    Patent number: 8096779
    Abstract: A rotorcraft blade (P) is provided in succession with a radial segment (1) and then a swept segment (2), the swept segment (2) being provided with at least one forwardly-swept segment (2?) and/or rearwardly-swept segment (2?). In addition, the blade has a single spar coming from the blade root. The invention is remarkable in that the single spar includes a radial spar (10) in the radial segment (1), after which the single spar splits where the radial segment (1) becomes the swept segment (2) to form thereafter in the swept segment (2) a primary spar (11) and a secondary spar (12).
