We consider an isotropic homogeneous cosmological model with five interactingelements: first, the dynamic aether presented by a unit timelike vector field,second, the pseudoscalar field describing an axionic component of the darkmatter, third, the cosmic dark energy, described by a rheologic fluid, fourth,the non-axionic dark matter coupled to the dark energy, fifth, the gravityfield. We show that the early evolution of the Universe described by this modelcan include two specific epochs: the first one can be characterized as asuper-inflation, the second epoch is associated with an oscillatory regime. Thedynamic aether carries out a regulatory mission; the rheologic dark fluidprovides the specific features of the spacetime evolution. The oscillations ofthe scale factor and of the Hubble function are shown to switch on theparametric (Floquet - type) mechanism of the axion number growth.
