Computational Aeroheating Predictions for X-34

Abstract
Radiative equilibrium surface temperatures, heating rates, streamlines, surface pressures, and flowfield features as predicted by the LAURA are presented for the X-34 Technology Demonstrator. Results for two trajectory points corresponding to entry peak heating and two control-surface deflections are discussed in detail, outlining the effects of the boundary-layer state and various flow features on the heat transfer rates and corresponding wall temperatures. These data are also discussed in the context of thermal protection 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 engineering codes and wind-tunnel studies.
