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. Retrieved 2024-06-27. • "EO1 Pulsed Plasma Thruster" See more The equation for the change in velocity of a spacecraft is given by the rocket equation as follows: See more PPTs are very robust due to their inherently simple design (relative to other electric spacecraft propulsion techniques). As an electric propulsion system, PPTs benefit from reduced fuel consumption compared to traditional chemical rockets, reducing launch … See more • Vacuum arc thruster See more WebThe Metal Plasma Thruster was developed by Alameda Applied Sciences Corporation over the span of a decade. With consistent NASA support along the way, variations of plasma physics and system architecture led to a flight-ready system, with an upcoming radiation hardened configuration being prepared for full qualification.
