Abstract
Hypersonic flow past a body entering the earth's atmosphere on a glide path is studied. The computational results for the heat fluxes and th e surface temperature obtained using different approximations for the VV' relaxation time are compared with one another. The source terms in the vibrational-relaxation equations are estimated and it is shown th at the back effect of chemical reactions on the vibrational-energy bal ance must be taken into account.
