In this paper, the effect of RV (Reentry Vehicle) control vane on stability of a launch vehicle in the atmospheric outgoing phase will be analyzed. Despite of necessity for stability or control purposes in atmospheric re-entry phase, the RV vane has adverse effects on the stability of the whole launch vehicle in the phase of atmospheric outgoing. For analyzing this, a pilot launch vehicle is selected, the geometry is modeled in GAMBIT, flight data is extracted and using FLUENT, the launch vehicle conditions is simulated and the stability results is extracted for analyzing that shows the adverse effects of RV control vane on whole launch vehicle stability. Finally, some suggestions are offered.
