Abstract
The objective of this study is to introduce aerofoils distribution as a design variable in wind turbine blade optimisation process. Aerodynamic optimisation is performed using a genetic algorithm (GA). An aerofoil-pairing database is developed to define a heuristic used in the GA rather than using a random selection in order to improve the GA performance. The aerodynamic characteristics of the transitional section between two aerofoils are obtained using a mathematical model. The model is constructed based on the results of numerical analysis of blended aerofoils using non-linear data regression techniques. Using stall-regulated wind turbine AWT-27 as a case study, the enhanced capability of the design code in optimisation of the topology of the original blade is shown.
