Abstract
A mechanism responsible for a decrease in the turbulent friction of bodies moving in (or streamlined by) a vibrationally-nonequilibrium gas flow is proposed. Heating of the gas in the immediate vicinity of the surface as a result of heterogeneous relaxation may decrease the transverse velocity gradient and reduce the friction resistance coefficient.
