Design optimization of a multi-stage axial compressor using through flow and a database of optimal airflows

Journal of the Global Power and Propulsion Society, 2018
The basic tool set to design multi-stage axial compressors consists of fast codes for throughflow and blade-to-blade analysis. Detailed blade row design is conducted with 3D CFD, mainly to control the end wall flow.

Optimization of High‑Speed WIG Airfoil with Consideration of Non‑ground Effect by a Two‑Step Deep Learning Inverse Design Method

Transactions of Nanjing University of Aeronautics and Astronautics
Under complex flight conditions， such as obstacle avoidance and extreme sea state， wing-in-ground （WIG） effect aircraft need to ascend to higher altitudes， resulting in the disappearance of the ground effect.

Airfoil Design Using Genetic Algorithms

Genetic algorithms (GAs) are a search method used in finding true or approximate solutions to optimization and search problems. They have been applied in different fields like computer science, engineering, and economics. Here, we apply GA to the problem of designing a symmetric airfoil with high lift coefficient. Each population member, or chromosome,
