Abstract
On the basis of certain assumptions and simplified processing, hydrodynamic model describing the process of the influent was gotten. The numerical analysis of the process of water injection into both frontal equilibrator and back one was done. And the variation of the influent volume with time was gotten. On the basis of the mathematical model, the paper simulated the trajectories of the underwater launch vehicle for different velocities of water injection before separation and for different initial velocities. The simulation results were in good agreement with the experiment results. The reliability of the trajectories simulation results was proved.
