Abstract

A search-based multi-point aerofoil design algorithm is presented which optimises a profile for a prescribed CL-α distribution and Reynolds number, Re. A real-coded genetic algorithm is used in conjunction with XFOIL and a geometrically constrained shape parameterisation method to produce smooth, manufacturable aerofoils given the required aerodynamic performance. The validated tool is used to produce a family of aerofoils to define a model rotor blade for a wind turbine with a similar axial induction factor along its length in a small scale laboratory environment to a full scale reference. It is hypothesised that given the similar axial induction and similar non-dimensional geometry, the model rotor will have a similar unsteady aerodynamic response to the full scale.
