Chemical-kinetic parameters of hyperbolic Earth entry

Chemical-kinetic parameters governing the flow in the shock layer over a heat shield of a blunt body entering Earth's atmosphere from a hyperbolic orbit are derived. By the use of the assumption that the heat shield is made of carbon phenolic and by allowing for an arbitrary rate of pyrolysis-gas injection, chemical reactions occurring in the shock layer are postulated, and the collision integrals governing the transport properties, the rate coefficients of the reactions, and the parameters needed for the bifurcation model and for the finite-rate kinetic wall boundary conditions are determined using the best available techniques
