Effect of Shape Parameterization on Aerodynamic Shape Optimization
45th AIAA Aerospace Sciences Meeting and Exhibit, 2007This paper studies the effect of shape parameterization on automatic aerodynamic shape optimization. Four shape parameterization techniques are studied: mesh points, Hicks-Henne bump functions, B-spline curves and the PARSEC method. The objective is to compare them based on accuracy and impact on the computational cost.

Robust aerodynamic shape optimization—From a circle to an airfoil
Aerospace Science and Technology, 2019Aerodynamic design optimization currently lacks robustness with respect to the starting design and requires trial and error in the flow solver and optimization algorithm settings to get a converged optimal design. We address need issue by developing ways

Aerodynamic shape optimization of turbomachinery cascades
13th Computational Fluid Dynamics Conference, 1997During the last years, steadily increasing interest in computer based methods for aerodynamic shape optimization can be observed. The approaches that emerged up to now can be divided mainly into two groups methods based on genetic algorithms and numerical optimization methods.

Aerodynamic Shape Optimization Methods
1997Although fast and accurate in creating aerodynamic shapes compatible with the specified surface pressure distribution, the inverse shape design methods create configurations that are not optimal even at the design operating conditions [163], [164].
