Paper Abstract

The results of experimental studies of fluctuations of the parameters of a laser beam propagating through a supersonic submerged jet (SJ) at selected distances from the nozzle are presented. The measurements were performed at different distances perpendicular to the beam axis. The results of the analysis of the intensity fluctuations and the directions of the phase front (performed using a coordinate-sensitive photodetector) are considered. The results of studies of the propagation of a laser beam over a wing model, which is installed in a closed wind tunnel T-313, are analyzed.
