“…Common parameterization for aerodynamic shapes includes splines (e.g., B-spline and Bézier curves) [47][48][49], free-form deformation (FFD) [25,26], class-shape transformations (CST) [50,51], PARSEC [52,53], and Bézier-PARSEC [54].…”

“…Both the upper and lower surfaces are represented as separate NURBS curves that have been optimized to fit the original airfoil as per the method of Lépine et al [31]. The NURBS curves, control polygon, and original airfoil are presented in Fig.…”

“…not too close to the leading and the trailing edge (since it clearly leads to an unrealistic wing section). The angle of incidence can also be taken as a fourth design parameter, and will be studied in the next cases, since it influences the aerodynamic performance of the airfoils (Lépine et al, 2001). In the present case, the angle of attack is fixed because its influence dominates that of the other parameters (e, m and p).…”
