Description
Foreligende oppfinnelse vedrører en røyksats med tennsats/spreng-sats i en granatboks som initieres fra en tennmekanisme gjennom en forsinkelsesladning. The present invention relates to a smoke charge with an ignition charge/explosive charge in a grenade box which is initiated from an ignition mechanism through a delay charge.
Det er tidligere kjent røykhåndgranater som består av en hylse There are previously known smoke hand grenades which consist of a sleeve
som inneholder en brennbar masse. Massen er normalt rødt fosfor. Ved utkasting initieres massen ved en initiator og antennelsen which contains a combustible mass. The mass is normally red phosphorus. During ejection, the mass is initiated by an initiator and the ignition
kan eventuelt forsinkes ved en forsinkerladning som er plassert mellom initiator og brennbar røykmasse. can possibly be delayed by a retarder charge which is placed between the initiator and combustible smoke mass.
En alvorlig ulempe ved den ovenfor beskrevne type røykhånd-granater er at forbrenningen av den kompakte røykavgivende massen er sterkt eksoterm, og da den foregår innenfor et sterkt begrenset område gir dette opphav til et såkalt "varmeløft". A serious disadvantage of the type of smoke hand grenades described above is that the combustion of the compact smoke-emitting mass is strongly exothermic, and as it takes place within a very limited area, this gives rise to a so-called "heat lift".
Dette fører til at røyken stiger raskt til værs under og etter forbrenningen. Dette fører til at den ønskede effektive skjerming av personell, våpen eller kjøretøyer ikke oppnåes. This causes the smoke to rise quickly into the air during and after the combustion. This means that the desired effective shielding of personnel, weapons or vehicles is not achieved.
Formålet for foreliggende oppfinnelse er derfor å overvinne The purpose of the present invention is therefore to overcome
denne alvorlige svakheten. this serious weakness.
Ifølge foreliggende oppfinnelse løses oppgaven ved at røyksat- According to the present invention, the task is solved by smoke sat-
sen er oppbygget av påhverandre liggende pressede, kompakte, lettantennelige røyksats-skiver og at tennsats/sprengsatsen er anordnet gjennom sentrale hull i disse. then is made up of compressed, compact, easily ignited smoke set discs lying on top of each other and that the igniter set/explosive set is arranged through central holes in these.
på i og for seg kjent måte initieres tennsatsen fra en forsinkerladning. Denne har gjerne en brenntid på-ca. 1,3 in a manner known per se, the ignition charge is initiated from a delay charge. This usually has a burning time of approx. 1.3
sekunder. Forsinkelsesladningen initieres igjen fra en tennhette som avsettes ved en slaghammer som er festet til seconds. The delay charge is again initiated from a firing cap which is deposited by a percussion hammer attached to it
en sikringsarm. Før bruk er sikringsarmen sikret ved en splint som kan trekkes ut. a safety arm. Before use, the safety arm is secured by a cotter pin that can be pulled out.
Til forskjell fra den tidligere kjente type røykhåndgranater med en passiv røyksats vil ved antennelsen av røykhåndgranaten ifølge foreliggende oppfinnelse røykskivene kastes f ra hverandre, og samtidig med at de antennes, rives opp av tenn-/spreng-ladningen. Forbrenningen av røyksatsen finner derfor ifølge foreliggende oppfinnelse sted over et stort område i motsetning til røyk-satsen i tidligere kjente røykhåndgranater. Herved oppnås en langt lavere lokal oppvarming på grunn av den eksoterme reaksjon da mer luft får innvirke som kjølemedium under forbrenningen. På denne måten oppnår man som ønsket å unngå tidligere omtalte "varmeløft" hvorved den dannede røyken blir liggende ned mot bakken slik at man derved får den tilsiktede effektive skjerming. Foreliggende oppfinnelse gir således et verdifullt bidrag til teknikkens stand og kan ikke betraktes som nærliggende i lys av tidligere kjente håndgranater. In contrast to the previously known type of smoke hand grenades with a passive smoke charge, when the smoke hand grenade according to the present invention is ignited, the smoke discs are thrown apart, and at the same time as they are ignited, are torn up by the ignition/explosive charge. According to the present invention, the combustion of the smoke charge therefore takes place over a large area in contrast to the smoke charge in previously known smoke hand grenades. This results in a far lower local heating due to the exothermic reaction as more air is allowed to act as a cooling medium during combustion. In this way, one achieves what one wanted to avoid the previously mentioned "heat lift", whereby the formed smoke lies down towards the ground so that one thereby obtains the intended effective shielding. The present invention thus makes a valuable contribution to the state of the art and cannot be considered close in light of previously known hand grenades.
Oppfinnelsen eksemplifieres og belyses ved den vedlagte teg- The invention is exemplified and illustrated by the attached drawing
ning som viser et snitt gjennom en røykhåndgranat ifølge oppfinnelsen: Tegningen viser et snitt gjennom en utførelsesform av røyk-håndgranaten ifølge oppfinnelsen. På denne er en slaghammer 1 festet på en fjær. Slaghammeren 1 holdes tilbake av sikringsarmen 7. En tennhette 2 er anbrakt over en forsinkelsesladning 3. Under forsinkelsesladningen 4 er en tennsats 8" anordnet som kan være av svartkrutt og som ligger i en aluminiumshylse 9. Denne er omgitt av røyksatsen 5 bestående av pressede røykskiver som utad er avgrenset av granatboksen 4. Over røyksatsen 5 mot tennmekanismen ligger en isoporring ning showing a section through a smoke hand grenade according to the invention: The drawing shows a section through an embodiment of the smoke hand grenade according to the invention. On this, an impact hammer 1 is attached to a spring. The impact hammer 1 is held back by the safety arm 7. An ignition cap 2 is placed over a delay charge 3. Under the delay charge 4, an ignition set 8" is arranged which can be of black powder and which is located in an aluminum sleeve 9. This is surrounded by the smoke set 5 consisting of pressed smoke discs which is bounded on the outside by the grenade box 4. Above the smoke kit 5 towards the ignition mechanism is a polystyrene ring
6. Sikringsarmen er sikret ved en sikringssplint 10. 6. The safety arm is secured by a safety pin 10.
Røykgranaten armeres ved at sikringssplinten 10 trekkes ut. The smoke grenade is armed by pulling out the safety pin 10.
Man holder derunder sikringsarmen 7 presset inn mot granatboksen 4. Når granaten så kastes, vil sikringsarmen 7 kastes av på grunn av slaghammeren 1 som vil gjøre en omskrivende bevegelse om opphengningfjærens akse og treffe tennhetten 2. Derved antennes tennhetten 2 som igjen antenner forsinkelsesladningen 3. Forsinkelsesladningen har en brenntid på ca. Underneath, the safety arm 7 is pressed against the grenade box 4. When the grenade is then thrown, the safety arm 7 will be thrown off due to the impact hammer 1 which will make a circumscribing movement around the axis of the suspension spring and hit the firing cap 2. This ignites the firing cap 2 which in turn ignites the delay charge 3. The delay charge has a burning time of approx.
1,3 sekunder. Etter denne gjennombrenningstiden antennes tennsatsen 8. Denne slår gjennom aluminiumshylsen 9 og antenner derved røyksatsen 5. Ved antennelsen av røyksatsen 5 som består av pressede skiver rives samtidig granatboksen 1.3 seconds. After this burn-through time, the igniter pack 8 is ignited. This punches through the aluminum sleeve 9 and thereby ignites the smoke pack 5. When the smoke pack 5, which consists of pressed discs, is ignited, the grenade box is simultaneously torn
4 opp og røykskivene spres under fragmentering og forbrenning til røyk over det ønskede området. Grunnet fragmen-teringen og spredningen vil ikke en uønsket lokal sterk oppvarming ("varmeløft") inntreffe, men røykskivene vil ved forbrenning gi et hensiktsmessig og tilstrekkelig lavtliggende 4 up and the smoke discs are dispersed during fragmentation and combustion into smoke over the desired area. Due to the fragmentation and dispersion, an unwanted local strong heating ("heat lift") will not occur, but the smoke disks will, upon combustion, produce an appropriate and sufficiently low-lying
brett røykteppet som gir en meget effektiv skjerming. fold the smoke curtain which provides a very effective shielding.
