Abstract
Oppfinnelsen angår en fremgangsmåte ved avfyring av artilleriprosjektiler, så som forskjellige typer granater (1, 26) fra riflete løp (5a, 5b) for å hindre graden av slitasje av løpet hvorfra prosjektilene blir avfyrt, i å ha en negativ virkning på munningshastigheten av prosjektilene. Oppfinnelsen omfatter også et antall artilleriprosjektiler eller granater (1, 26) konstruert i samsvar med fremgangsmåten og en fremgangsmåte for å fremstille disse. Oppfinnelsen omfatter et antall forskjellige varianter for å løse det angitte problem, hvor hovedprinsippet ved alle disse variantene er å kunne justere båndposisjonene av granatene etter graden av løpslitasje, slik at det oppnås en perfekt drivgasstetning hele tiden mellom båndet (9, 11-14, 19-21, 23 og 33) og opprinnelsesstedet for riflingen i løpet uansett graden av løpslitasje.The invention relates to a method of firing artillery projectiles, such as various types of grenades (1, 26) from rifled barrels (5a, 5b) to prevent the degree of wear of the barrel from which the projectiles are fired, in having a negative effect on the mouth velocity of the projectiles. . The invention also encompasses a number of artillery projectiles or grenades (1, 26) constructed in accordance with the method and a method for making them. The invention encompasses a number of different variants to solve the stated problem, the principal principle of all these variants being to adjust the belt positions of the grenades according to the degree of running wear, so that a perfect propellant gas seal is obtained all the time between the belt (9, 11-14, 19 -21, 23, and 33) and the point of origin of the rifle regardless of the degree of running wear.
