The presentation of « MHD Aerodynes, with wall confined plasma, electrothermal instability annihilated and stable spiral current pattern. » was accepted by the International Conference on Research and Application of Plasmas Warsaw, Poland was held from September 2nd to 6th 2013.
« MHD propulsion has been extensively studied since the fifties. To shift from propulsion to an MHD Aerodyne, one only needs to accelerate the air externally, along its outer skin, using Lorentz forces. We present a set of successful experiments, obtained on a disk-shapped model, placed in low density air. We successfully dealt with various problems : wall confinement of two-temperature plasma obtained by inversion of the magnetic pressure gradient , annihilation of the Velikhov electrothermal instability by magnetic confinement of the streamers, establishment of a stable spiral distribution of the current, obtained by an original method. Another direction of research is devoted to the study of an MHD-controlled inlet which, coupled with a turbofan engine and implying an MHD-bypass system, would extend the flight domain to hypersonic conditions.«
