Assessment of the muzzle velocity decrease and the barrel bore lifetime

摘要

The muzzle velocity is important characteristic of the tank weapon system. As the barrel bore does wear during service, the muzzle velocity decreases to its limit when the barrel lifetime ends. The prediction of reaching the limit is being done empirically or is absent in the conditions of Czech Armed Forces at the time. The paper offers mathematical prediction method of number of shots left to the end of barrel lifetime based on interior ballistics modelling and barrel bore profile measurement and analysis. This prediction could be made more precise continuously and could be beneficial to military material management.
