水压式垂直发射装置内弹道建模与分析

A mathematical interior ballistic model was established to study the launch process of hydraulic submersible vertical missile launchers. A method based on the one-dimensional flow hypothesis and the momentum equation of gap flow between two parallel plates was used to solve transient annular gap flow. A quasi-one-dimensional interior ballistic model of vertical launchers was established by combining the dynamics and kinematics of projectile bodies. The resulting model was in good agreement with computational fluid dynamics simulations. This proposed model addresses issues in transient annular gap flows with large pressure differences between two ends, which are difficult for existing models to handle.
