Aerodynamic Optimization of Morphing Airfoil by PCA and Optimization-Guided Data Augmentation

Aerospace
An aircraft that has been carefully optimized for a single flight condition will tend to perform poorly at other flight conditions. For aircraft such as long-haul airliners, this is not necessarily a problem, since the cruise condition so heavily ...
