Machine learning in aerodynamic shape optimization
Progress in Aerospace Sciences, 2022 Machine learning (ML) has been increasingly used to aid aerodynamic shape optimization (ASO), thanks to the availability of aerodynamic data and continued developments in deep learning. We review the applications of ML in ASO to date and provide a perspective on the state-of-the-art and future directions. We first introduce conventional ASO and current

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.

Comparison of optimization algorithms for aerodynamic shape design
AIAA Journal, 1996Three different optimization algorithms are applied to airfoil design. A simplified test problem is considered here so that the distribution of the objective function can be plotted. The visualization of the objective function will reveal which optimization strategy is preferable. The results of three optimization algorithms will be easy to compare and

Aerodynamic Shape Optimal Design in Automotive Headlamp
2009 International Joint Conference on Computational Sciences and Optimization, 2009The optimization of aerodynamic shape of headlamp is helpful to enhance automotive aerodynamics and appearance. As aerodynamic shape parameters of headlamp are complex and their values are ambiguous, the paper optimizes aerodynamic shape parameters of headlamp by use of orthogonal experimental design based on numerical simulation.

Improving the efficiency of aerodynamic shape optimization
AIAA Journal, 1994The paper demonstrates two new improvements for the design procedure that increase the computational efficiency of an aerodynamic shape optimization procedure. The numerical procedure is based on discrete sensitivity analysis to compute the design gradient information as opposed to the traditional finite difference approach.
