ABSTRACT	Three-dimensional upwind flux-split Navier-Stokes codes are applied to examine hypersonic flow around HOPE01 configurations.Numerical results are compared with experimental data from the National utations were conducted using a Mach number of 12.0 and 15.0.Aerothermodynamic heating distributions were compared in detail with Calspan′s shock tunnel data and fairly good quantitative agreements were obtained.Real gas effects were also analyzed using a chemical non-equilibrium Navier-Stokes code which was developed by combining finite-rate chemical reactions to the current use perfect gas flux-split code.A fully implicit alternative directional implicit(ADI)scheme is employed to avoid the stiffness problem occurring in the time integration process.Typical real gas effects on aerodynamic characteristics are revealed.This work was conducted as joint research of NAL and the National Space Development Agency(NASDA).
