The results of numerical simulation and analysis of the dynamic behavior of the rotor blades of horizontal axis wind turbines are presented. The blades are made of different composite materials with different stacking layups. This type of wind turbine is dominant in modern high-power wind energy plants, and its dynamic characteristics should be carefully studied. For this purpose, the computer models of rotor blades with composite skins with different structures and stiffeners are developed and studied using the finite-element method (FEM). Based on these models, the modal analysis of turbine blade vibrations is carried out, and the benchmark cases for the dynamic response under a uniform sine-pulse pressure applied to the underneath part of the blade are investigated through finite-element calculations.
