A selffield magnetoplasmadynamic mpd thruster is a lowthrust electric propulsion spacesystem that enables the usage of magnetohydrodynamic mhd principles for accelerating a. Subsequent axial expansion combined with the direct axial acceleration, yields to exhaust plume velocities in the order of 10 1. Find materials for this course in the pages linked along the left. Energies free fulltext particle simulation model for. Once existing only in the realm of science fiction, electric propulsion has proven to be an excellent option for the future of space exploration. One of the videoed trials of my mpdt, using argon propellant and a 16unit capacitor bank. Of the different types of this propulsion the appliedfield magnetoplasmadynamic thruster apmpd seems to be the best. In theory, magnetoplasmadynamic mpd thrusters could produce extremely high specific impulses isp with an exhaust velocity of up to and beyond 110,000 ms 0.

Power at the hundreds of kilowatts and megawatt levels would be great for magnetoplasmadynamic thrusters. Magnetoplasmadynamic thruster pdf posted on april 17, 2020 by admin for the purposes of the mpd thruster a typical propellant is hydrogen gas, which does not normally conduct electricity. The particles are then propelled by the lorentz force resulting from the interaction between the current flowing through the plasma and the magnetic field which is either externally applied, or induced by the current out through the exhaust magneotplasmadynamic. 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. The magnetoplasmadynamic mpd thruster is currently the most powerful form of electromagnetic propulsion. Magnetoplasmadynamic thrusters can have hundreds of times. Magnetoplasmadynamic thrusters nasa facts national aeronautics and space administration glenn research center cleveland, ohio 4453191 fs200411022grc introduction once existing only in the realm of science fiction, electric propulsion has proven to be an excellent option for the future of space exploration. Session plasma accelerators magnetoplasmadynamic mpd. Plasma accelerators magnetoplasmadynamic mpd thrusters ion engines and, as we will see, electrospray thrusters are electrostatic devices, because the electrostatic forces that accelerate the ions or droplets are also directly felt by some electrode, and this is how the structure receives thrust. Technology and application aspects of applied field.
