This paper presents a computational parametric study showing how heat release affects aerodynamic characteristics, drag and heating rate, of a hypersonic flow over an axisymmetric blunt body. A chemical non-equilibrium viscous flow is assumed together with seven chemical species and finite-rate chemical reactions. Results show that heat release in the upstream of the body can reduce not only the aerodynamic drag but also the aerodynamic heating rate on the body. Three parameters which control heat release are introduced and their effects on the flow structure, especially on the drag and the heating rate, are presented. It is shown that the drag is reduced to 23% of the baseline value (the drag of the flow without heat release) and the aerodynamic heating rate to 76%.
