Don’t know if it has any bearing on the topic, but one thing to note is
that the rotary is much easier on the gear train. There are no torque
reversal regions in its cycle as there are with piston 4 stroke engines.
Also the power impulse is a bit smoother (covers more deg of rotation) than with
a piston engine. So what may survive with the rotary, may not with a
piston engine. Tracy has certainly studied this area and will undoubtedly
have more astute observations.

Subject: [FlyRotary] Spline failure on Egg Sube
PSRU
I have the NTSB report
on the PSRU failure for the Subes. The file is too large ~700 kb to send
to the list. Anyone interested can email me and I will send them a
copy.
I am wondering if there
are there any things we can learn about our PSRUs from this? Does this
spline failure bring any ideas for inspections that we perhaps should do?
Tracy??
