In this study, the topic studied was the characteristics of airflow passing through the gothic-type generator vortex by the smoke generator method. The purpose of this study was to visually observe the characteristics of the airflow on the upper surface passing through the NACA 43018 airfoil with varying angle of attack positions. The vortex profile of the generator x/c = 20% of the leading edge. Variations in this study are the angle of attack (α) and the placement of the generator vortex on the airfoil. The freestream speed used is a speed of 5 m/s, and at an angle of attack (α) of 0°, 3°, 6°, 9°, 12°, and 15°. From this study, it was found that the ratio of separation points between airfoils without VG compared to airfoils with VG and D = 10 mm at angles of attack (α) = 0°, 3°, 6°, 9°, 12°, and 15° had significant differences in separation points. Airfoil with VG and D = 20 mm at an angle of attack (α) = 0°, 3°, 6°, 9°, 12°, and 15° can delay separation better than D = 10 mm.
