Certain structural measures make it possible to obtain a uniform flow in a wind tunnel test section with a low degree of turbulence. One of these measures is grids in the prechamber of the wind tunnel which equalize the fields of average speed and reduce the intensity of turbulent fluctuations. This article gives the results of an investigation on the effect of the specific resistance of a grid and a number of grids in sequence on reduction of the turbulent fluctuations in speed.
