Abstract:

The objective of the effort is to re-evaluate the influential mechanisms of interaction between re-entry body heat shield ablation and aerodynamic parameters, based upon data obtained under the preceding STREET-G contract, other ground test data, with analytic results, and with applicable flight test data. The specific objectives of this research are to improve 1 the empirical correlations which account for mass injection effects on the viscous layer thicknesses, 2 the basic turbulent relations for predicting the viscous properties, and 3 the validity of the Crocco integral for turbulent flows with mass injection. The influence of the improved correlations on the vehicle drag for some typical flight vehicles is also ascertained.
