Abstract : The velocities of particles of a viscous solid on the free surface of an ablative body submitted to hypersonic re-entry conditions are analytically determined. The viscosity of the liquid formed during the ablative process is considered to be constant. The problem is treated with the aid of Hankel transforms for a semi-infinite flat body submitted to normal pressure and skin friction on its plane boundary. A viscous liquid layer uniformly spread on a solid sphere is also considered and the solution is given in the form of a Fourier series with the boundary conditions represented approximately.
