Bladed provides worldwide wind turbine and component manufacturers, certification agencies, design consultants and research organisations with a design tool that has been extensively validated against measured data from a wide range of turbines. It enables users to conduct the full range of performance and loading calculations. With a Windows-based user interface, it supports calculations of combined wind and wave loading, with full aeroelastic and hydroelastic modelling. It has been validated by Germanischer Lloyd for the calculation of wind turbines loads for design and certification. Multibody structural dynamics Bladed utilises a new, completely self-consistent and rigorous formulation of the structural dynamics. This provides consistently reliable and accurate results and forms a solid foundation from which to continue to extend the structural model with features as part of the ongoing development programme.
