Abstract. 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.
Magneto-plasma compressors (MPC) were originally developed as quasistationary plasma accelerators for fusion applications [1, 4]. They consist of coaxial electrodes representing an electromagnetic Laval nozzle analogue [4, 8], see Figure 1. In the air regime with initial pressures from 0.1-10 Torr the plasma jet has a lifetime of 50-100 μs, can reach velocities from 5-20 km/s and high densities from 1017-1018 cm-3 [8]. In the plasma focus the pinching discharge can be compressed to pressures of about 100-150 bar [8]. High speed plasma jets generated by magneto-plasma compressors (MPC) can be applied for plasma fusion devices [1-6, 15, 26-28], high-enthalpy plasma-material interactions, surface modification [7, 15, 25, 27], supersonic flow control [8-11] and air-breathing propulsion [12-14].
