Modern and larger horizontal-axis wind turbines with power capacity reaching 15 MW and rotors of more than 235-meter diameter are under continuous development for the merit of minimizing the unit cost of energy production ($/Kw.hrs). In this context, the European Wind Energy Association has set a target of installed capacity of 150 GW by 2030, whic...

An analytical model for the free vibration of non-uniform, anisotropic, thin-walled wind turbine blade is presented. The blade is constructed from laminated fibrous composite materials with variable thickness and stiffness. The study focuses on the blade spar that represents the main supporting structure within a wind turbine blade. Two specific la...

The design of thin-walled composite blades is optimized in order to provide high dynamic performance. The optimal design is originated with respect to maximum natural frequency criterion. The optimization model employs the concept of spanwise material grading along the blade axis. Spanwise material grading is achieved by changing the distribution o...
