“…The measurement has been done using ten N II spectral lines intensities. It was found that during quasistationary phase in the CPF region the average temperature is 35 000 K, what is in good agreement with the results obtained in previous experiments [8,9]. From Fig.…”

Magnetoplasma compressor with a semi-transparent electrode system that operates in the ion current transfer regime is studied. The thermodynamic parameters of the discharge and the compression plasma flow generated in N2+5 % H2 mixture at 500 Pa pressure with input energy 4.9 kJ have been measured. Special construction of the accelerator electrode system enable the electrode shielding by the self-magnetic field resulting in protection from the erosion. Fully predominant N II spectrum is observed in the compression plasma flow. The plasma flow velocity, electron temperature and electron density maximum values are measured close to 35 km/s, 4 eV and 2 × 10 16 cm −3 , respectively.

“…Almost all known MPC types operate under high vacuum conditions (10 -5 -10 mbar) with very high discharge currents (10-200 kA) and low repetition frequencies (0,01-0,1 Hz). The overall system in all cases is based on bulky high-current switchers, heavy high voltage capacitor banks with tens of kV, complex control and diagnostics devices [1][2][3][4][5][6][7]. Nevertheless, all the previous work gave the main inspiration to develop new lightweight, highly miniaturized, lower voltage powered stable MPC-based plasma jet generator systems for flow control and propulsion purposes.…”

A new breakthrough in jet propulsion technology since the invention of the jet engine is achieved. The first critical tests for future air-breathing magneto-plasma propulsion systems have been successfully completed. In this regard, it is also the first time that a pinching dense plasma focus discharge could be ignited at one atmosphere and driven in pulse mode using very fast, nanosecond electrostatic excitations to induce self-organized plasma channels for ignition of the propulsive main discharge. Depending on the capacitor voltage (200-600 V) the energy input at one atmosphere varies from 52-320 J/pulse corresponding to impulse bits from 1.2-8.0 mNs. Such a new pulsed plasma propulsion system driven with one thousand pulses per second would already have thrust-to-area ratios (50-150 kN/m²) of modern jet engines. An array of thrusters could enable future aircrafts and airships to start from ground and reach altitudes up to 50km and beyond. The needed high power could be provided by future compact plasma fusion reactors already in development by aerospace companies. The magneto-plasma compressor itself was originally developed by Russian scientists as plasma fusion device and was later miniaturized for supersonic flow control applications. So the first breakthrough is based on a spin-off plasma fusion technology.
