STRUCTURE PORTEUSE D'UN ROTOR, ET APPAREIL VOLANT MUNI D'UNE TELLE STRUCTURE PORTEUSE

摘要

#CMT# #/CMT# The structure (40) has a mounting structure (8) equipped with an anti-coupling mechanism (10) damping vibrations for avoiding coupling of vibration modes of the structure and vibration modes of a rotor (20). The mechanism has a resonator (11) with a weighing element (13) that is element carried by the mounting structure via a deformable unit (14) retaining mobility of the weighing element. The mechanism is arranged on a base of a case (50'). #CMT#USE : #/CMT# Bearing structure for a rotor of a flying apparatus (claimed) e.g. aircraft such as airplane and helicopter. #CMT#ADVANTAGE : #/CMT# The design of the bearing structure ensures to fight against phenomenon of coupling of unstable vibration modes of the bearing structure in a simple and inexpensive manner. The bearing structure is easily implemented on the flying apparatus. The mechanism has the resonator with the weighing element that is element carried by the mounting structure via the deformable unit retaining the mobility of the weighing element, thus reducing encumbrance and weight of the bearing structure while ensuring optimization of attenuation of the vibration induced by movement of the rotor. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a flying apparatus with a bearing structure and a rotor. 8 : Mounting structure 10 : Anti-coupling mechanism 11 : Resonator 13 : weighing element 14 : Deformable unit 20 : Rotor 40 : Bearing structure 50' : Case.
