The aerodynamic load of the blade is mainly obtained perpendicular to the blade rotation plane, i.e. swing load . GHBladed is a specialized software for calculating aerodynamic load of wind turbine blade.
July 26, 2025 - The wind load on the wind turbine is monitored during the movement and impact of the tornado. Fig. 8 presents the load time history of the full rotor during the event. In particular, Fig. 8(a)-(c) illustrate the wind load in the x, y, and z directions, respectively, and Fig. 8(d) is the maximum and RMS values of the load time history, where the maximum load represents the largest magnitude, irrespective of the sign. As illustrated in Fig. 8, the aerodynamic load on the rotor undergoes
November 1, 2025 - It has been found that the wake interaction between the blades and the tower can strongly affect the aerodynamic forces on the wind turbine, which highly depends on the wind direction. Critical directions for wind load were found to be E, W, NW, and NE directions. ... Physical simulations on wind loading characteristics of streamlined bridge decks under tornado-like vortices
The tower mainly experiences horizontal loads. Key factors, including relative positions and the spatial configuration of the blades after shutdown, are crucial for understanding the tornado-induced loading on the turbine. The dynamic pressure response of the turbine is marked by a sharp decrease followed by a gradual recovery, reflecting the passage of the tornado.
August 18, 2020 - This section discusses the development of the HIW-WT (High Intensity Winds on Wind Turbines) numerical code. The presentation of this numerical code is divided into three parts: (1) the tornado wind field used, (2) the evaluation of the aerodynamic forces acting on the blades and the tower, and (3) the analysis procedure.
August 22, 2023 - The safety and reliability of wind turbine blades are increasingly challenged by extreme wind conditions such as typhoons, as wind turbines tend to become larger. Under these conditions, most units will be shut down and the blades will be pitched to around 90° to minimize the loads. This paper aims to compare a new strategy for the parked condition, i.e., the trailing edge windward state, with the traditional leading edge windward state to verify its technical feasibility. The aerodynamic loads of a 30%-thickness airfoil and a commercial wind turbine blade are comprehensively evaluated by wind tunnel experiment, CFD simulation and engineering analytical model.
April 30, 2025 - Furthermore, a computational model for wind turbine load calculations and real-time simulation in a hardware-in-the-loop environment has been developed. This model is programmed in the open-source object-orientated modelling language Modelica and is archived in a component-based library. The library contains models for structural components, aerodynamics, control, drivetrain, environment, and offshore wind turbine simulation.
May 22, 2025 - Researchers can use optimised blades to conduct various types of offshore wind turbine scale experiments more efficiently. This optimisation method can improve the accuracy and reliability of model experiments, providing technical support for the offshore wind turbine's design. To address this issue, a model or environment correction based on the wind and wave field characteristics is widely used to ensure that the aerodynamic load satisfies the Froude scaling requirement [19,20]. Currently, four primary solutions are adopted: utilising thrust discs, increasing the wind speed, increasing the roughness of model blades, and optimising the model blades.
