Efficient Aerodynamic Shape Optimization in MDO Context [PDF]

open access: yesPAMM, 2005
AbstractThe aerospace industry is increasingly relying on advanced numerical flow simulation tools in the early aircraft design phase. Today's flow solvers, which are based on the solution of the compressible Euler and Navier‐Stokes equations, are able to predict aerodynamic behaviour of aircraft components under different flow conditions quite well [1]

Efficient Aerodynamic Shape Optimization [PDF]

open access: yes10th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2004
Since the present author first became involved in computational fluid dynamics, around 1970, the landscape has changed dramatically. At that time, panel methods had just come into use, and the world’s fastest super computer, the Control data 6600, had only 131000 words of memory (about 1 megabyte).

GCN-based 3D aerodynamic optimization design based on discrete adjoint method

open access: yesKongqi donglixue xuebao
Gradient-based optimization algorithms, particularly the discrete adjoint method, are widely used in aerodynamic shape optimization due to their independence from design variable dimensionality.
