Aerodynamic Performance Estimation of Camber Morphing Airfoils for Small Unmanned Aerial Vehicle [PDF]
Journal of Aerospace Technology and Management, 2020 This paper proposes a methodology to harvest the benefits of camber morphing airfoils for small unmanned aerial vehicle (SUAV) applications. Camber morphing using discrete elements was used to morph the base airfoil, which was split into two, three, and ...

Efficient Aerodynamic Shape Optimization in MDO Context [PDF]
PAMM, 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]
10th 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).
