A vortex generator is a small component that has shaped as a fin and located on upper the surface of the wing or stabilizer to do modification the airflow around the wing surface that affects the boundary layer. In this research, analysis of the aerodynamic characteristic has been done by using computational fluid dynamics (CFD). The purpose of this analysis is to find out the difference in the airflow between NACA 2412 with an additional gothic vortex generator and NACA 2412 without an additional vortex generator, and also to find out the airflow characteristic on NACA 2412 with varying angle of attack. The Research method used is analysis simulation on test object airfoil NACA 2412 with an additional gothic vortex generator with straight configuration with the angle of attack variation 0°, 2°, 4°, 6°, 8°, 10°, 12°, 15°, 16°, 17°,19°, 20°, 23°, and 25°. Space between installed vortex generator is 60 mm with the size of vortex generator length is 25 mm, height 10 mm, and installed on x/c = 10% and 15% direct to chord line from the leading edge. The result of the research shows that the additional vortex generator on NACA 2412 can delay airflow separation. In 15% additional position direct to the chord line from the leading edge has better distribution and the highest lift coefficient, so in this research, the 15% additional position direct to the chord line from the leading edge is the most effective to use.
