Presentation Transcript

  1. PIT – What it is • PIT - Pulsed Inductive Thruster • NuPIT – Nuclear Pulsed Inductive Plasma • Step after the grided ion thruster • Advantage: No Electrode • No electrode means that constant pulsing of the plasma will not lead to erroded electrode • This leads to longer run time of the thruster • Radiation is main source of damage to inductive coil

  2. Why we care • Longer life than electrode thruster • Higher Specific Impulses (2000 – 5000 s) • Efficiencies up to 50% (relatively fixed) • Why I care? • Attracted to this due to passion for NEP and this seemed to be an advancement on the standard Ion Thruster

  3. Origins & How it works • Not sure of Origin • Perhaps comes after ion thruster • How it works • Pulsed plasma uses Lorentz force to throw ions • Gas usually used is ammonia • Explain the following diagrams to describe the ionization and discharge of the plasma

  4. Diagram style

  5. Future Prospects • Attractive for deep space missions due to efficiency at delivering payloads • Has yet to fly in space • Certain requirements for this tech to be attractive • Specific mass ~ 1 kg / kW • PITs are heavy and power hungry • Need capacitors to recharge in 5 to 10 ms to satisfy this
