Summary

Surface catalytic efficiencies of glassy coatings were determined from a reaction boundary layer computation and arc-jet data. The catalytic efficiencies of the various coatings examined are discussed in terms of their reaction-rate constants. These constants are a function of the wall temperature (1290°K≤T., ≤2000°K). In addition, the advantage of a thermal protection system for a bent-biconic aeroassisted orbital transfer vehicle (AOTV) with a low surface catalytic efficiency is discussed.
