  • Washout base on flybarless head

    I was drooling over pictures of a 700le flybarless the other day and thinking about how it works got me confused.

    The swash plate has 4 ball links just like a standard flybarred swash, but only 2 of them seem to be linked to the blades (they go directly to the blade holders).

    The other 2 go to arms on something that looks like a washout base. But then nothing appears to influence the blades from there on.

    What is the point of this part of a flybarless head? Does it apply damping or something? That is all I can think of, but I am not sure why it would need it there.

    Cheers,

    Andrew

    Just stops the upper part of the swash rotating

      It locks the swash ensuring the control rods are exactly 90 degrees to the blade grips. This is important for correct phasing.

      Hope it helps

        I don't understand that. Stops it rotating how? In which plane?

            Yes, I see now. I sort of feel silly for asking the question.

                No, it was ok. I had actually assumed that you meant that, but I couldn't see how it actually did stop rotation like that.

                It looks like it is free to move in relation to the head block and, crucially, rotate around the shaft.

                Now I have looked at the pictures again, I am still confused because of that.

                Does it clamp onto the shaft?

                  Yes it clamps to the main shaft to allow you to set the phasing.
