Magnetized cold plasma experiments in arc and glow discharge regimes under low air pressure conditions in a vacuum chamber, conducted by physicist Jean-Pierre Petit in the lab circa 1975. The disc and spherical models simulate the plasma behavior around external-flow MHD accelerators, that Dr. Petit calls "MHD aerodynes". The last model is electrodeless (induction MHD aerodyne) and excites the surrounding air with high frequency HV coils. In real life conditions (ambient air pressure and 5 to 10-meter diameter full scale model) the conductive colorful plasma skin surrounding the vehicle would be generated using 2.5–3.0 GHz microwaves emitted through the fuselage.
