摘要
A twist mechanism for twisting a rotary-wing blade (2). A twist member (8) is movable by an actuator (11) of the centrifugal force type, which twist member has at least one flyweight (14) for driving a rotary member (13) about a pivot axis (A). The flyweight (14) is radially movable on the rotary member (13) by movement means. The centrifugal force FC to which the flyweight (14) is subjected as a result of the blade (2) being caused to rotate induces drive torque CM for causing the rotary member (13) to pivot, thereby causing the twist member (8) to be moved. The twist member (8) is in engagement with the blade (2) at its free end and is connected to the rotary member (13) via remote mechanical transmission means (12).
