Wondering if anyone has information on the implementation of the driveshaft systems for the Stemme S10 or the P39 Airacobra? How do they address the torsional vibration issues? I would presume that the Stemme can get away with being really light, but what about the Airacobra? It seems like that would have been a pretty heavy and complex system, but I don't remember reading anything about it being particularly unreliable.
As a follow up, does anyone know what the TV is like on a modern automotive shaft like the Corvette C7's? With modern emphasis on reducing noise/vibration/harshness, I would expect that torsional vibration would have been looked at.
The reason I bring up the Airacobra are varied, but the simplest explanation is that I am dreaming about building a scaled replica, and would like to get more information on how one might approach the driveshaft.
I forget if this is 3/4 or 9/10 (I think it's 3/4), but you get a sense of the goal. The idea is for the pilot to be in a carbon tub, with the goal being survivability in low speed (<150mph) impacts in the case of takeoff/landing gone wrong. You can see there are two lines for the canopy, the lower one is the true to scale canopy, and the upper one is where I think it would be more comfortable while still looking "good enough".
