Abstract: An integrated transmission and helicopter rotor head is disclosed. Lift and bending moments generated by the rotating hub are carried by non-rotating support structure. The rotating rotor shaft is adapted to carry only torque loads. Partial gear reduction takes place above the rotor shaft, thereby reducing its torque loading. The invention includes a planet gear assembly wherein the ring gear is connected to the rotating hub, while the rotor drive shaft causes rotation of the sun gear. The hub swashplate is located above the hub with its control rods passing through the planet gear assembly.
