FLUID TURBINE HAVING IMPROVED CAM AND FOLLOWER MECHANISM

摘要

A fluid turbine comprising a blade pitch control mechanism comprising a cam and at least one rocker assembly, each rocker assembly comprising a rocker arm operable to pivot about an axis of rotation, the blade pitch control mechanism being operable to control the pitch angle of at least one rotor blade about its pitch axis and to vary the pitch angle of the rotor blade from a first pitch angle at a first circumferential location about the axis of rotation to a second pitch angle at a second circumferential location about the axis of rotation.
