Roskam gives the following equation to calculate the stall speed for a given wing loading and maximum lift coefficient.
V_s = sqrt(2 * W/S/(C_L_max * rho))/1.688
If I'm not mistaken, a vortex generator does not affect the wing's lift coefficient. Rather, they just keeps the airflow energized so it stays attached at higher angles of attack than without vortex generators. So quantitatively, how would vortex generators affect the above equation to reduce the stall speed?
