Abstract

Computational analysis of High Speed Flight Demonstrator (HSFD) Phase II Vehicle and HOPE-X are presented. HSFD Phase n is the flight experiment to reduce uncertainties in the HOPE-X transonic aerodynamics. HSFD vehicle is 25% scale model of HOPE-X. The phase II flight experiment will be scheduled at the Swedish Space Corporation's Esrange site in Sweden in 2002 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 and HOPE-X models and total aerodynamic performance including base regions has been investigated along the planned flight conditions. 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 by NAL and EHI transonic wind tunnels and Boeing polysonic wind tunnel. In order to correlate the wind tunnel data to flight conditions, sting interference effects are studied for 2.7% and fiill scale HOPE-X model with Reynolds number effects. Finally, OMS nozzle effects on aerodynamics are also analyzed.
