The aircraft I am interested in is the G802 Orion, designed in France in the
80's. It had problems with a long drive shaft and so I am interested in how
others have solved a similar problem. It also incorporated a Flexidyne type
coupler but it still had problems.
I work in aviation but there isn't a lot of good suggestions (printable)
from the people and engineers I work with.

Look up Molt Taylor and his Aerocar system. He used a pusher
arrangement and seemed to have most of the problems solved with long
shaft back to prop.

His bird may still be flying some place to exhibitions?

Am sure someone will jump in here and give data on his bird and how he
coupled shaft to engine with a "power glide" clutch or some such. It
allowed a small amount of slippage at each power stroke to prevent the
pulse being transmitted to drive shaft and prop as I recall.

Best of luck with a difficult problem.

Ok,

I think it's also used on the Imp and Mini-Imp.


The "clutch" consists of two (wavy surfaced) plates with lead shot
loaded between them.

As the thing spun up, centrifugal force packed the shot solid, but
there was enough "give" with the shot to absorb the "jerk" (4th
derivative?).

no idea why that came out in past tense...
