6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory 3D sketch of an electromagnetic propulsion fusion plasma thruster. 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 ...
Electromagnetic propulsion (EMP) is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields. The electrical current is used to either create an opposing magnetic field, or to charge a field, which can then be repelled.
3D sketch of a electromagnetic propulsion fusion plasma thruster. A pulsed plasma thruster (PPT), also known as a Pulsed Plasma Rocket (PPR), or as a plasma jet engine (PJE), is a form of electric spacecraft propulsion. [1]
An MPD thruster during test firing 3D sketch of an electromagnetic propulsion fusion plasma thruster. A magnetoplasmadynamic (MPD) thruster (MPDT) is a form of electrically powered spacecraft propulsion which uses the Lorentz force (the force on a charged particle by an electromagnetic field) to generate thrust.
3D sketch of an electromagnetic propulsion fusion plasma thruster. VASIMR is a type of electrothermal plasma thruster/electrothermal magnetoplasma thruster. In these engines, a neutral, inert propellant is ionized and heated using radio waves. The resulting plasma is then accelerated with magnetic fields to generate thrust.
Plasma propulsion engines using magnetohydrodynamics for space exploration have also been actively studied as such electromagnetic propulsion offers high thrust and high specific impulse at the same time, and the propellant would last much longer than in chemical rockets. [14]
Electromagnetic formation flight (EMFF) investigates the concept of using electromagnets coupled with reaction wheels in place of more traditional propulsion systems to control the positions and attitudes of a number of spacecraft in close proximity. Unlike traditional propulsion systems, which use exhaustible propellants that often limit ...
This power/propulsion technology has been suggested to be used on a Pluto orbiter and lander mission, [4] [8] or as integration on the Orion spacecraft to transport a crewed mission to Mars in a faster time frame [14] [15] (4 months instead of 9 with current technology). [10] DFD is projected to deliver scientific payloads to Titan in 2.6 years ...
