bugdevheli;
Has anyone else tried out this concept
Since you asked:
I once considered developing a control arm that acted like a snake. It had 3 compartments with flexible walls mounted radially about the central longitudinal axis of the arm. This set of three compartments was repeated many time down the length of the longitudinal axis. The motion of the 'arm' was to be controlled the volume of fluid that was inserted or extracted from each of these compartments.
Your idea:
I assume that you may be thinking of threading tubes into the diagonally laid-up flexible skin (fiberglass) of the blade to provide active blade twist. And/or spanwise tubes to change the profile or camber of the blade. If so, it might just work.
