The effect of the dispersion of graphite microparticles on the attenuation of radiation in a hypersonic compressed layer
Abstract
Experimental and theoretical studies are presented on the ablation of graphite materials, which show promise as heat-resistant spacecraft materials. An analysis is presented of the attenuation of radiation from graphite-ablation products in the form of microparticle pairs for an axisymmetric body. A system of conservation equations for a hypersonic compressed layer is solved along with an integrodifferential equation of radiation transfer, with allowance for radiation scattering. It is shown that, in the region of vapor transport, the fractional composition of the microparticles has a significant effect on the attenuation of the radiative heat flux to the ablating surface.
