Title: Dynamical Stresses in the High Class Wind Turbine Blades caused by the Vertical Wind Gradient. Part 1: Aerodynamical Loads
Keywords: Aero-dynamic loads, Vertical distribution and longitudinal turbulence of wind, Wind turbine

Abstract: For the powerful wind turbines having large dimensions, the aerodynamic interaction becomes a function of the angle of the turbine rotation (azimuth angle), due to the impact of the vertical gradient of the wind speed. This distribution is as a result of a multitude of a tribological and thermodynamics factors. The authors of this study in previous researches showed that this results in significant dynamic loads on the turbine blades. Furthermore the longitudinal turbulence of the wind speed introduces additional dynamic excitation. The investigation of these dynamic loads is the main objective of this study. © 2019, Scibulcom Ltd. All rights reserved.
