Title Interior ballistics numerical simulation of cylinder launching
Abstract With the development of the modern war, many more operation functions have been derived from the cylinder launching technology to satisfy different operational requirements. In this paper, the interior ballistic process of the cylinder launching system undergoes a mathematical modeling and simulation calculation to reveal its working principle. The first attention is paid to the structural characteristics of the launching system and the launching process. Then the simplification based on the classical theory of interior ballistics leads to a mathematical modeling. The ballistic calculation program during the launching process is composed in the VB language environment and the numerical calculation is realized according to the classical Range-Kutta formula. In this way the ballistic process simulation of the cylinder launching system is achieved. With the simulation of launching process under given conditions and a systematic analysis of the calculation data, a regular pattern comes to light about how the loading conditions influence the ballistic properties of the cylinder launching system. The model proves reasonable and feasible after calculation. In the end, another analysis is conducted of the influence of loading parameters and structural parameters on the ballistic performance, aimed at providing some parameter reference to the structural and loading design of the launching system.
