For the purposes of the MPD thruster a typical propellant is hydrogen gas, which does not normally conduct electricity. If hydrogen was going to be the “round. In theory, magnetoplasmadynamic (MPD) thrusters could produce extremely high specific impulses (Isp) with an exhaust velocity of up to and. Ion Engines and, as we will see, Electrospray Thrusters are electrostatic devices, Magneto Plasma Dynamic (MPD) thrusters: The most powerful type, with self-.

Theoretically MPD thrusters can provide high thrust with extremely high specific impulse. What problems currently prevent this technology from being used in space exploration?
My Electric Engine – Magnetoplasmadynamic Thruster
maagnetoplasmadynamic So yes, it would be great for space applications. The crazy things take a lot of power. As in a lot. Here’s the gist of the problem, from this paper:.
Magnetoplasmaynamic the thruster is operated below kWthe self-induced magnetic field becomes only marginally sufficient to provide the desired body force, and external fields are frequently added to enhance performance in this range.
Of course, spacecraft wouldn’t be able to add the external field in an efficient manner – at this point, it would be more power efficient to use another option. The paper is a great resource on the subject – there are many more nice little gems in it that I didn’t cover here.
Home Questions Tags Users Unanswered. What are the main problems with magneto plasma dynamic MPD thrusters? Is there any planned mission which will use MPD thrusters?
Michele 4 Here’s the gist of the problem, from this paper: Deer Hunter 8, 2 38 If you want this magnetopalsmadynamic of performance, you need to solve the problem of providing the power source firstsince that problem is much more expensive to solve. Playing around with plasma thrusters is fun and relatively cheap, but it is completely pointless unless you’re working on a power source.
