Following the recent discussion about fans in high-temperature environments, might it be possible to use a bladeless fan inside a hybrid to generate turbulence and decrease burn time? This should explain what I'm referring to. Some hybrids already use high-voltage ignition systems that may be able to power such a device.
I think it might be possible to induce a blender-like flow around the outside of the chamber (similar, I think, to how Vera's fans work). The only fear I have is that this mixing system might also become an ignition system, since it produces large amounts of ozone.
Any thoughts?
Bladeless fans in hybrids?
It's the motor that takes a beating. How about a magnetic coupling right through the walls of the main chamber? motor remains outside. The fan rotor has a small bearing and a couple of Neo magnets to transmit power. Would work great with aluminum and non-metalic guns.

This is how we do it in the lab, the only thing that goes inside the flask is a teflon coated magnet:USGF wrote:It's the motor that takes a beating.

It's possible, but remember how ion fans and lifters work.
Basically, a sharp electrode that can easily leak current, and a blunt one for the now-charged air molecules to be drawn toward.
As you increase the distance between the two, the ion wind effect becomes less and less noticeable(it happens pretty rapidly with distance). The same thing happens when you pack additional atmospheres between them, aka increase the mix pressure. Your fan will have to be 'tuned' to a certain mix; too low and you've got an arc occurring, too high and the fan will be less efficient or stop working.

Ahhhh after thinking about this a bit I can see how you could drive a fan or stirring system with a magnetic-stirrer type of setup.
Does added turbulence bring any danger of DDT?

It would be cute to (say) run your gizmo at 10 kV to mix and then bump it to 20 kV to fire. I say cute because it's...well... cute to be able to have multi-function components.saefroch wrote:Any thoughts?
HOWEVER... I see all sorts of potential problems and for what... To avoid having to use a fan that can be made almost arbitrarily rugged?
In sum: I see a sexy solution looking for a problem.
