The Continuous Adjoint Approach in Aerodynamic Shape Optimization
2006Detailed numerical shape optimization will play a strategic role for future aircraft design. It offers the possibility of designing or improving aircraft components with respect to a pre-specified figure of merit subject to geometrical and physical constraints. However, the extremely high computational expense of straightforward methodologies currently

Aerodynamic Shape Optimization of a Stator
Volume 12C: Turbomachinery — Design Methods and CFD Modeling for Turbomachinery; Ducts, Noise, and Component InteractionsAbstract In this paper, a numerical study conducted on a compressor stator is presented. The results are compared with existing literature and experimental data. For this purpose, a grid refinement study for the baseline geometry at the design condition with an unstructured mesh family is performed.

Massively parallel aerodynamic shape optimization
Computing Systems in Engineering, 1992Abstract We consider the problem of finding the shape of an airfoil which produces a pressure distribution closest to a desired one. The flow is modeled by the nonlinear potential equations of compressible flow. The problem is formulated as an optimization problem constrained by a discrete approximation to a nonlinear boundary value problem.

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].

Variable-Fidelity Aerodynamic Shape Optimization
2011Aerodynamic shape optimization (ASO) plays an important role in the design of aircraft, turbomachinery and other fluid machinery. Simulation-driven ASO involves the coupling of computational fluid dynamics (CFD) solvers with numerical optimization methods.

Aerodynamic Shape Optimization of Heat Exchangers
2023The development of efficient methods to reject waste heat has been instrumental throughout aircraft design history. In current airliners heat exchangers cool the cabin air, avionics, and engine oil. As the aviation industry transitions toward electric or hydrogen-powered propulsion, heat exchangers will become more important.

Aerodynamic Shape Optimization by Space Mapping
2013This chapter describes an efficient aerodynamic design optimization methodology for wings in transonic flow. The approach replaces a computationally expensive high-fidelity computational fluid dynamic model (CFD) in an iterative optimization process with a corrected polynomial approximation model constructed by a cheap low-fidelity CFD model.
