The stationary rate of propagation of a turbulent reaction front is conside
red taking into account a finite rate of perturbation propagation in a turb
ulent medium. The parameter of the problem is the ratio between the charact
eristic reaction time and the relaxation time of turbulent pulsations. If t
his ratio equals one, the rate of reaction front propagation is a maximum a
nd equals the rate of turbulent pulsations. If this ratio is much smaller t
han one, the solution transforms into the Kolmogorov-Petrovskii-Piskunov so
lution to the problem of biological population growth.
