Structural design optimization of the controllable rubber trailing edge flap (CRTEF)

A flap actuation system, the Controllable Rubber Trailing Edge Flap (CRTEF), for distributed load control on a wind turbine blade had been developed in the period from 2006 to 2013 at DTU. The purpose of the project is to optimize the structural design of the flexible part of the CRTEF based on a realistic blade section geometry in order to meet...

Investigation of Root Spoilers on Horizontal Axis Wind Turbines

For the purpose of flow analysis, the blade of a horizontal axis wind turbine (HAWT) can be divided into the root, mid and the tip regions. The flow in the root region is very complex and is affected due to the rotation of the blade and separation due to the presence of very thick airfoil sections and the higher angle of attacks. Hence, a...

An innovative approach towards solving the problem of trailing edge buckling of large wind turbine rotor blades

As a result of the increasing mass of rotor blades for large wind turbines, trailing edge buckling is recognized to become one of the critical design drivers. This research project was initiated to investigate a new trailing edge design concept, which is supposed to have a higher buckling capacity, while maintaining its structural performance,...

Increased Energy Yield using the Smart Rotor: Sizing and Control of Trailing Edge Flaps on a Smart Rotor for Maximum Power Generation in Low Fatigue Wind Regimes

A Comparative Analysis of the Two-Bladed and the Three-Bladed Wind Turbine for Offshore Wind Farms

Background: As the installation of offshore wind farms continues to increase, the need to optimize on costs involved is a constant factor in the industry. In this regard, research into the two-bladed rotor has garnered some interest in the recent past, to see if the optimum cost can be shifted in the favor of the two-bladed wind turbine....
