Stationary shape of bodies ablating in hypersonic flow under the action of radiation heating
Abstract
The stationary shape of axisymmetrical blunt bodies subjected to ablation as a result of radiative aerodynamic heating in an equilibrium hypersonic air flow is analyzed on the basis of a method proposed previously for calculating the radiant flux distribution over the surface of bodies. It is found that the stationary shape depends slightly on the governing parameters of the problem and is close to hyperboloids of revolution with asymptote angles in interval 90-100 deg. It is shown that the regular shape of certain meteoric bodies can be fully explained by quasistationary ablation processes associated with radiation heating during motion through the dense layers of the atmosphere.
