Mit einem Resonator versehenes Blatt zur Reduzierung der Bewegungen im Strömungswiderstand dieses Blatts und Verfahren zur Implementierung dieses Blatts

摘要

The blade (10) has a resonator (20) for reducing drag movements of the blade, where the resonator includes a closed tank (30) partially filled with liquid (50). A central tube (40) is immersed inside the tank, where the tank and the central tube are arranged in a longitudinal direction (Y) of the blade. The central tube includes two ends (41, 42) communicating with the tank, so that the liquid moves between the tank and the central tube. The tank includes a set of ribs (33) for fastening the central tube to an inner side wall (38) of the tank. An independent claim is also included for a method for limiting drag movements of a blade.
