Blade and method for manufacturing said blade

摘要

The blade has a twisting force transmission element (40) provided with half-shells (41, 42) that surround an attachment zone (21) of a spar of an airfoil element. Each half-shell has a first set of portions (43', 43'') providing visual access to a centrifugal force transmission bushing when the airfoil element is removed from a fitting and a second set of portions (44', 44'') co-operated with a torsion box surrounding a distal zone of the spar. The transmission element is secured to the fitting in rotation around a torsion axis of the blade. An independent claim is also included for a method for fabricating a blade.
