Computational aeroheating predictions for X-34

Radiative equilibrium surface temperatures, heating rates, streamlines, sur face pressures, and flowfield features as predicted by the LAURA are presen ted for the X-34 Technology Demonstrator. Results for two trajectory points corresponding to entry peak heating and two control-surface deflections ar e discussed in detail, outlining the effects of the boundary-layer state an d various flow features on the heat transfer rates and corresponding wall t emperatures. These data are also discussed in the context of thermal protec tion system design issues, indicating that only minor changes needed to be made to the existing layout. The work presented is part of a larger effort to define the X-34 aerothermal environment, including the application of en gineering codes and wind-tunnel studies.
