A Fortran IV computer code is described which computes thermochemical ablation rates of pyrolytic graphite surfaces, as a function of surface temperature and pressure, assuming all heterogeneous reactions at the surface are kinetically controlled. The calculation of the chemical state at the surface utilizes a film coefficient model which accounts for the unequal diffusion of species. All homogeneous reactions between gas-phase species adjacent to the surface are assumed to be in equilibrium. The specific surface reactions which are taken to be kinetically controlled include the reactions of condensed-phase carbon with water vapor, carbon dioxide, and hydrogen. Several options are available for computation of the boundary-layer edge state required in the diffusion model, including isentropic expansion or compression, and normal or oblique shock wave calculation procedures.
