A pulsed plasma thruster (PPT), also known as a Pulsed Plasma Rocket (PPR), or as a plasma jet engine (PJE), is a form of electric spacecraft propulsion. [1] 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 Zond 3) starting in 1964.

American interest in gravity control propulsion research intensified during the early 1950s. Literature from that period used the terms anti-gravity, anti-gravitation, baricentric, counterbary, electrogravitics (eGrav), G-projects, gravitics, gravity control, and gravity propulsion.
A thruster during test firing Artist rendition of VASIMR plasma engine. A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma.
A nozzle releases a puff of gas which spreads across a flat spiraling induction coil of wire about 1 meter across. A bank of capacitors releases a pulse of high voltage electric current of tens of kilovolts lasting 10 microseconds into the coil, generating a radial magnetic field.
Microwave electrothermal thruster, also known as MET, is a propulsion device that converts microwave energy [1] (a type of electromagnetic radiation) into thermal (or heat) energy.
Jet propulsion is produced by some reaction engines or animals when thrust is generated by a fast moving jet of fluid in accordance with Newton's laws of motion.It is most effective when the Reynolds number is high—that is, the object being propelled is relatively large and passing through a low-viscosity medium.
In-flight picture of the pulsed-detonation–powered, and heavily modified, Rutan Long-EZ on January 31, 2008 PDEs have been considered for propulsion since 1940. [3]The first known flight of an aircraft powered by a pulse detonation engine took place at the Mojave Air & Space Port on 31 January 2008. [4]
