ion engine

A device consisting of a source for producing ions and an electromagnetic field for accelerating the ions in a particular direction. In practice, an ion engine can be used in a low-pressure environment to produce propulsion by reaction forces associated with the rapidly moving ions. It is also necessary to expel oppositely charged particles to the ions from the engine to ensure charge neutrality. Ion engines have been investigated as possible power sources for spacecraft.

ion engine

[′ī‚än ‚en·jən]
(aerospace engineering)
An engine which provides thrust by expelling accelerated or high-velocity ions; ion engines using energy provided by nuclear reactors are proposed for space vehicles.
