>"Response: I meant that if you were to scribe a virtual line from the centerline of the cone hinge for two feet and at that point attach the pitch link to the pitch horn. As long as the attach point remains coincident with the centerline of the cone hinge and the blade flaps there will be no pitch change. "<

I agree.


>"However if the connection point is raised and is no longer coincident with the cone hinge there will be a pitch change and in this case pitch will be extracted. "<

I agree.

I agreed with this in my post 04 December 2001 20:54. It does not mater if the flapping hinge offset is 2" or 2'. Please note; I also suggested that you sketch out the action that you are talking about. You will find that the amount of pitch, which is removed by flapping, is very very minimal. In fact the word 'inconsequential' might be more appropriate.


Hold on Lu. There is no desire or ability to go into anything else until this one point is established.

The Edit:

Having reread your last two paragraphs, I agree that the cyclic change we are talking about will be similar to your analogy with the Bell.

I agree to nothing more

A question; how big a problem is this with the Bell?

A second question; What is going to make the Robinson's amount of flap/cone be anywhere near as great as the Bell's amount of teeter?
