| titleOfInvention |
Rotor head having elastic, internally damped return devices between the blades |
| abstract |
The invention relates to a rotor head with interposed elastic return drag rods with incorporated damping, on which each tie rod (29) is connected to each of the two rotor blades which it connects to one another by means articulation comprising a main ball joint (41) retained on a member (13) connecting a blade to the hub (1), and centered on or in the immediate vicinity of the pitch change axis (XX) of the blade corresponding.n n n A single main ball joint (41) can be connected to the adjacent ends of two neighboring tie rods (29) by a V-shaped connecting piece (35) open towards the hub (1), or else each tie rod (29) is connected to a member of connection (13) by one respectively of two main ball joints offset transversely with respect to the pitch change axis (XX) of the blade and / or radially along this axis.n n n Application to main rotors and / or anticouples of helicopters. |
