Pulsed plasma thrusters use an arc of electric current adjacent to a solid propellant (almost always teflon), to produce a quick and repeatable burst of impulse. PPTs are great for attitude control, and for main propulsion on particularly small spacecraft with a surplus of electricity (those in the hundred-kilogram or less category). However they are also one of the least efficient electric propulsion systems, with a thrust efficiency of less than 10%. Jump to: navigation, search Teflon is the brand name of a polymer compound discovered by Roy J. Plunkett (1910–1994) of DuPont in 1938 and introduced as a commercial product in 1946. ...

Pulsed plasma thrusters were the first electric propulsion system to be deployed in space, on the Soviet probes Zond-2 in 1964 and Zond-3 in 1965. Used as an experimental system for spacecraft orientation control, Soviet engineers subsequently returned to the use of high-pressure nitrogen jets. Mars 3MV-4A Zond 2, a member of the Soviet Zond program, was the second Soviet spacecraft to attempt a flyby of Mars. ...

Design of a High-energy, Two-stage Pulsed Plasma Thrust
Pulsedplasmathrusters are a method of spacecraft propulsion which use an arc of electric current adjacent to a solid propellant (almost always teflon), to produce a quick and repeatable burst of impulse.
Pulsedplasmathrusters were the first electric propulsion system to be deployed in space, on the Soviet probes Zond-2 in 1964 and Zond-3 in 1965.
Pulsedplasmathrusters were flown in November, 2000 as a flight experiment on the NASA Goddard Space Flight Center EO-1 spacecraft.
