Whoops!
Nick, what you say is informative and makes sense. Unfortunately, we have a problem.
Lu said,
"You got it wrong. If the pitch horn extends beyond the cone hinge when the blades cone pitch will be added to the blades not removed.
"Lu,
You got it right. I assumed (naughty, naughty) that your
" It has been brought to my attention that on the R-44 the pitch horn extends beyond the cone hinge by approximately 28mm.". meant that the pitch link was outboard of the coning hinge.
Burkhard Domke's picture confirms that the pitch link is actually inboard.
This means that on the R-44, upward coning adds pitch and upward teetering removes pitch. Therefore, much of what Lu says makes sense. In addition, Steve76's comment
" They better rethink the Delta 3 application for the R44 if they think that it helps to make it more stable in turbulence..." also appears to support this position
Frank R. must have had his reasons for moving the pitch link inboard of the coning hinge but it appears to be counterintuitive to the thinking of those on this forum, and Chuck Beaty. This sure make Lu's concerns a lot more interesting.
