Great minds think alike! I'm in the process of fabricating such a gap
only with a few modifications. I'm using 3/8" tungsten rod
stationary contacts that I hope to drill 1/4" holes in and supply
pressure (possibly inert gas) to. However, I'm not using a
sandwich rotor, I'm just using composite fins on the contact side of the
rotor. The center of the rotor is fed with a 3" PVC pipe
1/4" from the vanes. The input to the PVC is fed by a fan (positive
pressure). There is a composite baffle that has two 2" hole
drilled for the stationary contacts. This in line with the vane
turbulent outward flow of air to cool the rotating contacts should
provide good quenching. Maybe to good? A friend of mine is looking into
the type of composite that we are going to use. The
airflow should be great enough to cool it significantly.... I'll post
pictures when we get close.

Though I havetn't actually made one of these things yet Ive been trying
to think of optimal designs.
These are some thoughts that I have had that I havent seen before or
heard of from anyone on this list yet so I thought I would throw them
out there for general consumption and feedback;
a - turbulent air flow over the points seems to be an advantageous
thing, why not alternate non conductive fins or vanes with the points on
the rotor such that after each point fires the atmosphere in the
immediate vicinity is forcibly disturbed.
this then led to
b - possibly even better, yet more difficult to construct, a sandwich
rotor, something like a vented disk brake. each side of the rotor would
have a smaller diameter plate attached to it by radiating vanes. the
inner diameter of this sandwiched plate would be larger than the axle,
allowing for intake.
this would be like sandwiching a rotary spark gap and two centrifugal
fans. Each contact on the rotor could be alloted its own 'jet' so that
it was constantly being cooled. And the stationary points would have a
constant blower accross them as well. Thus the 'blower' operation would
be instrinsic to the operation of the rsg.
I hope i described this well enough that you can see it without
drawings.
any thoughts? Has this been tried?
