Abstract

Purpose - To outline a transonic wing design problem by applying real coded genetic algorithm (GA) and dynamic mesh technique to reduce the optimization time and cost. Design/methodology/approach - Dynamic mesh technique was used in the design of a transonic wing by matching it with heuristic algorithms. Findings - It is observed that the drag coefficient can be reduced by 25 percent. While this has been done, the lift coefficient is tried to be close to the design value determined at the beginning as a design constraint. Originality/value - It is the first time that the dynamic mesh technique is used for regenerating the mesh structures of the new population members in the GA. © Emerald Group Publishing Limited.
