Description
Flatetenner for brennsats. Flat teeth for firing rate.
Det finnes bestemte typer apparater hvori en brennsats må tennes og da helst således at brennprosessen starter på brenn-satsens samlede aksiale utstrekning. Brennsatsen får for dette formål en uttagning hvori en flatetenner innsettes, fordi den ikke bare skal tenne i et meget snevert begrenset område, men på hele flaten. De hittil anvendte flatetennere består van-ligvis av svartkrutt og var følgelig føl-somme mot ytre innvirkninger og hadde også relativt lange tenntider. There are certain types of devices in which a combustion batch must be ignited and preferably in such a way that the combustion process starts on the entire axial extent of the combustion batch. For this purpose, the burner has a recess into which a surface igniter is inserted, because it should not only ignite in a very narrowly limited area, but on the entire surface. The flat igniters used to date usually consist of black powder and were consequently sensitive to external influences and also had relatively long ignition times.
Oppfinnelsen vedrører altså en flatetenner med brennsats til tenning av brenn-og/eller eksplosjonsdyktige stoffer med i den bakre ende av en foran lukket hylse innsatt bunnstykke med en gjennomgående sentral aksial boring som opptar en tennhette og en etterkoblet avfyringsladning og med et gjennom brennsatsen trengende tennrør, som slutter seg til fyringsladnin-gen, og flatetenneren er karakterisert ved at den over hele tennrørets lengde momentant tennbare brennsats er en hurtigbrennende pyroteknisk blanding og hylsen består av et material som er lett opprivbart og/eller ødeleggbart over den samlede flate ved hjelp av gasstrykket, resp. blandingens flammevirkning. På grunn av den meget korte tenntid som bare utgjør ca. The invention thus relates to a flat igniter with a propellant for igniting combustible and/or explosive substances with a bottom piece inserted into the rear end of a sleeve closed at the front with a through central axial bore that accommodates an igniter cap and a subsequent firing charge and with an ignition tube penetrating through the propellant , which joins the firing charge, and the flat igniter is characterized by the fact that the igniter, which can be instantly ignited over the entire length of the igniter tube, is a fast-burning pyrotechnic mixture and the sleeve consists of a material that is easily tearable and/or destructible over the entire surface with the help of the gas pressure , respectively flame action of the mixture. Due to the very short ignition time, which only amounts to approx.
1 msek. eller mindre, tennes nu brennsatsen med en gang over den samlede aksiale utstrekning. For å frembringe en kraftigst mulig tennstråle i hulsylinderen er det hensiktsmessig etter tennhetten dessute nå koble en ekstraladning som gir 1 msec. or less, the combustion rate is now ignited at once over the total axial extent. In order to produce the most powerful ignition beam possible in the hollow cylinder, it is appropriate to connect an additional charge after the ignition cap, which gives
den egentlige tennstråle. Ved den pyrotekniske blandings avbrenning blir patron-mantelen som består av et lett ødeleggbart material med en gang fjernet, således at brennflammen uhindret kommer til brennsatsen. the actual spark. When the pyrotechnic mixture burns, the cartridge jacket, which consists of an easily destructible material, is immediately removed, so that the burning flame reaches the combustion chamber unimpeded.
Som material for hylsen anvendes spe-sielt papir eller kunststoff. Special paper or plastic is used as material for the sleeve.
Den pyrotekniske blanding fremstilles hensiktsmessig av 75 deler bariumnitrat og 25 deler magnesiumpulver eller et pulver av en alummium-magnesiumlegering. The pyrotechnic mixture is suitably prepared from 75 parts of barium nitrate and 25 parts of magnesium powder or a powder of an aluminium-magnesium alloy.
Oppfinnelsen skal forklares nærmere ved hjelp av et på tegningen vist utførel-seseksempel. The invention shall be explained in more detail by means of an embodiment shown in the drawing.
Flatetenneren har form av en patron med det av metall bestående bunnstykke 5 og den eksempelvis av kunststoff bestående oventil lukkede mantel 6. Den nedre sone 7 av mantelen 6 er fortykket og utstyrt med en uttagning som etter påskyvning av mantelen på halsen av bunndelen 5 griper inn i en ringkrave 8. På bunnstykket 5 er det påsatt en skål 9 og på hodet påført en skål 10. Mellom disse to skåler er det innsatt en hulsylinder 3 av et lett ødeleggbart material. Den pyrotekniske blanding er be-tegnet med 4. Den omgir, som man ser, hulsylinderen 3. 1 er tennhetten, 2 en forster-kerladning. The flat igniter has the shape of a cartridge with the bottom piece 5 consisting of metal and the cover 6, for example made of plastic, which is closed at the top. The lower zone 7 of the cover 6 is thickened and equipped with a recess which, after pushing the cover onto the neck of the bottom part 5, engages in a ring collar 8. A bowl 9 is attached to the bottom piece 5 and a bowl 10 is applied to the head. Between these two bowls a hollow cylinder 3 of an easily destructible material is inserted. The pyrotechnic mixture is denoted by 4. It surrounds, as can be seen, the hollow cylinder 3. 1 is the igniter cap, 2 a booster charge.
Ved anvendelsen av flatetenneren tennes tennhetten 1 som på sin side tenner forsterkerladningen 2. Herved gjennom-brytes skålen 9, og tennstrålen trer inn i hulsylinderen 3. Da denne forutsetnings-messig skal være lett å ødelegge, fjernes den på grunn av gasstrykket, resp. flamme-innvirkningen, og nu kan tennstrålen tenne den pyrotekniske blanding 4 slaglignende over hele lengden. Mantelen 6 ødelegges og tennflammen bringes over hele lengden av tennladningen 4 i berøring med brennsatsen. When the flat igniter is used, the igniter cap 1 is ignited, which in turn ignites the booster charge 2. This breaks through the bowl 9, and the ignition jet enters the hollow cylinder 3. As this should be easy to destroy, it is removed due to the gas pressure, resp. the flame impact, and now the ignition beam can ignite the pyrotechnic mixture 4 in a blow-like manner over the entire length. The mantle 6 is destroyed and the ignition flame is brought over the entire length of the ignition charge 4 into contact with the fuel.
