| Abstract: | A theoretical method for optimizing multi-element airfoils in separated flow is presented to determine the optimum location and deflection angle of flap or slat relative to the main component corresponding to the optimum CLmax. We take the maximum lift coefficient as the objective function. This approach is used to calculate the maximum lifts of NLR 7301 airfoil and GA(w)-l airfoil. The optimum computations are carried out for GA (w)-l airfoil. The results of the calculations are in good agreement with the wind-tunnel testing results. |
