A MONOLITHIC BLADE A ROTORCRAFT ROTOR FITTED WITH SUCH A MONOLITHIC BLADE AND AN ASSOCIATED ROTORCRAFT

摘要

The present invention relates to a monolithic blade (21) of a rotating wing rotor, wherein the blade (21) comprises an airfoil zone (30) having at least a pressure side surface and a suction side surface at least locally. The invention is characterized in that the blade (21) comprises a root zone (3) comprising fingers (24) with a spherical bearing surface disposed at the root end (33) of the blade (21) And a flexible portion 26 having a preferred deformation direction when bent around a flapping axis of the blade 21. The flexible portion 26 is located between the fingers 24 and the recess 21, 23). / RTI
