Abstract
Results of the analysis of the mean intensity, intensity fluctuations, and regular and random wandering of optical beams propagating through the high-density area, which is formed due to subsonic airflow about a turret, in a turbulent atmosphere, are described. It is shown that the presence of perturbations around the turret caused by aircraft subsonic movements has a little impact on beam parameter. Quantitative data, which illustrate changes in the beam parameters along paths of different geometry versus turbulent conditions of light propagation, are presented and discussed.
