【 摘 要 】

One of the promising applications of magneto-plasma compressor (MPC) may be the use of plasma jets generated by MPC for experimental study of hypersonic flow around the models. For the study the MPC was developed with a caliber of 24 mm with internal initiation of discharge, working in "submerged" mode. The maximum operating value of the discharge current in this MPC corresponds 29 kA, the duration of the current pulse is not less than 90 μs. Jet quasi-stationary mode is set when the discharge current reaches of about 12-15 kA, that gives an estimate of the jet lifetime about 55-60 μs. To estimate the abilities of MPC the tests were conducted with Teflon conic models with a diameter of 10 mm and a height of 30 mm at a distance from the edge of the cone to the MPC nozzle exit 30-50 mm. Experiments have shown that the studied type of the MPC could serve as a basis for creation of the experimental stand for the radio physical researches of the processes in hypersonic flows in the ranges of pressures and flow rates of interest.
