ENGINE WITH CLOSED DRIFT OF ELECTRONS Russian patent published in 2014 - IPC F03H99/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to electric rocket engines. Proposed engine comprises discharge chamber with gas distribution anode. Said anode is connected via pipe with working body feed system. Engine comprises also the magnetic system with magnetic poles. This system has through chamber arranged in engine axis. Note here that thermal cathode is not connected with working body feed system. Engine incorporates at least one cathode tube and two anode tubes. Anode thermal tubes fitted in gas distribution anode are directed opposite en engine outlet. Note also that anode thermal tubes surround cathode thermal tube at their tail section. Cathode thermal tube extends through engine through chamber and is arranged with clearance relative to cathode nonworking side. Cathode thermal tube is electrically isolated from cathode. Start heater is arranged at tail part on inner side of anode thermal tubes. Said heater surrounds said cathode thermal tube. Heat shields are mounted outside the anode thermal tube and in cathode thermal tube part adjoining the cathode. Heat shields envelope the anode thermal tubes.

EFFECT: higher engine efficiency and reliability.
