摘要
In this study the effect of catalytic surface properties on heat exchange near the bottom surface of a space vehicle entering the Martian atmosphere was studied. It was shown that the catalytic properties of the frontal and bottom surfaces may significantly influence (up to several times) the levels of heat fluxes. It was found also that the physical adsorption of oxygen atoms leads to an increase of heat fluxes on the surface regions with a temperature lower than 600 K.
