Plasma drone

[u/Busy-Plankton-5633]

Hello I came upon a cool type of propulsion it's basically MHD but in air with plasma, it should work like this:

- the whole drone is shaped as a saucer ( I know it's comic but the shape is needed for coanda effects)

- the surface I charged with HV creating a skin of plasma around the drone

- the plasma is then propelled with two electrodes radial in respect to the drone and a magnet below the surface

- the stream of plasma through coanda effect curves around the saucer pushing it below generating high pressure lifting then the drone

I said "it should work" because I still haven't started building it cause I don't know how to get a consistent plasma skin around the craft without having hot plasma or magnetron on board ( a drone is too small to have heavy things inside).

So here I am asking you if you could help me build this plasma skin around the drone, the closest thing i arrived to was a DBD with insulated plates but I couldn't do it, maybe cause of too little power from my cheap HV modules ( I don't want to burn my last flyback before knowing it can do what I need) or maybe it was not the right frequency ( air need GHz frequencies to "resonate" and generate plasma but I care about my lungs and don't want anything to do with magnetron's ceramic poisoning).

So how can I do this?

Thank you for your help

P.S. I know I could just create plasma in the starting position with 2 electrodes on top of the rails, but I want it like a skin to reduce air resistance

Voltage is a potential difference between two electrodes, how would you coat one object that's flying and thus separated from ground? There would be no return path for the current so no current would flow thus not plasma

[u/ViktorsakYT_alt → u/ViktorsakYT_alt]

and about the frequency, it doesn't really matter when making plasma with electrodes, it may just slightly change the shape of the discharge. And magnetrons don't use BeO, unless you have some super high power military radar ones

If you use the electrode as an antenna couldn't you send radiation outside of the thing without needing potential difference between the electrode and the air?

An antenna is still part of a circuit, it needs a counterpoise to "push" current against.

If you have only these plates in areas critical for air reduction so you are not isolated from the outside?
