Researching Influence of Vortex Generators on Aircraft Aerodynamic Characteristics

This paper deals with researching the influence of vortex generators on the aircraft’s aerodynamic characteristics. The principle of operation of vortex generators is explained. The full characteristics of blowing models of profiles are given. The process of designing blowing models is described including technological features. Samples of models of vortex generators printed on a 3-D printer are shown. The algorithm for creating the shape of the volumetric vortex generator ensures its formalization. The process of developing the shape of the vortex generators is explained. The profile models were studied in the wind tunnel. Different angles of attack during these experiments were used. The interconnection between the intensity of the vortex generator and the angle of attack is explained. The results of researching the influence of vortex generators on the aerodynamic characteristics of the aircraft are represented. The graphical dependences of the influence of the turbulator and vortex generator on the aerodynamic characteristics of aircraft are given. The obtained experimental results can be useful for the aircraft of the wide class.
