Abstract
This relates to the field of aerohydrodynamics and can be used on wings and control surfaces of aircraft, controlled spoilers of sports cars, all-movable masts and sails of sailing yachts and sailboards, as well as on blades and vanes of various bladed machines. An aerohydrodynamic surface includes an array of vortex generators and a main part. The main part comprises two sides mating with each other to form a leading and a trailing edges. The array of vortex generators includes elevations with crescent-shaped working edges located near the leading edge. The elevations and the working edges are configured to generate counter-rotating vortex structures. An array of vortex generators and a method of mounting the same onto the aerohydrodynamic surface are also described. The invention makes it possible to improve the properties of the aerohydrodynamic surfaces at high angles of attack.
