Aeroelastic analysis of an offshore wind turbine: Design and Fatigue Performance of Large Utility-Scale Wind Turbine Blades
Fossum, Peter Kalsaas (Master thesis, 2012)Aeroelastic design and fatigue analysis of large utility-scale wind turbine blades are performed. The applied fatigue model is based on established methods and is incorporated in an iterative numerical design tool for ... -
Aeroelastic Instability and Flutter for a 10 MW Wind Turbine
Vatne, Sigrid Ringdalen (Master thesis, 2011)The goal of this thesis is to evaluate if flutter is a challenge to a 10 MW wind turbine. Flutter is an aeroelastic instability which occurs due to the interaction between the aerodynamic forces and the elasticity of the ... -
Characterization of Aerodynamics of Small Wind Turbine Blade for Enhanced Performance and Low Cost of Energy
Kelele, Hailay Kiros; Frøyd, Lars; Kahsay, Mulu Bayray; Nielsen, Torbjørn Kristian (Peer reviewed; Journal article, 2022)During a turbine’s lifetime, minimizing the cost of power production should be the primary aim in addition to attaining high technical efficiency. Thus, this paper was aimed at enhancing the aerodynamic efficiency of a ... -
Control System on a Wind Turbine: Evaluation of Control Strategies for a Wind Turbine with Hydraulic Drive Train by Means of Aeroelastic Analysis
Frøyd, Lars (Master thesis, 2009)The evolution of wind turbines are going towards floating offshore structures. To improve the stability of these turbines, the weight of the nacelle should be as low as possible. The company ChapDrive has developed a ... -
Design and Dynamic Modeling of the Support Structure for a 10 MW Offshore Wind Turbine
Crozier, Aina (Master thesis, 2011)This thesis presents two designs of tension-leg-platforms (TLP) support structures for the 10 MW reference wind turbine being developed by the Norwegian Research Centre for Offshore Wind Technology (NOWITECH). The designs ... -
