摘要

The control weight (4) on the rotor blade of the tail rotor of a helicopter is assembled from an inner weight (41) and an outer weight (42). The inner weight is installed on a support arm (31) and movable in the axial direction of the arm, and the outer weight is rotatable on the inner weight in screw fashion and therefore movable in the axial direction. At least one of the two weights is eccentrically installed in relation to the longitudinal axis of the support arm.
