N2 - The present work is devoted to experimental investigations of the possibilities of Quasi-Stationary Magneto Plasma Compressor (MPC) application to plasmadynamics and aerodynamics. MPC operates in two main regimes. The first is a "Vacuum Regime" (VR). In this regime MPC operates under the initial pressure nearly 10-5 Torr, and the fast impulse valve is used to let the gas pass into MPC. In this regime MPC can produce a compressive quasi-stationary plasma jets of very high velocity (about 70-100 km/s for He), but with comparatively low density (1015-10-16 cm -3). The second regime is a residual gas regime (RGR). In this one MPC operates with residual gas, containing in test chamber, and does not need in fast gas valve. The initial pressure for this regime is usually 0.1-10 Torr. The plasma jets in this regime have the life time and geometry as in VR case, comparatively low velocities (5-20km/s for air) and high densities (10 17-1018 cm-3). MPC in RGR possesses very high dynamic pressure (our preliminary estimations give the value about 100-150 bar) and high mass flow rate (about 50 g/s). Results of our first experiments show that RG regime of MPC is perspective for experimental modeling of interaction processes of high-speed plasma flows with different materials and bodies and for studying of mixing of supersonic neutral flows and hypersonic plasma jets, plasma injection in standard aerodynamic supersonic flows.
