Kinematic Analysis of Centrifugal and Aerodynamic Mechanisms of Blades Turning and Folding of Horizontal-Axis Wind Turbines
Various types of blades turning and folding mechanisms, which may be used for power regulation and rotation frequency stabilization of horizontal-axis wind turbines, are considered. Kinematic diagrams of corresponding mechanisms are constructed. Analytical expressions for calculating of regulation slider and centrifugal weights displacement as a function of blades turning angle are deduced. The recommendations for determining of their kinematic parameters (analogues of velocities and accelerations) are presented.
