An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. It 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 ions. Ion thrusters are categorized as … Meer weergeven The first person who wrote a paper introducing the idea publicly was Konstantin Tsiolkovsky in 1911. The technique was recommended for near-vacuum conditions at high altitude, but thrust was … Meer weergeven Pulsed inductive thrusters Pulsed inductive thrusters (PITs) use pulses instead of continuous thrust and have the … Meer weergeven Ion thrusters' low thrust requires continuous operation for a long time to achieve the necessary change in velocity (delta-v) … Meer weergeven Ion thrusters use beams of ions (electrically charged atoms or molecules) to create thrust in accordance with momentum conservation. The method of accelerating the ions varies, but all designs take advantage of the charge/mass ratio of the ions. This … Meer weergeven Gridded electrostatic ion thrusters Gridded electrostatic ion thrusters development started in the 1960s and, since then, it has been used for commercial satellite propulsion and scientific missions. Their main feature is that the … Meer weergeven A theoretical propulsion system has been proposed, based on alpha particles (He or 2He indicating a helium ion with a +2 charge) … Meer weergeven Ionization energy represents a large percentage of the energy needed to run ion drives. The ideal propellant is thus easy to ionize and has a high mass/ionization … Meer weergeven Web23 jun. 2016 · An ion thruster produces a flow of air even though it has no moving parts.
