The ground boom signatures and drag coefficients for the baseline and optimized NACA0008 airfoil with different suction and injection slot sizes. a the maximum overpressure vs the slot size; b the maximum underpressure vs the slot size; c comparison of the ground boom signature at the suction slot size = 7.2%c; d the drag coefficient vs the slot size; e the lift coefficient vs the slot size; f the lift-drag ratio vs the slot size
