A new technique was studied aimed at controlling energy-intensive coherent vortex structures (ECVS) that define the processes of mass- and heat transfer in vortex chambers. This is important because the swirled flows are employed in a wide class of machines and devices. The basic principle of the method implies rational organization of targeted controlling actions on ECVS using the systems of ordered vortex cords that run down the end edges of a miniature thin wing. The wing is mounted in a flow-through tract of the inlet nozzle of the vortex chamber at different angles of attack. Using the wing with a small elongation significantly extends the range of continuous angles of attack. Combined with strict requirements to the streamlined surfaces (especially near the leading edge of the wing), it reduces the aerodynamic drag. We obtained data on aerodynamic blowing for three types of profiles. Relatively thin profiles were selected to ensure the permanence of lifting coefficient over a rather wide range of the Reynolds numbers. Controlling actions at the maximum value of Reynolds number at the inlet to a nozzle Re max =95,000 and at the maximum continuous angles of attack of the wing MB253515 alsmost do not affect the chamber's aerodynamic drag. However, there is a growth of the relative intensity of velocity pulsation at the outlet of the chamber from 10 % to 2 2% for the circular component, and from 47 % to 63 % for the axial component. We propose theoretical and experimental substantiation of the examined technique based on the principle of mutual susceptibility of vortex structures.
