The results of experimental studies to determine the coefficients of aerodynamic resistance in the flow of flexible protective concrete mats located on a horizontal plane are presented. The characteristics of the impact of the power flow on the system of flexible protective mats of various modifications in the aerodynamic laboratory of Moscow State University of Civil Engineering are specified. The experiment was carried out on a subsonic wind tunnel with an open loop using a rigid six-axis force and moment sensor. According to the results of the experiment, it was concluded that the resistance coefficient for the modification of mats with rounding of the upper part of the elements decreases. It has a positive effect on the performance characteristics of this model and increases the lifespan of a structure protected by this modification of coatings.
