Results of detached-eddy simulations of the Reentry-F vehicle are presented and compared to the experimental data. Comparisons between the detached-eddy turbulence model and a traditional Reynolds-averaged Navier-Stokes model show a substantial improvement in the predicted base heating rates. A grid-resolution study is performed to examine the sensitivity of the detached-eddy formulation to the grid spacing. Initial results at a zero angle of attack indicate a discrepancy with the experiment that is accounted for by the inclusion of a small experimentally measured angle of attack. Moreover, it is observed that the simulations are very sensitive to the vehicle orientation. Upon accounting for this sensitivity, the resulting predicted base pressure and heating are shown to be in very good agreement with the flight data, typically within the stated experimental uncertainty.
