The main purpose of this work was the experimental investigation of the effect of a saw-tooth trailing edge of a wing main element on the aerodynamics characteristics of a single flap. The saw-tooth trailing edge consists of triangles on the trailing edge of the main element of the wing in order to promote mixing between the higher-pressure flow from the lower surface with the flow on the upper surface.
