tip path plane
I've reserved the 'tip path plane' label for the illustration of coning angle in relation to the Plane of Rotation, which may or may not be the same as the Plane of Rotation relative to the Shaft Axis.
So i have been trying to segregate tip path plane from anything else. As I will also need to illustrate the difference of the disc area formed by the tip path plane during coning, in comparison to tip path plane in an otherwise 'normal' AoR.
by 'normal' i infer that the disc area is at its maximum, & coning is angle is zero
an AoR 'datum' would need to include a Plane of Rotation 'datum', so that as with the AoR vs Shaft Axis, the Plane of Rotation relative to each of these is illustrated (i think i've cocked up the explanation of that in the opening thread - apols)
the Plane of Rotation relative to the AoR will be the significant feature of the animation, it will also serve as a reference datum for the coning part of the animation
cheers
