Abstract

Oppfinnelsen vedrører ammunisjon for missilvåpen og skytevåpen. Den kaviterende kjerne ifølge oppfinnelsen omfatter en hodedel sammenføyd med en sekantspissflate langs en kaviterende kant; en sentral del; og en akterdel med en glideflate, hvor kjernens kaliber er angitt ved maksimumsdiameteren til den sirkel som omskriver kjernens tverrsnitt. Det særegne ved den kaviterende kjerne er at den konturlinje som omhyller tverrsnittene fra den kaviterende kant til kjernekaliberen i planet for kjernens aksiale lengdesnitt, er begrenset gjennom følgende avhengighet: Dx = d x [1 + (Lx/d) x (2 x sin f/p)1/N]N; hvor - Dx er den gjeldende diameter, angitt i mm, på kjerneomhyllingskonturen R; - d er diameteren, angitt i mm, på den kaviterende kant; - Lx er den gjeldende avstand, angitt i mm, fra den kaviterende kant til kjernekaliberen; - f = 60°...270° er toppvinkelen for tangentene til sekantspissflaten ved punktene for dens sammenføyning, med den kaviterende kant målt fra hodedelens side; og - N = (2p/f)0,4...(2p/f)0,2 er kjernevolumsfaktoren, hvor kjernekaliberen er lik den gjeldende diameter på kjerneomhyllingskonturen Dx. Oppfinnelsen gjør det således mulig å øke den effektive av stand for å treffe mål under vann ved skyting fra luft til vann, og/eller under undervannsskyting ved bruk av armbrøster, harpunvåpen, artilleri, håndvåpen og sports- og jaktvåpen.
