Aerodynamic Design Optimization Using Genetic Algorithm (RESEARCH NOTE)

An efficient formulation for the robust shape optimization of aerodynamic objects is introduced in this paper. The formulation has three essential features. First, an Euler solver based on a second-order Godunov scheme is used for the flow calculations. Second, a genetic algorithm with binary number encoding is implemented for the optimization procedure. The third ingredient of the procedure is...

Aerodynamic Shape Optimization of Wing and Wing-Body Configurations Using Control Theory

This paper describes the implementation of optimization techniques based on control theory for wing and wing-body design. In previous studies [18, 19,221 i t wasshown that control theory could be used to devise an effective optimization procedure for airfoils and wings in which the shape and the surrounding body-fitted mesh are both generated analytically, and the control is the mapping functio...

Dynamic aerodynamic-structural coupling numerical simulation on the flexible wing of a cicada based on ansys

Most biological flyers undergo orderly deformation in flight, and the deformations of wings lead to complex fluid-structure interactions. In this paper, an aerodynamic-structural coupling method of flapping wing is developed based on ANSYS to simulate the flapping of flexible wing. Firstly, a three-dimensional model of the cicada’s wing is established. Then, numerical simulation method of unste...

Aerodynamic Optimization of Transonic Wing Design Based on Evolutionary Algorithm

Evolutionary Algorithm (EA) is applied to a practical three-dimensional shape optimization for aerodynamic design of an aircraft wing. Aerodynamic performances of the design candidates are evaluated by using the three-dimensional compressive Navier-Stokes equations. A structural constraint is introduced to avoid an apparent solution of zero thickness wing for low drag in high speeds. To overcom...

Aerodynamic Wing Optimization via Evolutionary Algorithms Based on Structured Coding

Abstract Evolutionary Algorithms (EAs) based on structured coding have been proposed for aerodynamic optimization of wing design. Fractional factorial design is used to investigate interactions of the design variables to determine the appropriate coding structure for EAs in advance. The present EAs is applied to wing design problems where the wing shape is modeled using the parameter set for th...
