The present invention relates to a rotorcraft blade () provided with a distributed spar () on a leading edge (), a suction side (), and a pressure side () of the blade, and the invention also relates to a method of fabricating such a spar. The blade is provided with a fastener insert () integrated in the blade root for the purpose of fastening the blade to a rotor, the fastener insert () comprising a horizontal shaft () perpendicular to the span of the blade and to an axis of rotation of said rotor, with the distributed spar () of the blade being wound in part about the horizontal shaft.

Blade provided with a horizontally-wound spar, and a method of fabricating such a spar

A rotorcraft rotor blade () has a blade root (') and a free end opposite from the blade root (&#x2032;), the blade () being provided at least with a spar () laid flat on a suction-side face () and a pressure side-face () of the blade (), the main spar () being secured to an attachment fitting () at the blade root (&#x2032;). The attachment fitting () then includes first and second horizontal fastener bushings (), the first and second fastener bushings () being both perpendicular to the span of the blade () and substantially perpendicular to an elevation direction (Z) that is substantially parallel to gravity (W), the elevation direction (Z) being perpendicular to the span.
