There is a lot of concern about torsional vibration. The reason why springs don't do the trick is because all they do is store the energy and then release it again at their own frequency...and the springs will fail quick due to the high cycle rate. The ideal damper woud work just as shock strut does; it absorbs the impulse energy, then releases it slowly. The problem is that we don't have anything that can do that that is adaptable to a piece of rotating machinery.
Another way to dampen impulses is with shear mass...dead weight. I realize that dead weight = dirty word in aviation. A manual tranny flywheel will take a lot of fight out of the torsional vibration. A manual flywheel is awfully heavy, so how about a custom flywheel of a larger diameter to achieve a greater moment arm but of lighter weight...all the weight at the outside diameter.
Any thoughts on that?
