Abstract:
In order to eliminate or at least to reduce a possible unbalance of the propulsive system, counterweights are brought in locations that are provided on the hub envelope, near the ends of the latter and away from the planes of the propellers. More particularly, the counterweights are provided as discrete elements located in two planes spaced from the propellers and orthogonal to an outer surface of the hub envelopes, or are provided as a non-uniform mass ring.
