Domain-Element Method for Aerodynamic Shape Optimization Applied to a Modern Transport Wing (2009, methodology): “Awide variety of shape control andmorphingmethods have been developed [1–11], but these often do not allow sufficiently free-form design, can produce infeasible shapes, and do not allow the possibility of manual manipulation of the geometry [12,13].”
A study of airfoil parameterization, modeling, and optimization based on the computational fluid dynamics method (2016, methodology): “Kulfan (2007) presented a novel two-step airfoil fitting technique, namely CST, which is defined as 1 2 ( ) ( ) ( ),NNC S (1) where φ stands for x/c, and c is the chord length.”
CFD-based optimization of hovering rotors using radial basis functions for shape parameterization and mesh deformation (2013, methodology): “1995), polynomial or spline (Braibant and Fleury 1984), CAD and recently CST (Kulfan 2007) methods.”
A Geometric Comparison of Aerofoil Shape Parameterisation Methods (2016, methodology): “Class Function/ Shape Function Transformations (CST) The CST method was developed by Kulfan[7, 42] primarily as a method of defining a wide range of aerofoils with relatively few design variables; however, the method can also be extended to other shapes such as square-like and”
CFD‐based optimization of aerofoils using radial basis functions for domain element parameterization and mesh deformation (2008, unknown): “The class function/shape function transformation (CST) [20, 21] method is a recent addition to parameterization methods.”
