Multiple-yoke main rotor assembly |
| 摘要 |
The present application includes a main rotor assembly for an aircraft. The rotor assembly has a main rotor mast configured for rotation about a mast axis and two yokes pivotally connected to the mast for rotation therewith about the mast axis. Each yoke is independently pivotable relative to the mast about at least one flap axis that is generally perpendicular to the mast axis. In at least one embodiment, a torque splitter connects the yokes and allows for limited rotation of the yokes relative to each other about the mast axis. Each yoke is configured for the attachment of rotor blades extending generally radially relative to the mast axis. |

1. A main rotor assembly for an aircraft, the rotor assembly comprising:
a main rotor mast configured for rotation about a mast axis; two yokes pivotally connected to the mast for rotation therewith about the mast axis, each yoke being independently pivotable relative to the mast about at least one flap axis generally perpendicular to the mast axis; a torque splitter connecting the yokes and transferring torque from the mast to the yokes, the torque splitter allowing for limited rotation of the yokes relative to each other about the mast axis; wherein each yoke is configured for the attachment of rotor blades extending generally radially relative to the mast axis. |
