Didn't the French invent the Le Rhone Rotary engine - back in the days
of the bi-planes?
The Le Rhone was a radial engine - cylinders in a circle around the
crank. But unlike most other radials at the time. and even unto today,
this thing had the propeller bolted to the crankcase, and the crank
shaft mounted solidly to the firewall of the airplane. Now think about
the implications of that!!
With that much rotating mass the gyroscopic precession must have been
fierce.
