چکیده

Search for safety and high efficiency is the driving force in the aerospace industry. This paper reports on application of a relatively new and very promising evolutionary algorithm SOMA with the intent to answer the question on optimal wing geometry. We describe aerodynamic model of the wing, the evolutionary optimisation process and results we obtained. In this contribution present a modern, high performance global optimisation algorithm applied on real engineering application resulting into a set of evolutionary-designed wings which we developed in cooperation with a leading civil aircraft design bureau and manufacturer. Key–Words: Evolutionary algorithms, Aerodynamics, Optimisation

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...

Transonic 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...

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...

Topology Optimisation: Increasing the Speed and Reliability of Design

In this paper, topology optimisation is applied to the design of the rear fuselage of an unmanned aerial vehicle (UAV). A comparison is drawn between the performance of a design created through evolutionary structural optimisation (ESO) and a baseline design modelled on a manually designed and successfully flow fuselage geometry, for different wing shapes. The loading for each wing shape is det...
