ENGINE WITH CLOSED DRIFT OF ELECTRONS Russian patent published in 2015 - IPC F03H1/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to electric rocket engines. Proposed engine comprises electromagnet, magnetic core with poles, anode and neutralizer cathode rigidly coupled with magnetic core and circular discharge chamber secured at the flange spring-loaded relative to magnetic core, while flange with circular discharge chamber secured thereat is coupled with the rod. Opposite end of said rod is connected with magnetic core. Note here that said rod is made of material with creep rate equal to linear rate of discharge chamber wall erosion.

EFFECT: continuous recovery of discharge chamber geometry, longer life, keeping high operating performances.
