BLADE AND METHOD OF FABRICATING SAID BLADE

摘要

PURPOSE: A blade and a manufacturing method thereof are provided to obtain optimal strength and to make a part for connecting to a hub to be exposed. CONSTITUTION: A blade comprises a coupling part, an airfoil element, and a torsion force transmission member(40). The airfoil element has a spar longitudinally extended from an attachment part(21) toward the end part. The attachment part surrounds a centrifugal force transmission bushing with a through-pin. The torsion force transmission member comprises a first half shell(41) and a second half shell(42). The first and second half shells surround the attachment part.
