Above: general outline of concept
Above: Top view, aft
Above: Aft pylon w/ RDCP (JM2G) for lateral tilt and power plant airframe for aft pitch control
Above: generic view of aft power plant airframe. Not all bracing shown. Airframe radius guided track is not complete.
Above: Intermediate power plant drive train and lateral "spherical slide" bearing assembly. Sphere is stationary and rotor mast revolves at RPM within sphere inner diameter. Functions similar to the "A" frame of a car, but a bit different. Allows power train to flex without back lash as RDCP tilts laterally.
Above: a closer view of the spherical slide bearing assembly. I rush the sketch, so all of the art inclined folks do not need to tell me that the mast is not parallel to the inner diameter of the sphere...lol
