CORE 7.62 mm rifle bullet

摘要

The invention relates to the bullets of small arms ammunition. The development of new ammunition there is a need to know the effectiveness of their actions on the target at different distances as well as to assess the breakdown of the bullets looking at the design stage. The purpose of the utility model - the breakdown of the increase in nominal 7.62 mm rifle bullet B-32 and the possibility of assessing the impact of the breakdown of geometric dimensions on the action. Rifle bullet have a structure consisting of a core and shell jacket. The main element affecting a bullet core, so increasing the breakdown action is achieved by changing the shape of the core. Experimental studies using the theory of planning, let go to the solution of the interpolation problem. Where factors - the geometric dimensions and the response function - the depth of penetration into the barrier. Numerical analysis allowed us to determine in solving the interpolation problem dependent influence of geometrical dimensions on the penetration depth and conduct optimization resulting equations - to the optimal shape of the head. We obtain a new form of core with its parameters (dimensions).
