Studies On Influence Of Plasma Ignition To The Interior Ballistic Performance Of The Gun With Modular Charges

In the modern war, modular charge techniques has become the development trend of larger caliber artillery guns as a new concept launch technology. As the plasma ignition has the following advantages:ignition delay time is short, repeatable ignition, easy to eliminate the powder charge regarding the temperature sensitivity, can increase the rate of gas generation and so on.. In the field artillery firing it has been gradually applied. Take the plasma ignition technology for the module artillery charge system, you can give full play to their strengths, to interior ballistic performance optimized. This paper mainly research the interior ballistic performance of the plasma ignition to the artillery guns with module charges. The main contents of this thesis including:(1) Through analyzed and simplified the interior ballistic process of the artillery guns with module charges ignited by plasma, Established one-dimensional two-phase flow mathematical model on the Interior Ballistic process of before and after the module breakdown respectively;(2) Use reasonable numerical method, using Fortran language computer program on the Interior Ballistic Model is simulated;(3) By a detailed analysis on the results of numerical simulation, to study the influence of plasma center ignition to the interior ballistic performance of the gun with six and four congruent modular charges, and analyzed the plasma input energy of the plasma center, tube length, nozzle pitch and other factors on Interior Ballistic Performance.
