You mean for EMILIE?
To be honest, I do not trust any pulse-power numbers which are not made
with a dedicated power analyzer any more. It is too easy to fool oneself
with RMS calculations. This is why EarthTech will not even comment on
data made with anything else than their Clarke-Hess.
And also - this is why auto-rotation is so very important. No one can
doubt self-power - and there is no good excuse for not having self-power
with some of the numbers which can be guesstimated by what Terry
indicated. This should be a massive magnetic field.
BTW - in any such "ramp" design, where there is a sticky point and a
dedicated release magnet, I have made the contention before - and have
yet to hear an effective counter-argument against it - that the release
magnet, any release magnet, is a waste of time. They are all lossy.
If a properly designed flywheel will not provide the torque necessary
for release, then NO electro-magnet has a chance. Almost any flywheel
with a good thrust bearing will be 99% efficient, and I have yet to see
any pulsed electromagnet which is close to that. Go figure.
Not to mention - if you believe in the "Aspden effect" and it does seem
valid to a small degree, then the flywheel itself may be slightly OU in
a differential sense. That is to say, even if the net COP is than one in
total, as we all know to be true since there is friction and windage,
yet when the RPM range is within in a prime torque range for that wheel,
there could be a tiny differential leveling boost - say COP 1.01. This
would be ideal in that application.
I could probably explain that better, given time.
