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,

A novel approach to inverse design of wind turbine airfoils using tandem neural networks

Wind Energy
The performance of a wind turbine and its efficiency majorly depends on wind‐to‐rotor efficiency. The aerodynamic design of the wind turbine blades using high‐fidelity tools such as adjoint‐computational fluid dynamics (CFD) is accurate but ...
