Abstract

The concentration of steady-state perturbations of the flux field on the symmetry axis in axisymmetrical hypersonic aerodynamic tubes [1] is analyzed. A description of the increment in the amplitude of the perturbations is presented on the basis of the linear theory. The “critical∝ frequency bounding the frequency spectrum of the focused perturbations is estimated.
