Abstract

1. A projectile with a case (3), wherein a through opening (5) in the bottom (4) of the case contains a firing capsule (9) which can be struck from the outside and which fires a tamped propellent charge (7) provided in the interior of the case in a propellent charge cartridge (6), and wherein the propellent charge cartridge (6), the diameter of which is less than that of the projectile (1), has at least one lateral gas outlet opening (8) into a gas pressure chamber (10) of the case (3), characterised in that the propellent charge cartridge (6) is connected to the projectile (1) and has a cartridge bottom (17) which produces the tamping of the propellent charge and which is in contact with the bottom (4) of the case and which is provided with a firing opening (15) which is coaxial with the through opening (5) in the bottom (4) of the case.

Description

Oppfinnelsen vedrører et prosjektil med en hylse, hvor en gjennomgående åpning i hylsebunnen opptar en utenfra anslagbar tennhette, som tenner en inne i hylsen i en drivladningspatron anordnet, demmet drivladning, idet drivladningspatronen, hvis diameter er mindre enn prosjektilets, har minst en sideveis, med en ødeleggbar tildekning forsynt gassutstrømningsåpning mot et ringformet gasstrykkrom i hylsen. The invention relates to a projectile with a sleeve, where a continuous opening in the bottom of the sleeve accommodates an ignition cap that can be struck from the outside, which ignites a contained propellant charge arranged inside the sleeve in a propellant charge cartridge, the propellant charge cartridge, whose diameter is smaller than that of the projectile, has at least one side direction, with a destructible cover provided with a gas outflow opening against an annular gas pressure chamber in the sleeve.

Slike utførelser er eksempelvis kjent i fra AT-PS 371 596 og 374 583. Drivladningspatronen er innsatt i hylsebunnens åpning, og den deri plasserte drivladning dekkes utad med tennhetten. I det i hylsen utformede gasstrykkrom, som er lukket med det innsatte prosjektil, munner det ut flere gassutløpsåpninger som er anordnet sideveis i drivladningspatronen. Når tennhetten påvirkes vil den tenne drivladningen. Drivladningsgassene går inn i gasstrykkrommet, og etter at et tilsvarende trykk har bygget seg opp, vil prosjektilet gå ut av hylsen. Gassutløpsåpningene ligger i en avstand fra drivladningens mot tennhetten grensende brennside og derfor vil de utstrømmende gasser rive med seg drivladningspartikler som således ikke tar del i forbrenningen. Den etter avfyringen i hylsen tydelig erkjennbare andel av drivladningspartikler er relativt stor. Forsøk har vist at dette kan gi variasjoner på 15$ og mer i avfyringshastig-heten, med tilhørende vesentlig reduksjon av treffsikkerheten. Hensikten med foreliggende oppfinnelse er å tilveie-bringe et prosjektil av den innledningsvis nevnte type, hvilket prosjektil er enklere i fremstilling, og hvor det på foretrukken måte ved hjelp av en vesentlig mer fullstendig drivladningsforbrenning kan oppnås en i størst mulig grad konstant utgangshastighet, med tilhørende bedre treffsikker-het . Such designs are known, for example, from AT-PS 371 596 and 374 583. The propellant charge cartridge is inserted into the opening of the sleeve base, and the propellant charge placed therein is covered externally with the ignition cap. In the gas pressure chamber formed in the sleeve, which is closed with the inserted projectile, there are several gas outlet openings which are arranged laterally in the propellant cartridge. When the ignition cap is affected, it will ignite the propellant charge. The propellant gases enter the gas pressure chamber, and after a corresponding pressure has built up, the projectile will exit the casing. The gas outlet openings are located at a distance from the burning side of the propellant charge bordering the igniter cap and therefore the flowing gases will carry with them propellant charge particles which thus do not take part in the combustion. The clearly recognizable proportion of propellant charge particles in the sleeve after firing is relatively large. Experiments have shown that this can produce variations of 15$ and more in the firing speed, with an associated significant reduction in accuracy. The purpose of the present invention is to provide a projectile of the type mentioned at the outset, which projectile is simpler to manufacture, and where, in the preferred way, by means of a significantly more complete propellant charge combustion, a constant output velocity to the greatest possible extent can be achieved, with associated better accuracy.

Ifølge oppfinnelsen foreslås det derfor et prosjektil som nevnt innledningsvis, kjennetegnet ved at drivladningspatronen er forbundet med prosjektilet og har en patronbunn som bevirker demmingen av drivladningen, berører hylsebunnen og har en med den gjennomgående åpning i hylsebunnen koaksial, med en av tennstrålen ødeleggbar tildekning forsynt tennåpning. According to the invention, a projectile is therefore proposed as mentioned at the outset, characterized by the propellant cartridge being connected to the projectile and having a cartridge base which causes the damming of the propellant charge, touches the base of the casing and has an ignition opening coaxial with the through opening in the casing base, with a cover that can be destroyed by the ignition beam .

Fordelaktig kan tennåpningen være mindre enn den gjennomgående åpning i hylsebunnen. Advantageously, the ignition opening can be smaller than the continuous opening in the sleeve base.

Fra den internasjonale patentsøknad, publikasjonsnr. WO 86/05265 er det kjent å ha drivladningen anordnet i en egen hylse som er fast forbundet med prosjektilet. Hylsens gassutstrømningsåpning er koaksial med en i patronbunnen anordnet tennhette. From the international patent application, publication no. WO 86/05265 it is known to have the propellant charge arranged in a separate sleeve which is firmly connected to the projectile. The sleeve's gas outflow opening is coaxial with a firing cap arranged in the cartridge base.

Fra det tyske patent nr. 297.973 er det kjent et prosjektil hvor det i den bakre delen er anordnet et kammer for drivladningen. Kammeret avsluttes bakover av en bunnplate som har tre utstrømningsåpninger. From the German patent no. 297,973, a projectile is known in which a chamber for the propellant charge is arranged in the rear part. The chamber is terminated at the rear by a bottom plate which has three outflow openings.

US-PS 3.776.136 viser et prosjektil hvor det i hylsen er en drivladningspatron. US-PS 3,776,136 shows a projectile in which there is a propelling charge cartridge in the sleeve.

Det nye ved oppfinnelsen, som fremhevet i karakteristikken i det selvstendige krav, er imidlertid ikke kjent fra den her nevnte teknikkens stand. Det man særlig oppnår med oppfinnelsen er en definerbar utgangshastighet. For å oppnå dette er det vesentlig ikke bare å dekke til side-gassutstrømnings-åpningene, men også tennåpningen, for derved å hindre en utfalling av i det minste en del av drivladningen. However, the novelty of the invention, as emphasized in the characteristic in the independent claim, is not known from the state of the art mentioned here. What is particularly achieved with the invention is a definable output speed. In order to achieve this, it is essential not only to cover the side gas outflow openings, but also the ignition opening, thereby preventing at least part of the propellant charge from falling out.

Med oppfinnelsen oppnår man også en fremstillingsfordel, fordi anordningen av drivladningspatronen på prosjektilet forenkler fremstillingen av hylsen. Hylsen, med den lille åpning i hylsebunnen, kan fremstilles i en eneste sponløs arbeidsgang, eksempelvis ved dyptrekking, samtidig som fremstillingen av prosjektilet henholdsvis dets bunndel bare i uvesentlig grad endres i negativ retning. Drivladningspatronen kan fordelaktig skrus inn i en utragende gjengestuss på bunndelen og for dette formål kan drivladningspatronen ha begerform, med yttergjenger. Ved at patronbunnen ligger nær hylsebunnen vil drivgassene hindres i å gå direkte ut gjennom tennåpningen. Det oppstår derfor en sterk oppdemming, helt til brenntverrsnittet har nådd frem til de sideveis gassutløpsåpninger. With the invention, one also achieves a manufacturing advantage, because the arrangement of the propellant cartridge on the projectile simplifies the manufacture of the sleeve. The sleeve, with the small opening in the bottom of the sleeve, can be produced in a single chipless operation, for example by deep drawing, while the production of the projectile or its bottom part is only slightly changed in a negative direction. The propelling charge cartridge can advantageously be screwed into a protruding threaded connection on the bottom part and for this purpose the propelling charge cartridge can be cup-shaped, with external threads. As the cartridge base is close to the sleeve base, the propellant gases will be prevented from escaping directly through the ignition opening. A strong blockage therefore occurs, until the focal cross-section has reached the lateral gas outlet openings.

Oppfinnelsen skal forklares nærmere under henvisning til tegningen, hvor det er vist et utførelseseksempel. The invention shall be explained in more detail with reference to the drawing, where an embodiment example is shown.

Et prosjektil 1, som kan være av en vilkårlig type, eksempelvis en sprenggranat med f orsinkelsesbrannrør eller anslagsbrannrør, en røkgranat, et øvelsesprosjektil osv., er satt inn i en hylse 3. Derved dannes det et gasstrykkrom 10 mellom prosjektilets 1 bunndel 2 og hylsebunnen 4. Prosjektilet 1 har et omkretsspor 11 som gir mulighet for den viste formsluttende forbindelse med et kantområde 12 på hylsen 3. Den formsluttende forbindelse kan skje ved at hylsekanten valses inn eller eksempelvis ved at hylsekanten trykkes punktvis inn i omkretssporet. A projectile 1, which can be of any type, for example an explosive grenade with pre-zincification fire tube or impact fire tube, a smoke grenade, a practice projectile, etc., is inserted into a sleeve 3. Thereby a gas pressure chamber 10 is formed between the bottom part 2 of the projectile 1 and the bottom of the sleeve 4. The projectile 1 has a circumferential groove 11 which allows for the shown shape-locking connection with an edge area 12 on the sleeve 3. The shape-locking connection can be made by rolling the sleeve edge in or, for example, by pressing the sleeve edge pointwise into the circumferential groove.

Hylsen 3 er eksempelvis dyptrukket i en aluminiumlegering og har enn sentral gjennomgående åpning 5 i et bunnområde 16. I denne åpning 5 er det satt inn en tennhette 9. På prosjektilets bunndel 2 er det utformet en gjengestuss 13. Her er en drivladningspatron 6 med tilhørende drivladning 7 satt inn. The sleeve 3 is, for example, deep-drawn in an aluminum alloy and has a central through opening 5 in a bottom area 16. In this opening 5, a firing cap 9 is inserted. A threaded connection 13 is formed on the projectile's bottom part 2. Here is a propellant charge cartridge 6 with associated driving charge 7 inserted.

Som vist har drivladningspatronen i sin bunn 17 en sentral tennåpning 15 med en liten diameter. Videre har drivladningspatronen sideveis gassutløpsåpninger 8 som på innsiden er lukket med en tildekning 14 av et lett ødeleggbart materiale, eksempelvis papir, plast eller lignende. Hensikten med tildekningen er å hindre at drivladningen 7 faller ut. Patronbunnen 17 berører hylsebunnen 4, henholdsvis har maksimalt en som følge av produksjonsunøyaktigheter frem-kommet liten avstand til hylsebunnen. Tennstrålen til den utenfra påvirkede tennhette 9 vil gå gjennom åpningene 5 og 15 og påvirke drivladningen 7. Tildekningen 14 ødelegges. Drivladningen 7 tennes således i tennåpningen 15. Som følge av den meget lille spalt som forefinnes mellom patronbunnen 17 og hylsebunnens 4 område 16 vil det først oppstå en viss oppdemming. Drivgassene som utvikler seg, vil gå ut gjennom gassutløpsåpningene 8 og inn i gasstrykkrommet 10. Drivladningspartikler som rives med av drivgassene fra det indre av drivladningspatronen 6 må derfor passere det brenntverrsnitt som forplanter seg fra tennåpningen 15 og inn i patronen, slik at man derved vil være sikret en fullstendig forbrenning av partiklene. As shown, the propellant charge cartridge has in its bottom 17 a central firing opening 15 with a small diameter. Furthermore, the propellant cartridge has lateral gas outlet openings 8 which are closed on the inside with a cover 14 of an easily destructible material, for example paper, plastic or the like. The purpose of the cover is to prevent the propellant charge 7 from falling out. The cartridge base 17 touches the sleeve base 4, respectively has at most a small distance to the sleeve base resulting from manufacturing inaccuracies. The ignition beam of the externally influenced ignition cap 9 will pass through the openings 5 and 15 and affect the propellant charge 7. The cover 14 is destroyed. The propellant charge 7 is thus ignited in the ignition opening 15. As a result of the very small gap that exists between the cartridge base 17 and the area 16 of the sleeve base 4, a certain damming will first occur. The propellant gases that develop will exit through the gas outlet openings 8 and into the gas pressure chamber 10. Propellant charge particles that are carried along by the propellant gases from the interior of the propellant charge cartridge 6 must therefore pass the focal cross-section that propagates from the ignition opening 15 into the cartridge, so that one will thereby be ensured a complete combustion of the particles.

Den utgangshastighet som et prosjektil 1 ifølge oppfinnelsen får etter at den formsluttende forbindelse 11,12 er brutt, vil bare variere i liten grad, fordi utførelsen ifølge oppfinnelsen muliggjør et tilnærmet konstant gasstrykk. Tilsvarende bedres treffsikkerheten i merkbar grad., The exit velocity that a projectile 1 according to the invention gets after the form-closing connection 11, 12 has been broken will only vary to a small extent, because the design according to the invention enables an approximately constant gas pressure. Correspondingly, accuracy is noticeably improved.,
