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).

A CFD-informed quasi-steady model of flapping-wing aerodynamics [PDF]

open access: yes, 2015
Aerodynamic performance and agility during flapping flight are determined by the combination of wing shape and kinematics. The degree of morphological and kinematic optimization is unknown and depends upon a large parameter space.
