TORSIONALLY FLEXIBLE BEAM FOR A BLADE, SET OF TORSIONALLY FLEXIBLE BEAMS, A ROTOR AND AN AIRCRAFT

摘要

The present invention relates to a torsion beam (1) comprising a plurality of blades stacked on each other. Each blade comprises successively along an extension axis (X) a body section and then a distal connection section and a distal section. The blades form at least one wide laminated element (8) and a narrow laminated element (6, 7). The body sections are superimposed and identical at a body (11) of the torsion beam. Said distal sections are superimposed and identical at a distal attachment 13. Each distal connecting portion of a blade of a wide laminated element (8) is projecting laterally with respect to the distal connection portion of a blade. a narrow laminated element (6, 7).
