The SAINT Glow Discharge Plasma Jet


Since ANGEL is a composite aerospacecraft, intended to be capable of flight in the atmosphere and in space, an additional propulsion system was required. Inspired by the work of various researchers into Plasma physics, one of whom works at the JET (Joint European Torus) Fusion Reactor Laboratory in Culham, Oxfordshire (UK), the SAINT system is intended to bridge the gap.

The system works in a manner similar to a conventional EHD thruster, with some interesting add-ons. Air flow enters the front of the Jet, and reaches the OAUGDP solenoid at the centre. There, it is strongly ionised by the oscillating AC current flowing through it. This current is oscillating at approximatelt 6.7kHz and around 15 kilovolts. Ionised particles will react to a magnetic field, and this is the next component of the SAINT system. By passing a high current (30+ Amperes) through the outer solenoid, a furious magnetic field is created. The ionised particles forming the cold plasma are accelerated in the field and exit at the back of the jet, hugely accelerated. With four of these on the body of ANGEL, the thrust obtained, as you may imagine, will be quite considerable.

I have yet to buil any of these devices, as i am having a little trouble here getting the parts that I require. I am however confident that a full-up propulsive test of ANGEL will be possibel by summer, with flight tests conducted towards the autumn. The SAINT system will not function in vacuum obviously, but is capable of considerable power in the air, providing the mainstay of the thrust to escape Earth's gravity well, along with the conventional Biefeld-Brown wing and the GWS system. Once in space, the Massive-K wing alone will be enough to accelerate ANGEL to it's full cruising velocity (still being determined).
