Ion Thrusters

Some articles on ion thrusters, ion thruster, ions, thrusters:

Ion Thruster - Lifetime
... A major limiting factor of ion thrusters is their small thrust however, it is generated at a high propellant efficiency (mass utilisation, specific impulse) ... The low thrust requires ion thrusters to provide continuous thrust for a long time to achieve the needed change in velocity (delta-v) for a particular mission ... To cause enough change in momentum, ion thrusters are designed to last for periods of weeks to years ...
Ion Thruster
... An ion thruster is a form of electric propulsion used for spacecraft propulsion that creates thrust by accelerating ions ... The term is strictly used to refer to gridded ion thrusters, but may often more loosely be applied to all electric propulsion systems that accelerate plasma, since plasma consists of ions ... Ion thrusters are categorized by how they accelerate the ions, using either electrostatic or electromagnetic force ...
Ion Thruster - Missions - Planned Missions
... In addition, several missions are planned to use ion thrusters in the next few years ... It uses ion thrusters in combination with swing-bys to get to Mercury, where a chemical rocket will be fired for orbit insertion ... It will not use ion thrusters as its primary propulsion system, but will use both colloid thrusters and FEEP for very precise altitude control—the low thrusts of these ...
Vehicle - Locomotion - Motors and Engines
... Ion thrusters are used on some satellites and spacecraft ... Ion thrusters run primarily off electricity but they also need a propellant such as caesium or more recently xenon ... Ion thrusters can achieve extremely high speeds and use little propellant however the are power hungry too ...
Electrostatic Ion Thrusters - Gridded Electrostatic Ion Thrusters
... See also electrostatic ion thruster Gridded electrostatic ion thrusters commonly utilize xenon gas ... in the electrical field of the cathode, fall to the anode (Kaufman type ion thruster) ... discharge and omits any cathode (radio frequency ion thruster) ...
