blades folding mechanism

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.
