Abstract

This study aims to develop a simple and efficient design optimization methodology for the low Reynolds number airfoils. XFOIL is used as an aerodynamic solver while modeFRONTIER workflow is employed for the design optimization purpose. The airfoil SG6043 is used as the reference airfoil for optimization due to its common applications when long-endurance characteristics are desired. A simple design optimization methodology with the integration of XFOIL in the modeFRONTIER workflow environment is proposed in this study. The proposed “software integration methodology” demonstrated up to 10% improvement in the optimization parameter which makes it more efficient by reducing the optimization time and steps without unnecessary user intervention which are the limitations conventionally associated with the optimization process. The optimization results are further compared with the results of the numerical simulations. The use of the transition-sensitive turbulence model allowed the evaluation of the behavior of the laminar separation bubble for different angles of attack, observing that it shifts towards the leading edge and has its length reduced as the angle of attack increases. The newly generated airfoil exhibits improved aerodynamic characteristics as compared to the base airfoil. The optimized airfoil can be used in the applications of UAVs as well as in general aviation. Further validation of the airfoil using wind tunnel testing is recommended and planned.
