Efficient Aerodynamic Shape Optimization in MDO Context [PDF]
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]
