Computational analysis of High Speed Flight Demonstrator (HSFD) Phase 2 Vehicle are presented. HSFD Phase 2 is the flight experiment to reduce uncertainties in the HOPE-X transonic aerodynamics. HSFD vehicle is 25 percent scale model of HOPE-X. The phase 2 flight experiment will be scheduled at the Swedish Space Corporation's Esrange site in Sweden in 2003 and conducted in collaboration with Centre National d'Etudes Spatiales (CNES) of France. In this paper, multi-block Navier-Stokes simulations have been performed for the HSFD model and total aerodynamic performance including base regions has been investigated. Especially, study of the base flow effects is focused on for the accurate prediction of total aerodynamic characteristics. Computational results are compared with the experimental data of NAL transonic wind tunnel at M(sub infinity) = 0.8, 1.05 and 1.2.
