![]() ![]() The distance of the vortex generator to the leading edge is x/c = 10% and 15%, the swept angle is 15°, and the angle of attack varies. The type of vortex generator used is a triangular vortex generator with a length of 25 mm, and a height of 10 mm with a straight installation. This study used NACA 23018 specimens which were given variations of the vortex generator and swept back wing. In this research, aerodynamic testing is carried out, using numerical simulation with Ansys software. With the slightly curved side of the airfoil, there is a point of separation in the airflow passing through the airfoil. Airfoil is a geometric shape that when placed in a fluid flow will produce a lift greater than the drag force (drag).
