© Published under licence by IOP Publishing Ltd.This study focuses on the static and fatigue strength analysis of the existing 5-m RUZGEM composite wind turbine blade with and without defect in the form of debonding. Puck progressive damage analysis is used to investigate the effect of defect introduced to the spar/pressure side interface on the ultimate strength under extreme flap-wise (min) by single-loading point application. In addition, fatigue life according to the Germanischer Lyod (GL) guidelines is determined. For the original blade, collapse is observed after 85% loading, whereas due to defect, failure region changes and the blade collapses after 69% loading. Blade is found to exhibit sufficient resistance against fatigue. However, the inclusion of defect decreases the fatigue life of the blade significantly.

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...
Performance prediction of darrieus type vertical axis wind turbines using numerical simulations Gömeç, Fazıl Selçuk; Sert, Cüneyt; Department of Mechanical Engineering (2014) Flow over Darrieus type straight-bladed vertical axis wind turbines (VAWT) with NACA 0021 blade profile is simulated using ANSYS Fluent software. SST k- turbulence model is used for the two-dimensional, unsteady simulations. Wind speed is taken as 7 m/s and part of the problem domain including the rotating blades is modeled using the sliding mesh technique. Effects of boundary layer mesh parameters, time step and convergence tolerance on the solution accuracy are investigated with carefully designed runs. ...
Structural Performance and Power Production of Wind Turbine Systems with Bend-Twist Coupled Blades in Underrated Wind Conditions Şener, Özgün; Kayran, Altan (2018-01-12) The implementation of bend-twist coupling effect on wind turbine blades on the structural performance and power production of wind turbine system exposed to underrated wind conditions are studied. The structural performance of wind turbine systems are evaluated by the decrease in damage equivalent loads in the whole wind turbine system and reduction in maximum fiber direction stresses in the blades with the exploitation of off-axis plies in the main spar caps of the wind turbine blades. Wind turbine models ...
Damage Progression in Thick Curved Composite Laminates under Static and Fatigue Loading Tasdemir, B.; Çöker, Demirkan (IOP Publishing; 2018-06-22) In this study, damage behavior of curved carbon fiber reinforced polymer (CFRP) composite laminates that are important sub-structures (ribs, shear webs and spar flanges etc.) for wind turbine blades are investigated under static and fatigue loading conditions. Cross-ply curved specimen consisting of groups of three 0 degrees and 90 degrees layers is used for clear observation of the matrix cracking in thicker plies. Damage mechanisms and locations under static and fatigue loadings are examined. In the exper...
Aero-structural design and analysis of a joined-wing kit Alanbay, Berkan; Şahin, Melin; Department of Aerospace Engineering (2015) In this study, a multi-objective aero-structural multidisciplinary design optimization (MDO) of a joined-wing kit which is installed on a transonic free fall munition is performed. The main purpose of the joined-wing kit is to enable the munitions to extend their range and gain standoff attack capability. In order to fulfill these aims joined-wing kit configurations are generally investigated through various analyses. Each joined-wing configurations are determined through two geometric key parameters namely...
