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.

Kinematic analysis of combined mechanical systems of simultaneous blades turning and folding of horizontal-axis wind turbines.

Various types of combined mechanisms of simultaneous blades turning and folding, which can be used for power regulation and rotation frequency stabilization of horizontal-axis wind turbines, are examined. Kinematic diagrams of certain mechanisms are designed. Analytical expressions for ascertainment of regulation sliders displacements from turning and folding angles are deduced.
