Abstract： In this paper, analyzing the experiment data of multiple scanning probes in the arc wind-driven hypersonic plasma flows with the chaos dynamics method, we have obtained the power spectrum, the frequency wavenumber spectral density, the correlation dimension and Kolmogorov entropy of the flows, respectively. The distribution of correlation dimension and Kolmogorov entropy of the blunt cone wakes along the axis and the radius of the flows are presented successfully in the flows. The distributions clearly show the structure of turbulence and lamination in blunt cone wakes. Using the method of minimum Kolmogorov entropy, we observed the structure of the bow shock at far wake region in the blunt cone wakes.
