“…But Kyle also put too much emphasis on the cost of the blade manufacture, and ignored the possibility of balancing the cost through the improved power and fatigue property. With the maturity of the design technology of torsion coupling blade, Alireza and other researchers have developed a comprehensive procedure combining aerodynamics and the coupling of the blade structure to accurately predict the angle of attack and bending moment of the adaptive blade during the process of design as well as the output power (Maheri et al, 2006;Maheri et al, 2007), which has reduced the heavy finite element calculation task in the process of optimization design thus saving the time and efforts in calculation. After that, they soon started to develop a set of design tools (Maheri & Isikveren, 2009a, 2009b of adaptive blade.…”

“…A simple matrix operation transforms the elemental stiffness matrix from natural to global system of coordinates. It has been shown that it is an accurate and reliable element for analysis of thin and moderately thick anisotropic shell structures, even when using coarse meshes [3][4][5][6]. Therefore, TRIC has been selected for the FE solver part of the package as it is of the desired robustness, accuracy and efficiency and fulfils all the above requirements.…”

A high performance finite element analysis software tool has been developed for high fidelity deformation analysis of aeroelastic tailored wings and blades made of anisotropic composite materials. The package comprises an in-line semiautomatic adaptive mesh generator and a finite element solver. An aerodynamic solver can be plugged into the package to perform a coupled aero-structure analysis. The finite element solver employs a natural-mode triangular shell element, yielding accurate results with high convergence rate in deformation analysis of thin and moderately thick composite shell structures. In mesh generation, the aerodynamic and structural characteristics of the aeroelastic structure directly influence the domain discretization procedure. It has been shown that a mesh generated based on this algorithm has significant effect on improving the convergence rate of results.

“…All of these factors make linking commercial codes inefficient and cumbersome and developing a code especially designed for this purpose a necessity [10]. WTAB is a coupled aero-structure code developed for simulating wind turbines with BT smart blades [11], which is a combination of an aerodynamic code, an adaptive mesh generator and a finite element solver, all developed especially for this purpose. Many unique features of this code, i.e.…”

AbstractThe induced deformation, due to the presence of elastic coupling in the structure of passive smart blades, is the key parameter that affects the wind turbine performance. Therefore, when predicting the aerodynamic performance of these turbines, a structural analyser is also required to bring the effect of the induced deformation into account. This diverts the numerical simulation of wind turbines utilising passive smart blades from the simulation of wind turbines with traditional blades. In performance prediction, additional complexity arises when the blades are bend-twist-coupled. In this case an iterative coupled-aero-structure analysis must be carried out. Further difficulties in simulation of these turbines are posed by the fact that the current analytical models for analysis of structures made of anisotropic composite materials are not accurate enough. Different strategies have been proposed and followed by investigators to embark upon the above highlighted problems. The present paper describes, evaluates and compares these approaches.
