High pressure and very high temperature ionized gas generator

摘要

the generator of ionised gas to supersonic flow).;the generator unit comprises modules (11, 12, 13, 14), including:two coaxial electrodes (22, 23) of the cylindrical shape.the lower electrode (23) is open and through which the flow medium (30); - to introduce a gas vortex in planes perpendicular to the common axis of the electrodes.the gas thus injected through an electric arc (26), which is therefore an elongated; means (27) for initiation of the arc (26) between the two coaxial electrodes 22.23); means (35) for the cooling of the electrodes, a gas injection device (30), a coupling chamber (15) and coils (44) forming.around the first electrode (22), an input magnetic field, moving the foot of the bow (26) on the inner surface of the upper electrode (22).;application to tests of thermal protection materials.
