Aerohydrodynamic surface, array of vortex generators, and method of mounting array of vortex generators

An aerohydrodynamic surface, including an array of vortex generators and a main part, wherein

• the main part comprises two sides mating with each other to form a leading and a trailing edge and is also formed longitudinally by at least one streamlined profile at least in the front part,
• the array of vortex generators includes elevations with crescent-shaped working edges located near the leading edge so as to be fully or partially located in the flow stagnation zone at a given angle of attack and to exit from the flow stagnation zone when the angle of attack changes relative to the given one, and the frontal projections of the working edges are fully or partially located at an angle of 60 to 80° to the frontal projection of the leading edge and intersect the frontal projection of the leading edge so as to generate attached vortex structures and to increase the boundary layer energy on one of the sides of the aerohydrodynamic surface,
• characterized in that
• the elevations and the working edges are configured to generate counter-rotating vortex structures, wherein
• the ratio of the distance between the midpoints of the frontal projections to the height of the frontal projections is from 0.5 to 1.5 and the tangents to the midpoints of the frontal projections are located at an angle of 20 to 60° to each other for two working edges configured to generate counter-rotating vortex structures.
