The article presents the results of the experimental investigation aimed at studying the effect of a turbulent wake on the flow around a model of an unmanned aerial vehicle. The studies were carried out in a subsonic wind tunnel at low Reynolds numbers. Hot-wire and pneumometric measurements were the main methods for obtaining numerical data. The thread was used as the source of disturbances. The measurements were carried out in different modes. The thread was stretched in the working part of the tunnel at some distance from the model. The graphs of the distribution of static pressure and average velocity over the model surface were obtained. The results obtained showed a significant influence of the turbulent wake on the flow around the model.
