Abstract

U ovom završnom radu opisana je problematika vezana za otklon cijevi topa tenka 2A46 uslijed
balističkih i meteoroloških uvjeta. U analizi su obuhvaćene različite vrste streljiva te je opisan način kako
pojedini parametri balističkih i meteoroloških uvjeta utječu na otklon cijevi topa u horizontalnoj i
vertikalnoj ravnini. Ponajprije, u kratkim je crtama opisan povijesni razvoj tenkovskih topova
općenito, zatim su nabrojani dijelovi cijevi i pojašnjena njihova uloga, posebice termoizolacijske obloge. U svrhu shvaćanja otklona cijevi, prije detaljne analize, objašnjeno je
ponašanje visokolegiranih (visoko čvrstih) čelika u uvjetima povišene temperature. Analizom
otklona dobiva se uvid u ponašanje cijevi tijekom opaljenja te parametre koji značajno utječu na
njen otklon od cilja, kao i generalni smjer kretanja cijevi nakon ispaljenog projektila. Na kraju
opisani su načini trošenja cijevi te dani prijedlozi za smanjenje istog.

Abstract (english)

This final paper describes in detail the deflection of the 2A46 tank gun barrel due to ballistic and
meteorological conditions. The analysis includes different types of ammunition and a certain
way and how certain ballistic and meteorological conditions affect the deflection of the tank gun
barrel in horizontal and vertical planes. Firstly, the historical development of tank guns is
described briefly, then the parts of the barrel will be listed and their role explained, especially its
thermal shroud. In order to understand the concept of barrel deflection, prior to more detailed
analysis, the behavior of high-strength steels under elevated temperature conditions is explained.
By analyzing the deflection, the reader is acquainted with the behavior of the barrel during the
firing process and parameters which significantly affect the barrel’s deflection of the target, as
well as the general direction of barrel movement after projectile is fired (under operating
conditions). Lastly, barrel wear mechanisms are described and techniques to decrease it given.
