The special features of hypersonic gas flow over blunt 
bodies with excitation of additional degrees of freedom (vibrational 
or electronic) are studied using computer modeling based on numerical 
integration of the nonstationary system of complete Navier-Stokes 
equations. Calculations over a wide range of determining parameters 
indicated the existence of regions of weak and strong flow instabilities 
in gases with small effective adiabatic exponents for finite disturbances 
of the parameters in the incident flow.
