TEST MEMBER FOR MODELING A BLADE OR BLADE OF A ROTOR, ROTOR COMPRISING SAID TEST MEMBER

摘要

The invention relates to a test element (20) for modeling a blade (2) or a blade of a rotor (1), the test element (20) comprising: - a support (21) comprising : • a lower part (22) modeling a blade root or blade root, • an upper part (23), - a balancing element (30, 40) fixed to the upper part (23) of the support ( 21); the test element (20) being characterized in that the balancing element (30, 40) is deformable so that when the test element (20) is mounted on a rotor (1) having a blade (2) or a blade, the center of gravity of the test element (20) changes according to the speed of rotation of the rotor (1), the center of gravity (CG20) of the test element (20) and the center of gravity (CG2) of the blade (2) or the blade being symmetrical with respect to the axis of rotation (X) of the rotor (1)
