Energy Science &Engineering, Volume 13, Issue 4, Page 1457-1477, April 2025.ABSTRACT This study investigates and assesses two different strategies for the design of wind turbine blades, consisting of two components: the external shell made of carbon fibre‐reinforced epoxy and the internal beam. The first strategy is based on designing the blade through the selection of the beam material.

Wind Turbine Stall‐Induced Aeroelastic Instability Mitigation Using Vortex Generators
Wind Energy, Volume 28, Issue 4, April 2025.ABSTRACT Inspired by Vortex Generators' success in delaying airfoil stall, this study explores the potential of using Vortex Generators to mitigate stall‐induced instability in floating offshore wind turbines at parked and skewed inflow conditions for the first time. Significant improvements are achieved by strategically installing Vortex Generators in

Advanced Engineering Materials, Volume 27, Issue 2, January 2025.Uncertainty quantification (UQ) of aerospace microstructures: state‐of‐the‐art studies on UQ of microstructures in aerospace materials are examined. The forward problem of uncertainty propagation in process–structure and structure–property relationships is investigated. Additionally, the inverse UQ problem, referred to as “design under uncertainty,” is

Bridge Flutter Prediction and Active Control Using Modal Information and Flutter Margins
Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.In this paper, a flutter prediction method based on flutter margins is proposed for streamlined bridges whose aeroelastic behavior can be well approximated by a two‐degree‐of‐freedom (2‐DoF) flutter model. The method enables prediction of the flutter boundary by extrapolating a curve of flutter margin versus wind speed, constructed using flutter ...

Advanced Aerodynamic Technologies for Future Green Regional Aircraft
INCAS Bulletin, 2014 Future Green Regional Aircraft (GRA) will operate over airports located in the neighborhood of densely populated areas, with high frequency of takeoff/ landing events and, hence, strongly contribute to community noise and gaseous emissions.

Blade Surface Pressure Measurements in the Field and Their Usage for Aerodynamic Model Validation
Wind Energy, Volume 27, Issue 12, Page 1483-1498, December 2024.ABSTRACT This study presents results from a long‐term measurement campaign on a research wind turbine in the field. Pressure measurements are conducted at 25% blade radius over several months. Together with inflow measurements provided by a LiDAR system, they form an extensive dataset, which is used in the validation of numerical aerodynamic models ...

High Specification Offshore Blades. Work Package: 1C – Blade Materials. [PDF]
, 2008 Blades are regarded as the only component unique to wind turbine blades. They represent only 10 – 15% of the total system cost so the perception is that a reduction in the cost of energy through blade cost improvements is constrained.
