High-fidelity aerodynamic shape optimization using efficient orthogonal modal design variables with a constrained global optimizer (2017, methodology): “Case 1 had been used previously to consider the performance of the domain element method using design variables that have been designed using user intuition [11].”
Domain-Element Method for Aerodynamic Shape Optimization Applied to a Modern Transport Wing (2009, methodology): “The parameterization technique developed has several key advantages: 1) The number of design variables required to allow free-form design can be very low, when compared with other methods [15].”
Aircraft control surface deflection using RBF‐based mesh deformation (2011, background): “RBF-based mesh deformation has gained popularity in recent years in the context of FSI and optimization (see [9–11, 17, 26, 27] and [17, 18], respectively).”
Metric-Based Mathematical Derivation of Efficient Airfoil Design Variables (2015, methodology): “Conversely, the more general control point-based methods have the advantage of being able to use a hierarchical set of design variables, the number of which can be set by the user depending on the problem, and vary from minor control point position perturbations up to entire groups of control points”
