This paper presents a quantitative investigation of the effect of structural damping ratios of the tower and blade vibration modes of wind turbines on wind-induced fatigue loads at critical blade and tower sections. Fatigue loads are used as a relative measure of fatigue life in wind turbine design applications. By increasing the structural damping ratio of each one of the critical structural modes which highly contribute to the overall vibration response, short-term and lifetime fatigue loads at critical tower and blade sections are calculated considering parked and operating conditions for different mean wind speeds as well as lifetime operational conditions.

Investigation of the effect of bending twisting coupling on the loads in wind turbines with superelement blade definition Gözcü, Mehmet Ozan; Kayran, Altan; Department of Aerospace Engineering (2014) In this thesis study, the effect of off-axis plies in the spar caps of a wind turbine blade on the damage equivalent loads in a wind turbine system is investigated. The off-axis plies in the spar caps are exploited for load alleviation in the whole turbine system since the off-axis plies induced bending-twisting coupling into blades of wind turbine. Damage equivalent load is used to assess the effect of bend twist coupled blade on the fatigue load reduction in the whole wind turbine system. NREL's 5 MW turb...
Evaluation of the Effect of Spar Cap Fiber Angle of Bending-Torsion Coupled Blades on the Aero-Structural Performance of Wind Turbines Şener, Özgün; Gozc, M. Ozan; Kayran, Altan (ASME International, 2018-08-01) This paper presents a comprehensive study of the evaluation of the effect of spar cap fiber orientation angle of composite blades with induced bending–torsion coupling (IBTC) on the aero-structural performance wind turbines. Aero-structural performance of wind turbines with IBTC blades is evaluated with the fatigue load mitigation in the whole wind turbine system, tower clearances, peak stresses in the blades, and power generation of wind turbines. For this purpose, a full E-glass/epoxy reference blade has ...
Comparative study of transient and quasi-steady aeroelastic analysis of composite wind turbine blade in steady wind conditions Sargın, Hakan; Kayran, Altan; Department of Aerospace Engineering (2014) The objective of this study is to conduct a comparative study of the transient and quasi-steady aeroelastic analysis of a composite wind turbine blade in steady wind conditions. Transient analysis of the wind turbine blade is performed by the multi-body dynamic code Samcef Wind Turbine which uses blade element momentum theory for aerodynamic load calculation. For this purpose, a multi-body wind turbine model is generated with rigid components except for the turbine blades. For the purposes of the study, a r...
Genetic algorithm based aerodynamic shape optimization of wind turbine rotor blades using a 2-d panel method with a boundary layer solver Polat, Özge; Tuncer, İsmail Hakkı; Sezer Uzol, Nilay; Department of Aerospace Engineering (2011) This thesis presents an aerodynamic shape optimization methodology for rotor blades of horizontal axis wind turbines. Genetic Algorithm and Blade Element Momentum Theory are implemented in order to find maximum power production at a specific wind speed, rotor speed and rotor diameter. The potential flow solver, XFOIL, provides viscous aerodynamic data of the airfoils. Optimization variables are selected as the sectional chord length, the sectional twist and the blade profiles at root, mid and tip regions of...
Determination of the bending twisting coupling potential of composite materials via digital image correlation and its implementation in wind turbine blades Şener, Özgün; Kayran, Altan; Department of Aerospace Engineering (2017) In this thesis study, the main objective is to investigate the effect of bending-twisting coupling in composite wind turbine blades on the load alleviation, power generation and structural performance of the wind turbine system. For this purpose, experimental and numerical study is initially conducted to determine the bend-twist coupling potentials of composite materials. Bending-twisting behavior of composite materials are determined through a comparative study via the Digital Image Correlation (DIC) syste...
