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.

Computational Aerodynamic Design Optimization
Volume 6: Turbo Expo 2003, Parts A and B, 2003Quasi-1D Euler equations have a considerable part of research to allow the prediction of the internal and external flows of the aerodynamic applications. Numerical solving of these equations by a so-called computational fluid dynamics (CFD) finds a very close agreement of the flow solver regarding to the experimental tests. Using CFD in the aerodynamic

Perching aerodynamics and trajectory optimization
SPIE Proceedings, 2007Advances in smart materials, actuators, and control architecture have enabled new flight capabilities for aircraft. Perching is one such capability, described as a vertical landing maneuver using in-flight shape reconfiguration in lieu of high thrust generation.

UNCERTAINTY BASED ROBUST OPTIMIZATION IN AERODYNAMICS
Modern Physics Letters B, 2009The Taguchi robust design concept is combined with the multi-objective deterministic optimization method to overcome single point design problems in Aerodynamics. Starting from a statistical definition of stability, the method finds, Nash equilibrium solutions for performance and its stability simultaneously.

Cooling and Aerodynamics Simultaneous Optimization
SAE Technical Paper Series, 1991<div class="htmlview paragraph">Beginning from the mid-70's a clear trend emerged in car aerodynamic design and styling which dictated the lowering of the hood profile and a corresponding reduction of grill openings, while the nose surface remained dedicated to the bumper impact area and car number plate. On the other hand the increasing power of

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].
