In the conversion of wind power, the rotor is the first point of energy transformation, transforming the kinetic energy of the wind into torque and rotation. Rotor technology sets a limit of the energy converted and the loading required to convert this energy. The load cycles are design drivers, influencing the mass and operation of the rotor, and therefore the entire turbine. In addition to extracting kinetic energy from the flow, the rotor creates a pressure field that generates the wake and leads to noise generation. Rotor design optimisation must therefore account for power and load optimisation, constrained by the full lifecycle, fatigue life and noise, among other boundary conditions. This session focus on innovations in both rotor design methodologies and components.
