MAGNETOHYDRODYNAMIC GENERATOR Russian patent published in 2018 - IPC H02K44/08 

Abstract RU 2650887 C2

FIELD: electricity.

SUBSTANCE: magnetohydrodynamic generator (MHDG) contains a working body source, a nozzle, a magnetohydrodynamic channel (MHD-channel) with an insulating coating of the internal surface, on which several pairs of electrodes are disposed opposite to each other to remove the generated voltage, connected in parallel with the load located outside the MHD-channel. It is equipped with two additional electrodes - a field anode and a field cathode, installed opposite to each other on the inner surface of the initial section of the MHD-channel up to the area of the electrode location to remove the generated voltage. The adjustable voltage converter is connected in parallel with the load. The output of the control unit is connected to the signal input of the adjustable voltage converter. The field anode and the field cathode are connected respectively to the positive and negative poles of the adjustable voltage converter. The shells of the working body source, the nozzle and the diffuser are made of electrically conductive material. On their outer surfaces, as well as on the surface of the field cathode, which are washed by the working body during the MHDG operation, an emissive layer made of a material with a low electronic work function is deposited.

EFFECT: increased efficiency coefficient, durability and reliability.
