With the continuous increasing size and flexibility of large wind turbine blades,aeroelasticity has been
be coming a significant subject for wind turbine blade design. There have been some examples of
commercially developed wind turbines experiencing aeroelastic instability problems in the last decade,
which spokes for the necessity of aeroelastic modelling of wind turbine blades. This paper presents the
state-of-the-art aeroelastic modelling of wind turbine blades,provides a comprehensive review on the
available models for aero dynamic,structural and cross-sectional analysis,discusses the advantages and
disadvantages of these models,and outlines the current implementations in this field. This paper is
written for both researchers new to this research field by summarising underlying theory whilst presenting a comprehensive review on the latest studies,and experts in this research field by providing a
comprehensive list of relevant references in which the details of modelling approaches can be obtained.
