innfort According to the figure, the lower part of a projectile 1 is inserted
i halsen 2 av en hylse. Bunndelen av projektilet oppviser en utsparing 5. Rommet mellom skulderen 3 av hylsen og utsparingen 5 er utfylt med flytende, selvherdende kunstharpiks eller klebestoff 6. Dette blir for projektilet innfores i halsen av hylsen helt på en in the neck 2 of a sleeve. The bottom part of the projectile has a recess 5. The space between the shoulder 3 of the sleeve and the recess 5 is filled with liquid, self-hardening synthetic resin or adhesive 6. This is for the projectile to be inserted into the neck of the sleeve completely on a
på forhånd i hylsen anbragt tildekningsplate 7, f.eks. filt. Deretter blir projektilet trykket inn i halsen og patronen med projektilet vendes om. Den ennu klebende harpiks eller klebestoff kan nu lett stromme mellom hylsemantelen og utsparingen 5 og herdes der. cover plate 7 previously placed in the sleeve, e.g. felt. The projectile is then pressed into the throat and the cartridge with the projectile is turned over. The still adhesive resin or adhesive can now easily flow between the sleeve jacket and the recess 5 and harden there.
En ytterligere fordel ved denne utforelsesform er at det oppnås A further advantage of this embodiment is that it is achieved
en storre stivhet mot tverrpåkjenninger. greater stiffness against transverse stresses.
Selv om ovenfor beskrevne projektil-hylse-forbindelse spesielt er bestemt for opplosbare ovelsepatroner, kan det også anvendes ved Although the projectile-casing connection described above is especially intended for dissolvable cartridges, it can also be used in
andre patrontyper. other cartridge types.
