Abstract

Sporlysprojektil hvis kappe for forankring av hylsekanten har en kryraperille (2) som går rundt, idet det mellom krymperillen (2) og hekken (3) er anordnet en i tetningsrille (4).Spore light projectile whose jacket for anchoring the sleeve edge has a creeping groove (2) which rotates, one between the shrink groove (2) and the rear (3) being arranged in a sealing groove (4).

Den vanntetthet hos patroner som kreves for militærammuni-sjon oppnås i alminnelighet ved at man plasserer bitumenLakk i1 hylsemunningen. The watertightness of cartridges required for military ammunition is generally achieved by placing bitumen lacquer in the sleeve mouth.

På. grunn av at sporlysprojektil er laget med en lengre sylin-i derdel og en relativt kortere avrunning av hekken, skrapes J normalt bitumenlakken vekk ved innsetning av ammunisjon L j den lakkerte hylsemunning og derved går dens tettende virk-i ning tapt. On. due to the fact that the tracer projectile is made with a longer cylinder part and a relatively shorter rounding of the rear, the bitumen coating is normally scraped away when ammunition L is inserted into the lacquered casing mouth and thereby its sealing effect is lost.

I Denne alminnelig kjente effekt tar man hensyn til ved de tekniske leveringsbetingelser ved at det tillatelige feijL--i i t'a.ll kan være større enn ved den tilhørende mykkjerneammuni-i sjon. I This commonly known effect is taken into account in the technical delivery conditions in that the permissible error in t'a.ll can be greater than in the case of the associated soft nuclear ammunition.

i j i Tross disse tillatte høyere feiltallene er det stadig vanske-i lig i masseproduksjonen å oppnå en tilsvarende kvalitet, i j i Despite these permitted higher error rates, it is still difficult in mass production to achieve a corresponding quality,

i og det ble derfor utviklet fremgangsmåter for å forbedre i vanntettheten ved ytterligere påføring av tetningsmidler litterat patronene var ferdige. i and methods were therefore developed to improve the watertightness by further application of sealants after the cartridges were finished.

i i i Disse tetningsmidler har imidlertid negative innvirkninger på hylsematerialet ved at oksydasjonsforløp på overflaten påvirker den optiske kvalitet, hvorunder eventuelt alvorlige konsekvenser ikke er utelukket gjennom korrosjon. i i i These sealants, however, have negative effects on the sleeve material in that oxidation processes on the surface affect the optical quality, where possible serious consequences through corrosion are not excluded.

Oppfinnelsen vedrører en spesiell konstruksjonsform av pto-sjektilet som gjør det mulig uten anvendelse av ytterligeIr<e>i The invention relates to a special form of construction of the pto-sectile which makes it possible without the use of additional Ir<e>i

tetningsmidler å oppnå en bedre vanntetthet bare med deni vanlige innvendige lakkering av hylsen med bitumenlakk, slik at den blir likeverdig med mykkjerneammunisjonen. sealants to achieve a better watertightness only with the usual internal coating of the sleeve with bitumen varnish, so that it becomes equivalent to the soft core ammunition.

Denne tetningseffekt oppnås ifølge oppfinnelsen ved at I patronen mellom krymperillen og hekken er forsynt med en*teitningsrille. I denne rillen får man en oppsamling av den tetningslakk som fortsatt er tilstede ved innføring av patronen i den lakkerte hylsen og den danner derved en tetnings-ring som går rundt projektilet. Ved smøringen av rillen for-andres heller ikke den utvendige ballistiske formen til projektilet, slik at utførelsesformen av projektilet ifølge oppfinnelsen i så måte er likeverdig med ethvert standard sporlysprojektil. This sealing effect is achieved according to the invention by providing a sealing groove in the cartridge between the shrinking groove and the rear. In this groove, you get a collection of the sealing varnish that is still present when the cartridge is inserted into the varnished sleeve, and it thereby forms a sealing ring that goes around the projectile. The lubrication of the groove also does not change the external ballistic shape of the projectile, so that the embodiment of the projectile according to the invention is in this respect equivalent to any standard tracer projectile.
