This paper presents the solution to a non-linear non-stationary heat transfer problem in a double-layer heat shield coating on a metal hemispherical shell with an axisymmetric distribution of the heat flow density over the outer coating surface. The coating's outer layer material has thermal conductivity anisotropy characterized by a ratio of the thermal conductivity coefficients along and across the layer. The resulting solution has been used to quantitatively assess the thermal behavior of such a coating on a ballistic capsule when it enters the dense layers of the Earth's atmosphere with a velocity close to a parabolic one, with a single preliminary dipping into the atmosphere and entry into a near-earth orbit before the final stage of descent.
