Abstract: In this paper the analysis calculation of jet internal flow field of the plenum in the missile vertical launching system is presented.By FLIC method with conservation from scheme and the exlicit artificial viscosity, the normal shock is captured in supersonic jet impingement flow field.The calculation results indicate that the maximun static pressure in the flow field locats at the axisymmetric center line of the jet aad decreases continuously in the radial direction, which is in accordance well with the experimental data by Bouslog, S.A.et al.
