Description
Når man skal anvende røkammunisjon i militær sammenheng for When using smoke ammunition in a military context for
å skaffe en avskjermning av et begrenset eller utstrakt terreng-avsnitt, innebærer ønsket om en tilfredsstillende virkning i visse henseender krav som har vist seg vanskelige eller umulige å forene. Således krever man med forskjellig prioritet dels at avskjermningen skal oppnås raskt, og dels at effekten skal ha en varighet som ofte bør strekke seg over ett, eventuelt flere minutter. to obtain a shielding of a limited or extended section of terrain, the desire for a satisfactory effect in certain respects entails requirements which have proved difficult or impossible to reconcile. Thus, with different priorities, it is required that the shielding must be achieved quickly, and that the effect must have a duration that should often extend over one, possibly several minutes.
Rask avskjermningseffekt har kunnet oppnås med røkammunisjon A rapid shielding effect has been achieved with smoke ammunition
hvor hele røksatsen bringes til virkning ved sprengning (såkalt momentan røkammunisjon). Varigheten av slike avskjermninger er imidlertid sterkt avhengig av vindens hastighet og retning i forhold til siktelinjen mellom fienden og den egne styrke. Varigheten kan under gunstige betingelser andra til ca. 30 s. Ved tversgående vind innskrenker effekttiden seg til noen få sekunder. Røksatser for ammunisjon av denne art er f.eks. fosfor og titantetraklorid eller en sats som angitt i svensk patentskrift nr. 300 773.. where the entire smoke charge is brought into effect by detonation (so-called instantaneous smoke ammunition). However, the duration of such screenings is strongly dependent on the speed and direction of the wind in relation to the line of sight between the enemy and one's own force. Under favorable conditions, the duration can change to approx. 30 s. In crosswinds, the effect time is reduced to a few seconds. Smoke rates for ammunition of this type are e.g. phosphorus and titanium tetrachloride or a rate as stated in Swedish patent document no. 300 773..
For visse anvendelser er denne raske effekt med kort varighet helt fyldestgjørende, mens man ved andre anvendelser stadig ønsker at skjermningen skal sette inn raskt, men også skal ha en garantert varighet av ett eller flere minutter. For certain applications, this quick effect with a short duration is completely adequate, while for other applications you still want the shielding to set in quickly, but also to have a guaranteed duration of one or more minutes.
Varig røklegning oppnås erfaringsmessig best ved at man for-brenner en røksats av såkalt brennende type som ved forbrenningen frembringer en mengde aerosolpartikler pr. tidsenhet tilstrekkelig for skjermningseffekten. Forbrenningsdistansen hos satsen i kombinasjon med dennes forbrenningshastighet gir varigheten av røkut-viklingen-. Røkammunisjon-av denne type er helt tilfredsstillende ved anvendelser hvor der ikke stilles krav om rask belegning og hoved-vekten ligger på maksimal røkeffekt, dvs. stor avskjermningsbredde og lang varighet. Røksatser for ammunisjon av denne type er såkalt HC-sats, dvs. sats bestående av heksakloretan, zinkoksyd og aluminium, og dermed jevnførbare satser, f.eks. som angitt i svensk patentskrift 359 289. According to experience, permanent smoke laying is best achieved by burning a batch of smoke of the so-called burning type, which during combustion produces a quantity of aerosol particles per unit of time sufficient for the shielding effect. The combustion distance of the batch in combination with its combustion speed gives the duration of the smoke-out winding. Smoke ammunition of this type is completely satisfactory in applications where there is no requirement for rapid coating and the main emphasis is on maximum smoke effect, i.e. large shielding width and long duration. Smoke rates for ammunition of this type are so-called HC rates, i.e. rates consisting of hexachloroethane, zinc oxide and aluminium, and thus comparable rates, e.g. as stated in Swedish patent document 359 289.
Ved visse anvendelser finnes der imidlertid som tidligere nevnt et taktisk behov for en kombinasjon av rask innsats og viss In certain applications, however, as previously mentioned, there is a tactical need for a combination of quick effort and certainty
garantert varighet. Dette krav er særlig utpreget ved kortholds-ammunisjon, f.eks. røkhåndgranater, geværrøkgranater og ved visse direkte skytende våpen. guaranteed duration. This requirement is particularly pronounced for short-range ammunition, e.g. smoke hand grenades, rifle smoke grenades and in the case of certain direct-fire weapons.
For å oppnå en viss forbedring av ammunisjon som primært er bestemt for god varighet, har man i slik ammunisjon innført satser med forskjellig brennhastighet. Ved at der først i en kortere tid forbrukes en sats med maksimal brennhastighet og siden for resten av tiden brennes en sats med normal brennhastighet, har man til en viss grad kunnet etterkomme kravet om rask innsats. Prinsippet har dog en begrensning ved at en økning av satsens brennhastighet bare har kunnet oppnås med tilsetninger som medfører at røkeffekten pr. vektenhet blir redusert i påtagelig grad. In order to achieve a certain improvement in ammunition which is primarily intended for good duration, rates with different rates of fire have been introduced in such ammunition. By first consuming a batch with maximum burning speed for a shorter period of time and then burning a batch with normal burning speed for the rest of the time, it has been possible to some extent to comply with the requirement for quick effort. However, the principle has a limitation in that an increase in the batch's burning rate has only been achieved with additions which mean that the smoke effect per weight unit is reduced to a noticeable extent.
Den foreliggende oppfinnelse går således ut på en røkammuni-sjon som samtidig gir både rask og langvarig avskjermningseffekt, The present invention is thus based on a smoke ammunition which at the same time provides both a quick and long-lasting shielding effect,
dvs. gir en røkproduksjon som både inntrer raskt og er varig, samtidig som røkkroppen utgjøres av fast røksats av såkalt brennende type. Den ønskede effekt oppnås ved at røkammunisjonen i henhold til oppfinnelsen har kjennetegn som angitt i patentkravene. i.e. produces a smoke production that both sets in quickly and is long-lasting, at the same time that the smoke body is made up of a fixed batch of so-called burning type smoke. The desired effect is achieved by the fact that the smoke ammunition according to the invention has characteristics as stated in the patent claims.
En utvikling av såvel momentan som kontinuerlig røk oppnås ved at røklegemet er oppdelt i en hurtigdel og en varighetsdel innen ett og samme hylster, og at hurtlgdelen har høyere brennhastighet enn varighetsdelen til tross for at roan har samme eller bare innen rammen av fullgod røkeffekt variert sammensetning i såvel hurtigdel som varighetsdel. Økningen av brennhastigheten 1 hurtlgdelen oppnås ved hjelp av en øket brennflate. Ved en foretrukken utførelsesform er brennflaten innrettet til å holde seg hovedsakelig konstant under hele forbrenningen. A development of both instantaneous and continuous smoke is achieved by the fact that the smoke body is divided into a rapid part and a permanent part within one and the same casing, and that the rapid part has a higher burning speed than the permanent part despite the fact that the roan has the same or only within the framework of a full smoke effect varied composition in both the quick part and the duration part. The increase in the burning speed in the immediate part is achieved by means of an increased burning surface. In a preferred embodiment, the burning surface is arranged to remain substantially constant throughout the combustion.
Den raske røkeffekt kan således oppnås ved at der forbrennes The rapid smoke effect can thus be achieved by combustion
et antall mindre røklegemer som har en eller flere flater helt eller nesten eksponert for antennelse. Der kan være anordnet a number of smaller smoke bodies that have one or more surfaces completely or nearly exposed to ignition. There may be arranged
organer til samtidig antennelse av legemene. Med dette arrangement er. det mulig under utnyttelse av en med hensyn til røkeffektivitet fullgod sats å avbrenne en stor mengde røksats under en kortvarig første, fase. Varighetslegemet antennes samtidig med hurtigdelen. organs for simultaneous ignition of the bodies. With this arrangement is. it is possible to burn off a large amount of smoke during a short-term first phase using a rate that is satisfactory in terms of smoke efficiency. The duration body is ignited at the same time as the quick part.
Dens røksats-avbrenning er fortrinnsvis -lineært jevn ved at dette legeme bare eksponerer en av flatene. Its smoke batch combustion is preferably -linearly uniform in that this body only exposes one of the surfaces.
Ved hjelp av oppfinnelsen ér det mulig å tilgodese skiftende krav i en utstrekning som ikke oppnås med tidligere kjente anord-ninger. Således er det. mulig-å velge dé følgende egenskaper fritt og hver for seg rett og slett ved formgivning: Kvantitiet av røk totalt under hurtigrøkfasen. Den styres ved hjelp av hele det volum av røksatsbeholderen som avdeles for denne del; - kvantitet av røk pr. tidsenhet såvel som varighet av hurtig-røksfasen. Disse styres ved formgivning av de enkelte legemer og/eller ved antall legemer; With the help of the invention, it is possible to meet changing requirements to an extent that is not achieved with previously known devices. Thus it is. possible-to choose the following properties freely and individually simply by designing: The quantity of smoke in total during the rapid smoking phase. It is controlled by using the entire volume of the smoke batch container allocated for this part; - quantity of smoke per unit of time as well as duration of the fast smoke phase. These are controlled by the design of the individual bodies and/or by the number of bodies;
fordelingen av røkutviklingen under hurtigrøksfasen, styrt ved valg av de enkelte legemers geometri. Således gir et massivt sylindrisk legeme en sterkt avtagende brennflate og dermed sterkt avtagende røkproduksjon. Et sylindrisk legeme med et the distribution of the smoke development during the rapid smoke phase, controlled by the choice of the geometry of the individual bodies. Thus, a massive cylindrical body provides a greatly reduced burning surface and thus greatly reduced smoke production. A cylindrical body with a
gjennomgående hull gir en svakt avtagende brennflate. Også andre former er selvsagt tenkelige og realiserbare; through holes provide a slightly decreasing burning surface. Other forms are of course conceivable and realizable;
varigheten av varighetsdelen, styrt av dette legemes lengde; the duration of the duration part, governed by the length of this body;
røkutviklingen pr. tidsenhet hos varighetsdelen, styrt av avbrent kvantitet pr. tidsenhet, som i sin tur beror på brennende flate og brennhastighet, hvorav den sistnevnte egenskap forutsettes å varieres bare innen de snevre grenser som gir fullgod røkeffekt pr. vektenhet. smoke development per unit of time for the duration part, governed by the quantity burned per unit of time, which in turn depends on the burning surface and burning speed, of which the latter property is assumed to be varied only within the narrow limits that give a good smoke effect per weight unit.
Mellom hurtlgdelen og varighetsdelen anbringes kruttskikt, f.eks. svartkrutt, for antennelse av røksatsen. Likeledes kan der være anordnet kruttskikt mellom enkeltlegemene i hurtlgdelen og ovenpå den fra varighetsdelen bortvendte side av hurtlgdelen, hvor-ved der fås mer intens antennelseseffekt. A layer of gunpowder, e.g. black powder, for igniting the smoke batch. Likewise, a layer of gunpowder can be arranged between the individual bodies in the fuse part and on top of the side of the fuse part facing away from the duration part, where a more intense ignition effect is obtained.
Hurtigrøkdelen har hensiktsmessig en effekttid av 2-20 s, fortrinnsvis 5-15 s, mens varighetsdelen fortrinnsvis har en effekttid av 0,5-6 min, fortrinnsvis 1-3 min. The quick smoke part conveniently has an effect time of 2-20 s, preferably 5-15 s, while the duration part preferably has an effect time of 0.5-6 min, preferably 1-3 min.
Oppfinnelsen vil nå bli belyst nærmere under henvisning til The invention will now be explained in more detail with reference to
tegningen. the drawing.
Fig. 1 viser lengdesnitt av en røkgranat ifølge en første ut-førelsesform for oppfinnelsen, oppbygget av en hurtigrøkdel og en varighetsrøkdel. Fig. 1 shows a longitudinal section of a smoke grenade according to a first embodiment of the invention, made up of a quick smoke part and a duration smoke part.
Fig. 2 viser snitt etter linjen II-H på fig. 1. Fig. 2 shows a section along the line II-H in fig. 1.
Fig. 3 viser lengdesnitt av en annen utførelsesform for en røkgranat ifølge oppfinnelsen. Fig. 1 viser en røkgranat med en hurtigdel 10 og en varighetsdel 11 innesluttet i en felles hylse 12 og bestående av røksats av samme sammensetning. Mellom hurtigdelen 10 og varighetsdelen 11 er der anbragt et touttskikt ,13. Hurtigdelen 10 er oppbygget av fire sylindriske legemer 10a-d anordnet konsentrisk omkring et tennorgan 14. I bunnen av det rom 15 som dannes mellom sylinderlegemene 10a-d, er der innlagt en forsterkningspille 16 av krutt. Ved avfyring ved hjelp av tennorganet 14 antennes kruttskiktet 13 og kruttpillen 16, og disse antenner da alle røksatslegemene 10a-d samtidig og momentant. Også varighetsdelen 11 blir antent ved avfyringen, men røksatsav-brenningen skjer her langsommere og med avtagende styrke. Fig. 3 shows a longitudinal section of another embodiment of a smoke grenade according to the invention. Fig. 1 shows a smoke grenade with a rapid part 10 and a duration part 11 enclosed in a common sleeve 12 and consisting of a smoke charge of the same composition. Between the fast part 10 and the duration part 11, a tout layer 13 is placed. The quick section 10 is made up of four cylindrical bodies 10a-d arranged concentrically around an ignition device 14. In the bottom of the space 15 that is formed between the cylindrical bodies 10a-d, a reinforcing pill 16 of gunpowder is inserted. When fired using the igniter 14, the powder layer 13 and the powder pellet 16 are ignited, and these then ignite all the smoke batch bodies 10a-d simultaneously and instantaneously. The duration part 11 is also ignited during the firing, but the smoke-sav burning takes place here more slowly and with decreasing strength.
Røkammunisjonen på fig.3 er oppbygget av en hurtigdel 17 og en varighetsdel 18. Hurtigdelen 17 består av to over hinannen liggende røksatssylindre 17a, 17b med sentralt hull 19 og pressede kruttskikt 20a, b, c mellom sylindrene, mellom hurtigdel og varighetsdel og ovenpå røksatssylinderen 17a. I senterhullet 19 er der anordnet et avfyringsorgan 21. Ved avfyring med organet 21 antennes kruttskiktene 20a, b, c, som i sin tur antenner røksatsen. Den økede brennflate i hurtigdelen 17 medfører at hurtigdelen blir antent momentant og avbrenner raskere enn varighetsdelen 18, til tross for at de to deler 17 og 18 utgjøres av røksats av samme sammensetning. The smoke ammunition in fig.3 is made up of a rapid part 17 and a duration part 18. The rapid part 17 consists of two smoke charge cylinders 17a, 17b lying one above the other with a central hole 19 and pressed gunpowder layers 20a, b, c between the cylinders, between the quick part and the duration part and on top of the smoke charge cylinder 17a. A firing device 21 is arranged in the center hole 19. When firing with the device 21, the gunpowder layers 20a, b, c are ignited, which in turn ignite the smoke charge. The increased burning surface in the rapid part 17 means that the rapid part is ignited momentarily and burns faster than the duration part 18, despite the fact that the two parts 17 and 18 are made up of smoke of the same composition.
