Description
Oppfinnelsen vedrører en avstandsbrannrørinnretning for et prosjektil som inneholder et mekanisk nesebrannrør med vesentlige brannrørdeler, og et avstandsbrannrør utformet som et påsettbart adapter, med et adapterhus utformet som bærer for avstandsbrannrørets funksjonsdeler, og med midler for påsetting på nesebrannrøret. The invention relates to a distance fire tube device for a projectile containing a mechanical nose fire tube with essential fire tube parts, and a distance fire tube designed as an attachable adapter, with an adapter housing designed as a carrier for the distance fire tube's functional parts, and with means for attachment to the nose fire tube.
Ved et kjent avstandsbrannrør av denne type (GB-A 218.586) settes et adapterhus på et anslagsbrannrør. I den fremre enden av dette adapterhus er det et andre anslagsbrannrør som er i stand til å utløse det første, lengre bak anordnede anslagsbrannrør. Med dette avstandsbrannrør er det mulig å kunne tenne prosjektilet i en avstand på eksempelvis 10-50 cm fra målet, alt i avhengighet av adapterhusets lengde. In the case of a known distance fire pipe of this type (GB-A 218,586), an adapter housing is placed on an impact fire pipe. At the forward end of this adapter housing there is a second impact fire tube which is able to trigger the first, further back arranged impact fire tubes. With this distance fire tube, it is possible to ignite the projectile at a distance of, for example, 10-50 cm from the target, all depending on the length of the adapter housing.
Ved et annet kjent avstandsbrannrør av denne type (US-A 3.124.073) forefinnes det et sylindrisk metallhus hvorpå det settes en nese av et isolerende materiale. Til denne nesen er det festet et elektronisk nærhetsbrannrør med en ringformet antenne. Med et slikt brannrør kan prosjektilet tennes så snart det befinner seg i en avstand på eksempelvis 1-15 m fra målet. In another known stand-off fire pipe of this type (US-A 3,124,073), there is a cylindrical metal housing on which a nose of an insulating material is placed. An electronic proximity fire tube with a ring-shaped antenna is attached to this nose. With such a fire tube, the projectile can be ignited as soon as it is at a distance of, for example, 1-15 m from the target.
Det skal også nevnes et ytterligere avstandsbrannrør, som har et elektronisk nærhetsbrannrør, men hvor det må treffes spesielle tiltak for å sikre at det elektroniske nærhets-brannrør ikke bare virker skikkelig i pent vær, og i tørr luft, men også i regnvær. Mention should also be made of a further distance fire hydrant, which has an electronic proximity fire hydrant, but where special measures must be taken to ensure that the electronic proximity fire hydrant not only works properly in good weather and in dry air, but also in rainy weather.
Hensikten med oppfinnelsen er å tilveiebringe et brannrør som etter valg kan virke som anslagsbrannrør eller som nærhets-brannrør, alt etter hvilken funksjon som ønskes. The purpose of the invention is to provide a fire hose which, by choice, can act as an impact fire hose or as a proximity fire hose, depending on which function is desired.
Dette oppnås ifølge oppfinnelsen ved at den innledningsvis nevnte avstandsbrannrørinnretning er utført slik at av-standsbrannrøret er et elektronisk brannrør og innbefatter følgende deler: en avstandsføler med tilhørende beregnings- og tennkretskopling, This is achieved according to the invention by the fact that the distance fire pipe device mentioned at the outset is designed so that the distance fire pipe is an electronic fire pipe and includes the following parts: a distance sensor with associated calculation and ignition circuit coupling,
en elektrisk strømkilde, an electrical current source,
en elektrisk tennkapsel for betjening av en tennstift i nesebrannrøret. an electric igniter capsule for operating a lighter in the nasal fire tube.
De fordeler man oppnår med oppfinnelsen er i hovedsaken at et brannrør med anslags- og forsinkelsesfunksjoner kan omdannes til et avstandsbrannrør ved påsetting av et adapter, eksempelvis i felten, hvorved man oppnår betydelige besparelser, fordi den dyre elektronikk bare anvendes når det er behov for den, dvs.at man ikke benytter den når brannrøret benyttes uten avstandsfunksjon. Videre kan adapteret utføres kort og lett, slik at det praktisk talt ikke har noen innflytelse på prosjektilets ballistiske egenskaper. The advantages achieved with the invention are mainly that a fire hose with impact and delay functions can be converted into a distance fire hose by attaching an adapter, for example in the field, thereby achieving significant savings, because the expensive electronics are only used when there is a need for it , i.e. that it is not used when the fire hose is used without a distance function. Furthermore, the adapter can be made short and light, so that it has practically no influence on the projectile's ballistic properties.
Oppfinnelsen skal forklares nærmere nedenfor under henvisning til tegningen som viser et snitt gjennom en utførelsesform. The invention will be explained in more detail below with reference to the drawing which shows a section through an embodiment.
I et prosjektillegeme 10 er det skrudd inn et nesebrannrør 11 med momentan-(anslag-) og forsinkelsesfunksjoner, med mulighet for omstilling ved hjelp av en koplingsinnretning 12. I spissen for nesebrannrøret 11 er det anordnet en betjeningsknapp 13 som tjener til forskyvning av en tennstift 14. Slike nesebrannrør er kjent og trenger derfor ingen nærmere beskrivelse. Into a projectile body 10 is screwed a nose fire tube 11 with instantaneous (impact) and delay functions, with the possibility of adjustment using a coupling device 12. At the tip of the nose fire tube 11 there is an operating button 13 which serves to move an ignition pin 14. Such nasal fire tubes are known and therefore need no further description.
Ifølge oppfinnelsen er det på nesebrannrøret 11 påsatt og fastgjort et adapter 20 i form av en avstandsbrannrørinn-retning. Et hus 21 inneholder regnet ovenfra og nedover en avstandsføler 22 med tilhørende elektronisk koplingsplate 23, et elektrolyttbatteri med kontaktstift 24, elektrodestabel 25 og elektrolytthus 26 som elektrisk strømkilde for forsyning av avstandsbrannrørinnretningen med den nødvendige elektriske energi. Videre forefinnes en elektrisk fenghette, her eksempelvis en elektrisk gasstrykk-kapsel 27, samt midler for befestigelse av huset 21 på nesebrannrøret 11. Disse midler består her i tre jevnt over omkretsen til nesebrannrøret 11 anordnede stifter 28 som sammen med tilsvarende utsparinger 29 i huset 21 danner en bajonettlås, slik at en ringformet bæreflate 30 i huset 21 kan legge seg godt an mot nese-brannrørets 11 tilspissede overflate. En del 31, som inneholder elektrolytthuset 26 og gasstrykk-kapselen 27, er aksialt forskyvbart anordnet i huset 21.Dette skjer ved hjelp av en sporformet utsparing 32 hvori en i huset 21 festet stift 33 rager inn. En ytterligere ringformet bæreflate 35 på delen 31 bidrar til et fast og godt anlegg mellom adapteret 20 og nesebrannrøret 11. According to the invention, an adapter 20 in the form of a remote fire pipe device is attached and fixed to the nose fire pipe 11. A housing 21 contains, counted from top to bottom, a distance sensor 22 with associated electronic connection plate 23, an electrolyte battery with contact pin 24, electrode stack 25 and electrolyte housing 26 as an electrical current source for supplying the distance fire tube device with the necessary electrical energy. Furthermore, there is an electric catch cap, here for example an electric gas pressure capsule 27, as well as means for attaching the housing 21 to the nasal fire tube 11. These means here consist of three pins 28 arranged evenly over the circumference of the nasal fire tube 11 which together with corresponding recesses 29 in the housing 21 forms a bayonet lock, so that an annular support surface 30 in the housing 21 can fit snugly against the pointed surface of the nose fire pipe 11. A part 31, which contains the electrolyte housing 26 and the gas pressure capsule 27, is axially displaceable arranged in the housing 21. This takes place by means of a groove-shaped recess 32 into which a pin 33 fixed in the housing 21 protrudes. A further ring-shaped support surface 35 on the part 31 contributes to a firm and good connection between the adapter 20 and the nasal fire tube 11.
Den beskrevne avstandsbrannrørinnretning virker på følgende måte: Foreligger det eksempelvis i felten et behov for et avstands-brannrør, så settes et adapter 20 på det til et prosjektil 10 festede nesebrannrør 11 ved hjelp av bajonettlåsen. Avfyr-ingssjokket som oppstår ved avfyringen av prosjektilet, vil bevirke at elektrodestabelen 25 bryter gjennom et på dekselet til elektrolytthuset 26 anbragt beregnet bruddsted 36, hvorved det, sammen med det stasjonære elektrolytthus 26, dannes et aktiverbart elektrolyttbatteri. En tetningsring 34 sørger for at elektrolyttvæsken ikke kan strømme ut i det nå tomme rom. Etter en bestemt aktiveringstid vil det på batteri-polene ligge en spenning for avstands- og tennelek-tronikken. Den elektriske forbindelse kan eksempelvis skje over kontaktstiften og en derpå isolert anbragt kontaktring med tilsvarende kontaktsteder for koplingsplaten. En av-standsføler er kjent type.eksempelvis ifølge DE 25 08 066 C2, DE 24 56 162 C2 eller DE 29 49 521 C2 vil nå kontinuerlig måle avstanden til målet og vil tenne tennmiddelet innenfor en gitt avstand fra målet. Tennmiddelet er i dette tilfelle den elektriske gasstrykkkapsel 27 som tennes over elektriske kontaktbaner 41 og 42 samt kontaktstedene 43 og 44. Gass-trykkapselen 27 vil på sin side påvirke betjeningsknappen 13 i nesebrannrøret og utløse tennstiften 14 og derved prosjek-tiltenningen. The distance fire tube device described works in the following way: If, for example, there is a need in the field for a distance fire tube, then an adapter 20 is placed on the nose fire tube 11 attached to a projectile 10 using the bayonet lock. The firing shock that occurs when the projectile is fired will cause the electrode stack 25 to break through a calculated breaking point 36 placed on the cover of the electrolyte housing 26, whereby, together with the stationary electrolyte housing 26, an activatable electrolyte battery is formed. A sealing ring 34 ensures that the electrolyte liquid cannot flow out into the now empty space. After a certain activation time, there will be a voltage on the battery poles for the distance and ignition electronics. The electrical connection can, for example, take place via the contact pin and a contact ring placed on it in isolation with corresponding contact points for the connection plate. A distance sensor is a known type, for example according to DE 25 08 066 C2, DE 24 56 162 C2 or DE 29 49 521 C2, will now continuously measure the distance to the target and will ignite the incendiary within a given distance from the target. In this case, the ignition means is the electric gas pressure capsule 27 which is ignited over electrical contact paths 41 and 42 as well as the contact points 43 and 44. The gas pressure capsule 27 will in turn affect the operating button 13 in the nasal fire tube and trigger the igniter 14 and thereby the projectile ignition.
Ved at delen 31 kan forskyves i huset 21 er man for adapteret 20 som sådant sikret en bestemt håndterings-, transport og fallsikkerhet. Det er først når adapteret er satt på nese-brannrøret at elektrodehuset 26 blir fastholdt. Selv i denne stilling må imidlertid det beregnede bruddsted 36 brytes ved en kraftpåvirkning for aktivering av batteriet, og man er således også sikret en ladnlngssikkerhet. By the fact that the part 31 can be displaced in the housing 21, the adapter 20 as such is ensured a certain handling, transport and fall safety. It is only when the adapter is placed on the nose fire tube that the electrode housing 26 is secured. Even in this position, however, the calculated breaking point 36 must be broken by a force to activate the battery, and charging safety is thus also ensured.
