Transonic Wing Design by Inverse Optimization Using Moga
An inverse optimization method coupled with a multiobjective Genetic Algorithm has been applied to design a transonic wing for mid-size regional aircraft. Optimization of target pressure distributions was formulated to give minimum induced drag as well as minimum profile drag. The straight isobar pattern of pressure contours was specified on the upper surface of the wing. To design a realistic ...
متن کاملOptimum Transonic Wing Design Using Control Theory
1. Introduction While aerodynamic prediction methods based CFD are now well established , and quite accurate and robust, the ultimate need in the design process is to find the optimum shape which maximizes the aerodynamic performance. One way to approach this objective is to view it as a control problem, in which the wing is treated as a device which controls the flow to produce lift with minim...
متن کاملAerodynamic 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...
متن کاملTransonic Wing Shape Optimization Based on Evolutionary Algorithms
A practical three-dimensional shape optimization for aerodynamic design of a transonic wing has been performed using Evolutionary Algorithms (EAs). Because EAs coupled with aerodynamic function evaluations require enormous computational time, Numerical Wind Tunnel (NWT) located at National Aerospace Laboratory in Japan has been utilized based on the simple master-slave concept. Parallel process...
