Abstract

Un procédé de fabrication d'un propulseur électrique à effet Hall magnétiquement non écranté comprenant un canal de décharge annulaire radialement disposé un pôle magnétique interne et un pôle magnétique externe et comprenant une paroi de fond radiale à partir de laquelle s'étendent axialement une paroi interne et une paroi externe. Le procédé comprend : - une détermination (300) d'une zone d'ionisation moyenne d'ergol dans le canal de décharge, et une détermination (305) d'une ligne de champ magnétique traversant ladite zone, - une estimation (310 et 315) de premier et second seuils de positionnement (hi et he) correspondant à la distance séparant, selon la direction axiale, la paroi de fond du croisement de ladite ligne de champ magnétique avec, respectivement, la paroi interne et la paroi externe, et - un positionnement (320 et 325) axial des poles magnétiques interne et externe à une distance de la paroi de fond inférieure respectivement au premier seuil de positionnement (hi) et au second seuil de positionnement (he).A method of manufacturing a magnetically unsshielded electric Hall effect thruster comprising a radially annular discharge channel disposed an inner magnetic pole and an outer magnetic pole and comprising a radial bottom wall from which axially extend an inner wall and an outer wall. The method comprises: - a determination (300) of an average ionization zone of propellant in the discharge channel, and a determination (305) of a magnetic field line crossing said zone, - an estimate (310 and 315) of first and second positioning thresholds (hi and he) corresponding to the distance separating, in the axial direction, the bottom wall from the crossing of said magnetic field line with, respectively, the inner wall and the outer wall, and - An axial positioning (320 and 325) of the internal and external magnetic poles at a distance from the bottom wall below respectively the first positioning threshold (hi) and the second positioning threshold (he).
