Abstract
The shielding of the blade against lightning comprises a conducting component forming a leading edge glove and a cover for protecting the blade tip across its entire chord. Mechanical means, such as screws and rivets, with protruding shapes, fix the cover on the composite structure of the blade, in addition to some gluing, possibly conductive gluing, and are earthed by the cover, forming points where the lightning can enter or exit, protecting the surrounding composite structure of the blade against damage. At least the cover may have a suction face arm and a pressure face arm of different dimensions, at least in the direction of the span. When the blade is mounted on a member for linking to the hub, electrical continuity with this member and the hub is provided.
