Abstract
We present the results of CFD calculations of the hypervelocity flow of nitrogen about a slightly blunted cone at an angle of incidence. We use Pullin's Equilibrium Flux Method, and include the effect of finite rate dissociation and recombination chemical reactions vis the Lighthill-Freeman model of the ideal dissociating gas. Test results with the chemical reactions frozen are compared with the perfect gas calculations of Marconi for the same flow geometry and Mach number. The results for chemical reacting flow show substantial interaction between the gas dynamics and the chemistry on the leeward cone surface
