| Abstract | Abstract : Computational fluid dynamics solutions have been performed to evaluate flowfield separation effects resulting from the firing of a divert thruster on a biconic endoatmospheric interceptor. Comparisons are made with cold jet wind tunnel data in order to validate the prediction model which is then applied to hot jet flight conditions at a higher Mach number and momentum flux ratio. Scaling of the wind tunnel results to flight based on momentum flux ratio implies the existence of a large separated region onto the interceptor fore cone. Simulation results for the hot jet, however, showed no separation onto the fore cone. The reasons for these differences are primarily attributed to the higher freestream Mach number and lower specific heat ratio in the hot jet case. Other issues concerning the scaling of cold jet wind tunnel results to flight are also discussed. |
