Abstract

The invention is on the airfoil (1) in the case of low speed operations of aircraft, micro and unmanned aerial vehicles and turbine blade structures used in the aviation and energy sectors; it contains its leading edge (10), which is the part where the fluid first meets the front, and its trailing edge (20) left by the fluid entering from its leading edge (10). It is the airfoil (1) that increases the aerodynamic performance and efficiency with the controlling the flow on the suction or the upper (30) and the pressure or the lower (40) surfaces, thus increasing. The airfoil (1) contains suction (30) the upper silicone-based flexible plate (70) and the lower silicone-based flexible plate (71) inserted into the upper gap (60) and the lower gap (61), located between the leading edge (10) and the trailing edge (20), which prevents the formation of separation bubbles on the suction (30) and the pressure (40) surfaces of the airfoil (1).
