Studies on Dynamic Pressure of Compression Plasma Flow

The temporal evolution of dynamic pressure of a compression plasma flow, generated by a magneto-plasma compressor, was investigated in a range of initial voltages from 2 to 4.5 kV by an interferometric method. The main advantages of the method are that it is insusceptible to electromagnetic noises and mechanical vibrations, requires no calibration procedures and ensures local readings from small areas. Depending on the initial voltage, the pressure values varied from 0.7 to 16 atm
