ABSTRACT:
A method facilitates lubrication of components. The method includes coupling a blade to a pitch control mechanism such that a bearing is positioned between the blade and the pitch control mechanism. The method further includes coupling a control system to the pitch control mechanism and configuring the control system to control the blade pitch mechanism for controlling movement of the blade and rotate the blade from a first position to a second position when a predetermined amount of time has elapsed.
