Abstract: In the framework of the parabolic viscous shock layer theory (PVSL) the hypersonic thermochemical nonequilibrium air flow over blunt body with catalytic surface moving along prescribed aerodynamic reentry trajectory at incidence and slipping angles is investigated. The interaction between vibrational relaxation and chemical proceses on the basis of a preferential vibration-dissociation-exchange reactions coupling model (CVDEV) is taken into account. The high accuracy implicit numerical algorithm is used, which does not imply symmetric planes existence in flow and does not need a preliminary solution to the Stefan-Maxwell relations with respect to the diffusion fluxes. The influence of the body shape, of the attack and slipping angles, of the heterogeneous chemical reactions model, of the freestream parameters and of the vibrational nonequilibrium on the heat flux and of the equilibrium surface temperature is analyzed.
