Airplanes can fly because of the slightly curved shape of the plane’s wings called the airfoil. Airfoil is still used by aircraft today but continues to be designed to get maximum results. The research method used is a simulation analysis method on the NACA 0012 test object with ANSYS-CFD software which is given a variation in the shape of a rectangle vortex generator with a length of 15 mm, a width of 10 mm, and a distance between vortex generators of 10 cm. The angles of attack reviewed are 0°, 2°, 4°, 6°, 8°, 10°, 12°, 14°, 15°, 16°, 18°, and 20°. The result of this simulation is that the presence of a rectangular vortex generator on airfoil NACA 0012 can affect both performance and aerodynamic characteristics. The vortex generator on the airfoil can delay the occurrence of separation and can delay the occurrence of stall on the NACA 0012 airfoil, where the ordinary NACA 0012 airfoil stalls at α = 14° with the addition of the vortex generator has not stalled at this point. With this, the NACA 0012 airfoil which is given a vortex generator can affect the results of CD. Overall, the most optimal variation is the NACA 0012 airfoil which is given a vortex generator with x/c = 15% where the value of CD is greatest at an angle of attack α = 18°.
