    Spacecraft electric propulsion - Wikipedia

    • Spacecraft electric propulsion (or just electric propulsion) is a type of spacecraft propulsion technique that uses electrostatic or electromagnetic fields to accelerate mass to high speed and thus generating thrust to modify the velocity of a spacecraft in orbit. The propulsion system is controlled by power electronics. Electric thrusters typically use much less p… 展开

    History

    The idea of electric propulsion for spacecraft was introduced in 1911 by Konstantin Tsiolkovsky. Earlier, Robert Goddard h… 展开

    Types

    These types of rocket-like reaction engines use electric energy to obtain thrust from propellant.
    Electric propulsion thrusters for spacecraft may be grouped into three families based on the type of for… 展开

    Dynamic properties

    Electrically powered rocket engines provide lower thrust compared to chemical rockets by several orders of magnitude because of the limited electrical power available in a spacecraft. A chemical rocket imparts energy to the co… 展开

    What type of engine does a spacecraft use?
    In chronological order, spacecraft are listed equipped with electric space propulsion. This includes both cruise engines and/or thrusters for attitude and orbit control. It is not specified whether the given engine is the sole means of propulsion or whether other types of engine are also used on a spacecraft.

    Is a high-power electric propulsion better for a specific mission?
    It can be seen from Fig. 8 (a)– (c) that the payload ratio is the same, the specific mass ratio of high-power electric propulsion increases rapidly with Pe / M i and decreases gradually after reaching the maximum value. In other words, the larger the nuclear propulsion power Pe is not always better for a specific mission.

    Are electric propulsion vehicles more powerful than chemical propulsion systems?
    Although electric propulsion vehicles have low thrust to mass ratios, they can have a larger total amount of impulse (the product of specific impulse and propellant mass, equal to the total change of momentum) than a chemical propulsion system.

    Are electric propulsion systems energy limited?
    However, because the propellants are their own energy source, the rate at which energy can be supplied to the propellant (which is ultimately limited by reaction kinetics) is independent of the mass of propellant, so very high powers and thrust levels can be achieved. Electric propulsion systems are not energy limited.
