Abstract

A method of fabricating a spar for a blade, which spar includes transversely at least one arrangement. A male former is defined for each arrangement that is to be fabricated and each arrangement is subdivided into a pressure-side subassembly and a suction-side subassembly, each comprising a plurality of hanks, each hank comprising a plurality of U-shaped tape segments stacked on one another. Each subassembly of an arrangement is fabricated outside a mold for fabricating the blade on a single former adapted to that particular arrangement, fabrication being by stacking tape segments on the former using a fiber placement method implemented by a placement head.
