Factors for MPD Thrustors.

Abstract

The work resulted in: (a) A generalization of the classical anode depletion theory of onset to conditions below onset, giving insights as to anode drops and flow rearrangements; (b) Analytical results describing the current concentration at cathode roots due to the Hall effect, and also the axial voltage distribution in a segmented thruster with suppressed axial current; (c) Completion of our study on local plasma stability, with the conclusion that damping, mostly due to heat conduction makes is unlikely that onset can be due to a local instability. Work was initiated on a theory of flow in contoured channels. Keywords: Magnetoplasma dynamic thrusters; Electric propulsion.
