Abstract
A variable pitch aircraft propeller assembly includes: a plurality of propeller blades and at least one counter-weight arrangement mounted on a propeller blade. The counter-weight arrangement comprises: a first counter-weight and a second counter-weight. The counter-weights are arranged such that when the propeller blade is in fine pitch, the counter-weights are in a first position with respect to the plane of rotation of said propeller blade, and when the propeller blade is substantially feathered, the counter-weights are in a second position with respect to the plane of rotation of said propeller blade. The counter-weights are aligned such that a line drawn between the center of mass of the first counter-weight and the center of mass of the second counter-weight is substantially perpendicular to a longitudinal axis of the propeller blade.
