Purpose and Goals:
Create improved pulsed power driver technology for a long- life,
high efficiency electric thruster system for space use. PIT
systems don’t require electrodes which are prone to erosion in
other electromagnetic propulsion systems. Tests will confirm
thrust, Isp and efficiency. Elements of the technology that are
being demonstrated include the Vector Inversion Generator (VIG)
and the Dual Resonant Pulse Transformer (DRPT). Both have been
shown to work as designed. Next steps include developing the
magnetic switch technology and doing subscale testing.
Description:
Expected Isp of >6000 s, efficiency of 75% and
power requirements as low as 10 kW. Thrust depends on size and
repetition rate of the Pulsed Inductive Thruster (PIT) and will
be in the range of 1 to 20 N. Pulse repetition rates of a VIG of
10 Hz have been demonstrated for more than a day. More testing
at longer times and higher rates is beginning System will be
scalable from kW to MW and have a specific mass < 5 kg/ kW.
Testing of the DRPT has yielded efficiencies in excess of 98%.
