Computer and Experimental Evaluation of Drag Reduction of Blunt Bodies at Supersonic Speeds by Counterflow Combustion - Concept of a "Flame" Spike

Abstract

This report results from a contract tasking Chalmers University of Technology as follows: The contractor will provide the following (a) A theoretical/computational background to evaluate drag reduction effect for different kinds of "flame" spikes in the range of M=2-6 free stream conditions; (b) Results to determine energy release conditions leading to the stable flow regimes; (c) Experimental information to illustrate drag reduction effect for bodies of particular geometries and specific heat releases; (d) Software that can be used to search for new effective fuel compositions; (e) Render necessary assistance in performing similar computations or experiments, if requested; and (f) Limits of the concept applicability.
