Airfoil - an overview | ScienceDirect Topics Airfoil is a cross-section of a wing or blade; thus, it is a two-dimensional shape A typical airfoil and its main terminology are shown in Fig 3 1 When an airfoil is located in a fluid flow, as shown in the figure, its first point that hits the wind is called the leading edge (assuming that wind blows from left to right) Similarly, the last point of the airfoil on which the wind leaves the
Airfoils optimization based on deep reinforcement learning to improve . . . In this paper, we propose an optimization framework for rotor airfoils based on DRL technology First, a surrogate model for predicting the aerodynamic coefficient hysteresis loops of the airfoils is built by a deep neural network (DNN) to reduce the cost of flow field computations
Low-Reynolds-number airfoil design optimization using deep-learning . . . To address the issue, we propose to define a compact airfoil design space by extracting modes shapes from a specific class of airfoils rather than the UIUC airfoils These airfoils are customized based on arbitrarily specified airfoil design constraints by using the deep-learning-based optimal sampling method [24]
