Jeez...that's something I've never considered. You are RIGHT, internal
to that
alternator there IS 3-phase AC that is regulated and rectified to
produce the
DC...

And now with three small transformers and a little surgery on the
alternator, we
could have 3-phase 115VAC to run those military gyros...I wonder...yeah,
I know
the frequency is a function of engine RPM...but still...

You think that AC coming out of those inverters is all that stable? It
tends to wander
with the input voltage. Of course the real problem is that if the
alternator crumps, the
battery will not put out three phase.


What?!? Your plane doesn't have 3-phase batteries? Call CBS!
