Hello guys,
I stumbled on a very interesting design about a STOL aircraft: the Dornier Do-29:
https://en.wikipedia.org/wiki/Dornier_Do_29 I really like the setup but I was wondering how do you transmit the power from the engine to the prop.
I thought about a universal coupling, but I read on a manufacturer website that such joints are limited to small angles, whereas in this case the shafts can (theoretically) rotate up to 90 degrees. Wiki reports of successful testings of up to 60 degrees, which isn't that small.
So, how did they do it?
Thanks!
