The paper experimentally investigate the influence of Reynolds number on the drag coefficient of various models, while blowing in the wind tunnel. The article describes in detail the procedure of the experiment, as well as an algorithm for computing analyzed parameters on the basis of the data during the experiment measurements. Shows the values of drag coefficient obtained in a series of experiments with different Reynolds numbers and configurations of scale models. The results obtained are in good agreement with the linear dependence this coefficient on the Reynolds number. On the basis of the data obtained on the approximation to the zone of self-similaritywith increasing flow velocity. Failure to achieve this zone caused by performance characteristics of the wind tunnel, used in the experiment, namely the inability to compensate for the reduced-size model of with flow rate or the properties of gas used for blowing.
