<p>PURPOSE: A rotor blade is provided to facilitate visual inspection for maintenance and to optimize the strength of a section freely connected to a hub. CONSTITUTION: A rotor blade(1) has a fitting and an aerodynamic element. The aerodynamic element has a main spar(20) extended from an attached section(21). The attached section is connected to the fitting and surrounds a blushing to transfer centrifugal force. The blade comprises a transfer member to transfer torsion force. The transfer member comprises a first half-shell and a second half-shell. Each half-shell has a first part cooperating with the blushing; and a second part cooperating with a torsion box(50). The fitting is inserted into the first part.</p> |
