PROJECT QUALITY MANAGEMENT OF COMPLEX INTERIOR BALLISTIC SYSTEMS
Project Management College, Belgrade, petarj@fon.rs Ljubiša Tančić Military Academy, Belgrade, ljtancic@gmail.com
Abstract: The interior ballistics problem of firing process in the small arms is considered. A mathematical model of a so-called two-phase flow, which is described by gas - dynamic partial differential equations system, is used, without deducing them. Partial differential equations system has been solved numerical by finite difference method. The equations system convergence and stability conditions are taken by occasion of the scheme choice. Calculations by mathematics model are realized on the PC computer. The research experimental method of propellant gas pressure with results of measuring is given. The results of measuring are analyzed and they compared with the results of mathematical model and useful conclusions to line of directions for future work on this problem are given. Key words: project quality management, interior ballistics, firing process, model of two-phase flow, small arms barrel
