With no swashplate as used on conventional helicopters how do you get input from the stationary servos via the push pull tubes to the rotating elements of the dynamic system? Is the so called spider arm in effect a swashplate?
Regarding your diagram, I find it difficult to understand for several reasons.
1) What is the significance of the numerical scale at the left of the diagram?
2) What is the difference between the desired input and the required input?
3) Does the dotted line indicate blade flapping as a result of pitch input?
Regarding the power (interlock) of a rigid rotor helicopter I saw it demonstrated by a Lockheed 286 when I was working on the Cheyenne. In fact on the Cheyenne the cyclic was locked out while the helicopter was on the ground. The interlock was so strong that the helicopter could be tipped over if the cyclic was moved.
On the Super Lynx rotorhead they have lead lag dampers. Did they incorporate the capability to lead and lag to minimize the stresses on the blades and the rotorhead?
