Uticaj početne mase baruta na model dvofaznog strujanja u cevi automatske puške / Influence of starting powder mass on a two-phase flow model in the automatic riffle tube

Abstract

Jednofaktorskim planom eksperimenta u radu je izvršena analiza svih polaznih parametara koji se javljaju u procesu dvofaznog strujanja u cevi automatske puške. Prikazan je potpuni plan faktorskog eksperimenta 24 početne mase baruta sa odabranim parametrima i analiziran njihov uticaj na izlazne karakteristike. Kompletna analiza (disperziona i regresiona) izvršena je za maksimalni pritisak barutnih gasova i početnu brzinu projektila, kao veoma bitne izlazne karakteristike svakog oružja. / The one-factor plan of the performed experiment gave us a chance to analyze all starting parameters that appear in the process of two-phase flow in the tube of the automatic riffle. Here we present a comprehensive plan of the factory experiment starting mass of powder with chosen parameters and analyze their effects on the outgoing characteristics. A complete analysis (depressive and regressive) is performed for the maximum pressure of powder gases and the starting speed of the projectile, as very important outgoing characteristics of any weapon.
