Modern rotor blade designs depend on detailed numerical models and simulations. Thus, a validated modelling methodology is fundamental for reliable designs. This paper briefly presents a modelling algorithm for rotor blades, its validation against real life full scale blade tests and the respective test data. The hybrid 3D shell/solid finite element model is successfully validated against the conducted classical bending tests in flap-wise and lead-lag direction as well as novel torsion tests.

Light detection and ranging (lidar), has become a valuable technology to assess the wind resource at hub height of modern wind turbines. However, because of their measurement principle, common lidars suffer from errors at orographically complex, i.e. hilly or mountainious sites. This study analyses the impact of the five main influencing factors in a non-dimensional, model-based parameter study.
