Ionic thrust engine
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. … 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) emitted from a radioisotope uni-directionally through a hole in its chamber. A neutralising electron gun would produce a tiny … 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 energy ratio. In addition, the propellant should not erode the thruster to … Meer weergeven Web30 jun. 2024 · Ion engines produce very little thrust, so in order to reach speeds of 100km/s they must accelerate continuously for months or years. The Dawn spacecraft, for example, was built with three redundant ion thrusters to extend its lifetime, and got nowhere near 100km/s; it carried enough propellant to change its speed by about 10km/s, and …
