N2 - Chemically non-equilibrium neutral gas mixture flows of N(2)/N and O(2)/O with electronic excitation are studied. The one-temperature model of transport properties taking into account electronic states of both molecules and atoms is developed. The generalized Chapman-Enskog method is applied to derive the closed set of governing equations and to evaluate the transport terms. The transport coefficients of thermal conductivity, diffusion and thermal diffusion, shear and bulk viscosity, as well as the Prandtl number are calculated in the temperature range 500-50000 K for various mixture compositions. Contribution of the electronic degrees of freedom to the transport properties is found to be important, especially for atomic species.
