Title    Numerical Simulation on Interior Ballistic Process of Bulk Liquid Traveling Charge
Abstract
Muzzle initial velocity is an important indicator to measure the performance of artillery, how to effectively increase the muzzle initial velocity is one of the keys of weapon launch. Traveling charge is a new technique to increase the muzzle initial velocity, in this thesis, The research of interior ballistic for traveling charge of 30mm gunpowder was carried out. The results show that traveling charge technique can effectively increase the initial velocity under the condition of staying the same gun pressure.

Directed on the structure characteristic of traveling charge, and analyzed the interior ballistic process. Two combustion ways, bulk-loaded combusted by layers and spray atomized combustion, were used to the traveling charge powder. Established the zero dimension model respectively for the interior ballistic process of traveling charge. Used fourth-order runge-kutta to salve and written numerical calculated programs by MATLAB, the results were resemble experimental results preferably. On this basis, respectively discussed the effect of different  parameters on interior ballistic performance, such as ignition delay, mass of traveling propellant, traveling propellant burning rate and so on. the results can inform the study of traveling charge technique.
