Abstract
The present invention relates to a rotorcraft blade (1) provided with a dynamic balancing system having a balancing device (10). The balancing device (10) is embedded in the inside (INT) of the body of the blade (1) in such a manner that it does not open to the outside (EXT) of said blade (1).
Claims15
A rotorcraft blade (1) provided with a balancing device (10) of a dynamic balancing system, wherein said balancing device (10) is embedded in the inside (INT) of the body of the blade in such a manner that it does not open to the outside (EXT) of the blade (1), said balancing device comprising at least one heavy element (11) suitable for being moved remotely and without contact along a chord (CO) of the blade (1), and said heavy element (11) is provided with locking means (40) enabling it to be held in a fixed position.
A method of achieving dynamic balancing of a rotorcraft blade (1) provided with a dynamic balancing system having a balancing device (10) embedded in the inside (IN) of the body of the blade (1) in such a manner as to make no contact with the outside (EXT) of said blade (1), in which method a rotary magnetic field (30) is generated with the help of control means for causing a heavy element (11) of said balancing device (10) to move along a chord (CO) of said blade (1).
