Item 1333

DESIGN: SynchroLite ~ Rotor - Hub - 3-blade - CVJ & HS - Layout (previous)

Drawing: This drawing is just of one idea. Note that inserting the radial torque bearings into the area of the vertical shims looks like an improvement. Note also that this whole Idea may not work because the elastomer between the vertical shims might be subjected to expansion.

Note:

The small radial bearings are to allow the hub plates in the torque bearing to rotate +/-12º as the head teeters.

This is functionally similar to the Sikorsky patents 4,714,450 and operationally similar to the Bell patents 4,729,753 OTHER: Flight Dynamics - Rotor - Hub - Elastomeric CVJ - Patents

Problem ~ As the device teeters the circumference of the torque elastomer will increase.

Stiffness of the Elastomers/Epoxies:

Thoughts:

Consider the possibility of an elastomeric Bendix Constant Velocity Joint. The center ball, of the five, is used for positioning the two halves of the joint and for an elastomeric CV joint the spherical elastomer will do the same thing.

Consider means to replace the four other balls, such as;
  1. three, four or many tapes of metal or composite wrapped spirally at the plane of pivoting; or
  2. a number of elastomers located between arms on the shaft (ball) and the rotor hub.
