The thruster uses massive parallelism in its energy storage unit (ESU) design, assembling COTS components into discrete modular capacitor assemblies while maintaining low per-cap specific current … A pulsed plasma thruster (PPT), also known as a plasma jet engine, is a form of electric spacecraft propulsion. PPTs are generally considered the simplest form of electric spacecraft propulsion and were the first form of electric propulsion to be flown in space, having flown on two Soviet probes (Zond 2 and … See more Most PPTs use a solid material (normally PTFE, more commonly known as Teflon) for propellant, although very few use liquid or gaseous propellants. The first stage in PPT operation involves an arc of electricity passing through the … See more PPTs are well-suited to uses on relatively small spacecraft with a mass of less than 100 kg (particularly CubeSats) for roles such as attitude control, station keeping, de-orbiting manoeuvres and deep space exploration. Using PPTs could double the life-span of these … See more • "Design of a High-energy, Two-stage Pulsed Plasma Thruster". Princeton University. Archived from the original on 2024-08-08.
