CHALLENGE - In the past century, low Reynolds number airfoil design for both military and civil applications has continued to capture the interest of practitioners of applied aerodynamics

SOLUTION - A new design methodology for airfoils has been developed, which controls the airfoil profile through 8 parameters. The airfoil aerodynamic characteristics were predicted through the XFOIL code, to optimize airfoil under modeFRONTIER environment. The reliability verification result predicted that the XFOIL code can be used to determine the airfoil performance in the linear segment of the lift coefficient curve.

BENEFITS - The result shows that the XFOIL code can well predict the aerodynamic performance of airfoils in the linear segment of the lift coefficient curve for low Reynolds number, although the maximum lift coefficient tends to be over predicted.
