Now that we are all reading from the same sheet of paper I have several questions.
1) The attachment ears on the rotating ball joint connect with the longitudinal and lateral inputs. At what angle do these two attach points intersect?
2) Are the longitudinal and lateral inputs aligned with the respective axes of the helicopter? That is, is the longitudinal input aligned with the longitudinal axis and is the lateral input aligned with the lateral axis of the helicopter?
3) What is the maximum deviation of the rotating ball joint from its’ point of neutrality in any given direction when cyclic input is made?
4) From the Prouty diagram the rotating ball joint seem comparatively small. How big is it?
5) Is the rotating ball joint a high maintenance item? It would seem that if it fails you would lose all control of the helicopter. This has happened on Aerospatial helicopters when the swashplate bearings locked up with disastrous results.
6) The Prouty diagram shows the inputs to the rotating ball joints as control rods. Do the servos connect directly to the rotating ball joint or, are they rods as shown in the diagram?
7) In the picture of the Lynx rotorheads it seems that the pitch horns lead the blade by what appears to be 45-degrees. Is this correct?
Once I have the answers I will return with more questions. This should take up a lot of your spare time.
