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 in succession along an axis of extension (X) a body portion and a distal connection section and a distal section. The blades form at least a wide laminated member (8) and a narrow sheet element (6, 7). The body sections are identical and superimposed at a body (11) of the torsion bar. Said distal portions are superimposed and identical to a distal clip 13. Each distal connection section of a blade of a wide laminated member (8) projects laterally relative to the distal connection section a blade a narrow sheet element (6, 7).
