The connecting arm; and flexible with flexion damping integrated, in particular for the connection of a rotor blade has its hub, and the rotor and the hub teams of such arm

摘要

The arm of the torsion and flexible connection with integrated flexion damping according to the invention comprises, between two rigid end portions, a flexible central part made of a peripheral beam 6 of the rods 8 of high-mechanical-strength fibers coated with a vulcanised flexible elastomer 9, and a damping core 7 to the central blade 13 of the shearing of a damping gel 12 having a tight and flexible bladder 11 embedded in the elastomer 9. / p & & p & to the deformations in the plane of the blade 13, that - ci shears the gel 12, which produces a damping is added to that resulting from the persistence of the deformation of the elastomer 9. / p & & p & application to the connection of two rigid bodies, such as a rotor blade to its hub.
