A thrust formula for an MPD thruster with applied-magnetic field

In this paper a thrust formula for applied field MPD will be presented. The swirling velocity will be derived from the magnetic stress tensor and its conversion into axial energy into the magnetic nozzle will be analytically treated. The theoretical prediction of both swirling velocity and thrust will be compared to the measurements showing a reasonable agreement.

► A analytical formula to predict the thrust of an MPD with applied field derived.
► Comparison between predictions and measurements.
► Satisfactory agreement with experiments considering the model hypotheses.
