    High Power Electric Propulsion (HiPEP) is a variation of ion thruster for use in nuclear electric propulsion applications. It was ground-tested in by NASA and was intended for use on the Jupiter Icy Moons Orbiter, which was canceled in Oppose The common name would appear to be Ion Thruster which in fact the article quoted above supports; "Thruster" and even "Engine" are used more times in it than "Drive". This is particularly true when talking about real technology which the wiki article is primarily concerned with rather than for example terminology from science fiction.

    The two-stage bismuth thruster technology has several advantages for high-power operation compared with conventional single-stage Hall thrusters and high-power gas-fed gridded ion thrusters. These advantages include operation at high specific impulse, high thrust density, low propellant cost, and reduced pumping speed requirements for ground Cited by: Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to.

      Since the nanosatellite business is a commercial market, the relevant propulsion technology was quickly developed, with many ideas such as the Micro-Cathode Arc Thruster (by the George Washington University) with recent flight heritage, 22 the BIT-3 tiny ion thruster (by Busek) designated for the lunar IceCube mission, 23 the CubeSat Ambipolar Cited by: 7.

Fundamentals of Electric Propulsion: Ion and Hall Thrusters March The research described in this publication was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.

Reference herein to any specific commercial product, process, or service. High Power Electric Propulsion (HiPEP) is a variation of ion thruster for use in nuclear electric propulsion applications. [1] [2] [3] It was ground-tested in by NASA and was intended for use on the Jupiter Icy Moons Orbiter, which was canceled in 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.

of a high power, high specific impulse propulsion system. Initial analyses show that high power gridded ion thrusters could satisfy JIMO mission requirements. A NASA GRC-led team is developing a large area, high specific impulse, nominally 25 kW ion thruster to satisfy both the performance and the lifetime requirements for this proposed mission.

This blog began when Ms. M.W. sent the following article to me, about NASA's recent test of the ion-Hall thruster, which has now demonstrated a thrust in excess of five newtons, far surpassing that of NASA's Dawn spacecraft, which indeed does use an ion thruster, but one only generating 90 micronewtons of thrust.

An innovative electrostatic ion thruster design, based on inertial electrostatic confinement (IEC) technology, is proposed for use as a {endash}W satellite thruster. The IEC thruster employs a spherical configuration, wherein ions are generated and accelerated towards the center of a spherical vacuum chamber.

Muhannad Eladl (US citizen) received a B.S. in Aerospace Engineering from the Georgia Institute of Technology in He started in the lab as an undergraduate student in and as a graduate student in His primary interest is in non-invasive plasma diagnostic techniques and facility effects for high-power electric propulsion devices.

All tests were conducted on a 30 cm ion thruster that was nearly identical to the NASA Solar Electric Propulsion Technology Application Readiness (NSTAR) thruster design.

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.

This was an early design, and one that was used due to the limitations of the knowledge and technology to do away with the grids. However, it’s possible that a hybrid Hall-gridded ion thruster may offer higher specific impulse while taking advantage of the more efficient ionization of an SPT thruster.
