Effects of Mass Additions on Viscous Flow Parameters

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.
