Abstract
Results of calculation of the mean intensity of an optical beam crossing a shock wave arising at the supersonic flowing the turret at the beginning of a path in a homogeneous medium are present. It is shown that the spatial inhomogeneity of the refractive index of air in the area occupied by a shock wave can cause strong anisotropic distortions of a beam intersecting a shock wave. The distortions leads to focusing and fragmentation of a beam at relatively small distances from the turret and its quick degradation during further propagation.
