Abstract

The method for determining the surface catalytic recombination coefficients of Thermal Protection Materials (TPMs) in high enthalpy dissociated flows is established on 1 MW high frequency plasma wind tunnel according to the research development in diagnostics of high enthalpy chemical non-equilibrium flow and surface parameter determination of TPMs. This paper presents the catalytic recombination coefficient of SiO₂, with surface temperature being 1 563-2 003 K, enthalpy being 13.9-21.9 MJ/kg, and stagnation point pressure being 2.7, 5 and 10 kPa. The test results agree well with foreign literatures, indicating reliability of the method for determination of catalytic recombination coefficient. The method proposed can provide support for precise prediction of aerodynamic heat environment and more accurate design of TPMs.
