A Ring Around Your Wings

[Dave_Jackson]

A sobering thought;

• Place a shaft inside your hollow mast.
• Drive this shaft in the opposite direction from that of the mast.
• Locate a planetary gear-set at the top of the mast.
• The shaft drives the sun gear.
• The hollow mast drives the planetary gear holder.
• A circular mass is attached to the outside of the ring gear by a universal joint.
• A strong swashplate is attached to the bottom of the circular mass.
• Two rod extends down from this swashplate to the root of each of the two blade.
• The blades are given hub-springs.

--------------------

• The circular mass provides the increased inertia.
• Plus;
• The weight of the inertia can be lighter because of its very high rotational speed.

• Plus, Plus;
• The craft now has greater cyclic control due to the moments created by the hub-spring on the rotor and the teetering of the rotating mass.

Now to join you.
