These extreme loads - gusts, for example - occur within fractions of a second and require dynamic control. For this purpose, the relevant loads are measured so that they can then be actively influenced with suitable actuators. These can be air force actuators, for example, as extreme loads are largely caused by changes in aerodynamic forces. The development and validation of models of transient aerodynamics for fast air actuators, especially for controller design, is one of the main tasks. The project also promises a deeper understanding of the interactions between fast air actuators and the aeroelasticity of wind turbines. At the same time, the project aims to reduce the cost of mechanical components, which account for a large proportion of the total investment.
