Patent

CA 2073406

A pitch control mechanism for a ram air turbine blade (4) comprises a mass (1) fixed to the blade shank (2) in a plane at an angle, to a pitch change axis (5). As the turbine rotates about the rotational axis 7, the mass (1) moves in the direction of arrows (11, 12) according to the speed of rotation varying the pitch of the blade (4). By directly coupling the pitch change mass (1) to the blade (4) the need for complicated linkages is eliminated.
