66th Annual Gaseous Electronics Conference Princeton, New Jersey, October 2013

The presentation of « Successful experiments on an external MHD Accelerator: wall confinement of the plasma, annihilation of the electrothermal instability by magnetic gradient inversion, creation of a stable spiral current pattern » was accepted by t66th Annual Gaseous Electronics Conference Princeton, New Jersey was held from September 30th to October 4th 2013.

Abstract :

« 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 around a 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. »

« 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.

25th Symposium on Plasma Physics and Technology Prague June 2012

This event set up by the Czech Technical University (Faculty of Electrical Engineering, Department of Physics) and theInstitute of Plasma Physics AS CR, v.v.i., was held from June 18th to 21st 2012. We were invited to report on our MHD research works led at the Lambda Laboratory and present our last result « Velikhov Electrothermal Instability Cancellation by Modification of Electrical Conductivity Value in a Streamer by Magnetic Confinement«
