초록

According to the invention, at least one of the counterweights (40, 40.1, 40.2, 40.3, 40.4) is mobile mounted on a guiding slot (24, 34) coaxial to the hub envelope (22, 32) that surrounds the hub (21, 31) of the corresponding propeller (2, 3), the movement of said mobile counterweight (40, 40.1, 40.2, 40., 40.4) along said guiding slot (24, 34) being controlled on the basis of an estimation of the possible unbalance of said propulsive system (1).

청구항

1. A balancing method for a propulsive system with at least two coaxial non streamlined contra-rotating propellers, each of said propellers comprising a hub concentrically surrounded by a hub envelope and each of said hub envelopes being provided with an external wall, said balancing method according to which, to eliminate, or at least to reduce a possible unbalance of said propulsive system, counterweights are arranged on places provided on the latter, wherein at least one of said counterweights is movably mounted on a guiding slot being coaxial to the ...
