The paper presents the results of experimental studies on determination of the drag and lift force of a rotating cylinder with a porous surface within the airflow velocity range from 5 to 13 m/s (Re = 40,000-105,000) at a constant rotation of the cylinder around its axis. There are also presented the results of studies of drag and lift force of a single rotating cylinder within the range of the cylinder revolutions number around its axis from 400 to 1,400 rev/min at a constant air flow rate. It is shown that the drag coefficient and the lift force coefficient depend on the Reynolds number and the cylinder revolutions number. The dependence of the coefficients of aerodynamic characteristics on the degree of porosity of the surface of the rotating cylinder is established.
