A large number of flow simulations about HOPE-X (H-2 Orbiting Plane Experimental) has been carried out to support its aerodynamic design. In order to investigate the aerodynamic characteristics in detail, preliminary computations of transonic flows about HOPE-X with -20-degree steered elevons were executed. The CFD (Computational Fluid Dynamics) code used here is based on Reynolds averaged Navier-Stokes equations discretely divided using FVM (Finite Volume Method) method with TVD (Total Variation Diminishing) upwind scheme. The computational grid used here is multi block structured one consisting of 42 blocks. Total number of the grid-points is about 3.7 millions.
