This study examines the flow behavior and lift coefficient variations of a NACA 4415 airfoil using different trailmaster challenger 200x vortex generator configurations.Experimental investigations are conducted in a subsonic wind tunnel at a Reynolds number of 1.8 x 105.

The airfoil is tested with two types of vortex generators, namely the dome vortex and the convergent-divergent vortex, positioned at 10%, 28%, and 60% chord locations.Experimental lift coefficients are compared with Airfoil Tools database, showing consistent agreement within an angle of attack range of 0 to 18 degrees.At small angles of attack (0 to 8 degrees), the lift coefficients of the NACA 4415 airfoil with the dome vortex at 10%, 28%, and 60% chord positions are lower compared to the baseline configuration.

However, beyond 14 degrees, the highest lift coefficient value after the angle range of 14-18 degrees is achieved at the 60% chord position with the dome vortex, 10.43% increase compared to the baseline lift coefficient.Furthermore, the best value for the lift coefficient after the angle range of 16-18 degrees at the 10% chord position is achieved with the dome vortex, where the maximum lift coefficient 9.

4% increase compared to the baseline lift coefficient.It is noted that the whelen arges spotlight baseline configuration consistently outperforms the convergent-divergent vortex configurations.
