  2. Spacecraft electric propulsion - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_electric_propulsion

    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. [1] The propulsion system is controlled by power electronics.

  3. Magnetoplasmadynamic thruster - Wikipedia

    en.wikipedia.org/wiki/Magnetoplasmadynamic_thruster

    An MPD thruster was tested on board the Japanese Space Flyer Unit as part of EPEX (Electric Propulsion Experiment) that was launched March 18, 1995 and retrieved by space shuttle mission STS-72 January 20, 1996. To date, it is the only operational MPD thruster to have flown in space as a propulsion system.

  4. Magnetohydrodynamic drive - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_drive

    A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics. The fluid is directed to the rear and as a reaction, the vehicle accelerates forward. [1] [2]

  5. Ion thruster - Wikipedia

    en.wikipedia.org/wiki/Ion_thruster

    This was the first use of electric propulsion as the interplanetary propulsion system on a science mission. [25] Based on the NASA design criteria, Hughes Research Labs developed the Xenon Ion Propulsion System (XIPS) for performing station keeping on geosynchronous satellites. [99] Hughes (EDD) manufactured the NSTAR thruster used on the ...

    en.wikipedia.org/wiki/Spacecraft_propulsion

    With a conventional chemical propulsion system, 2% of a rocket's total mass might make it to the destination, with the other 98% having been consumed as fuel. With an electric propulsion system, 70% of what's aboard in low Earth orbit can make it to a deep-space destination. [24] However, there is a trade-off.

  7. Plasma propulsion engine - Wikipedia

    en.wikipedia.org/wiki/Plasma_propulsion_engine

    A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma. This is in contrast with ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids/anodes. These exist in many forms (see electric ...

  8. Hybrid vehicle drivetrain - Wikipedia

    en.wikipedia.org/wiki/Hybrid_vehicle_drivetrain

    Combustion-electric (CE) hybrids have battery packs with far larger capacity than a combustion-only vehicle. A combustion-electric hybrid has batteries that are light that offer higher energy density and are far more costly. ICEs require only a battery large enough to operate the electrical system and ignite the engine. [1]

  9. Electric aircraft - Wikipedia

    en.wikipedia.org/wiki/Electric_aircraft

    The NASA Electric Aircraft Testbed (NEAT) is a NASA reconfigurable testbed in Plum Brook Station, Ohio, used to design, develop, assemble and test electric aircraft power systems, from a small, one or two person aircraft up to 20 MW (27,000 hp) airliners. [84] NASA research agreements (NRA) are granted to develop electric-propulsion components ...
