An ion thruster produces a flow of air even though it has no moving parts. A version of this seemingly impossible device is used on a larger scale to propel deep space probes for NASA.

The advantage to this system over others is that you need only an electrical source to power the device and it has no moving parts so it is almost : Alexander Reifsnyder. In this capacity, REP would principally be used as an interplanetary stage.

An effort is on-going to examine scaling relationships and design criteria for ion propulsion systems, and to address the need for a light weight, low power. This original book discloses a new and much faster "slip through the cracks" approach to outer space propulsion. By using fluid drive propulsion this new self-enclosed engine is a revolutionary form of micro-gravity propulsion which electromagnetically accelerates a liquid metal through a geometric structure at high speed, thus creating a dynamic inertial force propulsion.1/5(2).

space-charge limitation arises in this type of thruster (as opposed to gridded ion thrusters), and the acceleration distance can be several cm, compared to the typical −1 mm gap used in ion engines.

This flexibility is one of the main advantages of the Hall thruster, removingFile Size: KB. A review of the development status of electric thrusters in the electrothermal, electrostatic, and electromagnetic categories suggests that low-power ion thrusters and arcjets have been developed and tested to a level that they are now ready for flight use in performing on-orbit stationkeeping.

This contribution presents a short review of electric propulsion (EP) technologies for satellites and spacecraft. Electric thrusters, also termed ion or plasma thrusters, deliver a low thrust level compared to their chemical counterparts, but they offer significant advantages for in-space propulsion as energy is uncoupled to the propellant, therefore allowing for large energy by: Electric Propulsion Options and Trades • Benefits: • Much higher specific impulse • Arcjets – s • Hall Thrusters – – s • Ion thrusters – – 10,s • Other concepts (VASIMIR, MPD, PIT) in same range • Higher Isp results in much lower propellant mass • Trades: • Need external source of power and electronics to match to the thruster.

A 30 cm diameter xenon ion thruster is under development at NASA to provide an ion propulsion option for missions of national interest and it is an element of the NASA Solar Electric Propulsion Technology Applications Readiness (NSTAR) program established to validate ion propulsion for space flight applications.

Electric propulsion (EP) today features a range of mature and well-established technologies for moving satellites and spacecraft in space. The development of EP dates back to the s, with the appearance of plasma sources capable of delivering substantial current [].The first in-space demonstrations of EP occurred in and were achieved with an ion engine aboard the Cited by: An ion thruster or ion drive is a form of electric propulsion used for spacecraft creates thrust by accelerating ions using electricity.

An ion thruster ionizes a neutral gas by extracting some electrons out of atoms, creating a cloud of positive ion thrusters rely mainly on electrostatics as ions are accelerated by the Coulomb force along an electric field. for ECR thruster development.
