Abstract

Anhui University of Technology, Anhui Maanshang 24300,China (Received April 01 2019, accepted June 07 2019) In \u00a0view \u00a0of \u00a0the \u00a0numerical \u00a0calculation \u00a0of \u00a0zero-dimensional \u00a0interior \u00a0ballistics \u00a0is \u00a0not \u00a0efficient \u00a0for catapult interior ballistic engineers and it is difficult to simulate the flow field in the two-dimensional interior ballistic \u00a0numerical \u00a0simulation, \u00a0combining \u00a0with \u00a0computer \u00a0simulation \u00a0technology, \u00a0we \u00a0build \u00a0a \u00a0gas-ejection interior ballistic simulation platform according to the idea of system structure. In this platform, the numerical simulation of gas-ejection interior trajectory is carried out from zero-dimensional and two-dimensional interior trajectory \u00a0mathematical \u00a0model. \u00a0The \u00a0simulation \u00a0of \u00a0interior \u00a0ballistic \u00a0flow \u00a0field \u00a0is \u00a0accomplished \u00a0by \u00a0fluid mechanics \u00a0software, \u00a0and \u00a0output \u00a0the \u00a0images \u00a0of \u00a0the \u00a0interior \u00a0trajectory \u00a0characteristic \u00a0parameter \u00a0curve \u00a0and temperature, velocity and pressure field. To help engineers to study the impact of structure parameters, material parameters \u00a0and environmental coefficients on missile \u00a0ejection. Through the use of military unit testing, the platform has been validated.
