Original abstract
The technical diagnostics of 125 mm tank cannon 2A46 smooth barrel and ramming devices are discussed respectively. Focuses on barrel diagnostics and suggests new procedures based on reconstructed BG20 Gun Barrel Bore Gauge System, measuring internal diameter of the barrel bore. The new system measures throughout the whole barrel bore the inner diameter not only at the beginning of barrel bore as it was usually measured before. Different nature of barrel wear was revealed between barrels firing sub-calibre and high explosive projectiles. A method for ramming device diagnostics is presented. An accurate method was proposed, determining projectile extraction force from barrel, as one of the main ramming device parameters for weapons that are used in all areas of armed forces. Results are based on experimental methods assessing the extraction forces from barrel after projectile loading. These tests were performed as a series of tests with consequent technical diagnostics according to the new Czech Defence Standards (derived from NATO standards). The results are presented as the new methodologies for diagnostics of 125 mm barrel 2A46 and ramming devices of tank T-72 for use by technical logistic units in the Czech Republic Armed Forces.
Czech abstract
Článek pojednává o technické diagnostice vývrtu hlavně 125 mm kanónu 2A46 a nabíjecího zařízení. V první části je položen důraz na diagnostiku vývrtu hlavně a je navržena původní metodika založená na rekonstruovaném britském diagnostickém systému BG20. Nová metodika nahrazuje původní ve smyslu rozšíření hodnocení opotřebení hlavně po celé délce vývrtu. V článku je analyzován různý charakter opotřebení vývrtu hlavně způsobený střelbou podkaliberními a tříštivo-trhavými střelami. Druhá část článku řeší problematiku technické diagnostiky nabíjecího zařízení tanku. Za hlavní parameter nabíjecího zařízení je navržena hodnota výtahové síly, obdobně jak je tomu i u jiných vyspělých armád. Prezentované výsledky jsou podloženy experimenty měření výtahových sil nutných pro extrakci nabitých střel. Všechny experimenty byly provedeny v souladu s novými českými obrannými standardami odvozenými od standardů NATO. Článek jako celek prezentuje nově vytvořené metodiky pro diagnostiku hlavně 125 mm kanónu 2A46 a nabíjecího zařízení tanku T-72 určené pro logistické útvary AČR.
