ELECTROJET PROPULSION DEVICE AND METHOD FOR MONITORING AND CONTROL OF TEMPERATURE IN ELECTROJET ENGINE WITH MAGNETISATION COILS Russian patent published in 2009 - IPC F03H1/00 H05H1/54 

FIELD: transportation.

SUBSTANCE: invention may be used in ground tests and operation of electrojet engines (EJE) of various capacity, for instance Hall plasma engines, and electrojet propulsion devices (EJPD) on their basis. EJPD comprises at least one EJE (1) with magnetisation coils (2), device for conversion and control (3) with controllable source of magnetisation coils power supply (4) and command-telemetric device (5), which sets current level in magnetisation coils (2). Command-telemetric device (5) is equipped with additional device (6) of voltage measurement, which is connected to magnetisation coils. In EJE (1) with magnetisation coils (2) with current fed to magnetisation coils (2), voltage drop in them is measured, EJE (1) temperature is controlled by value of electric resistance in magnetisation coils, identified from ratio of measured voltage drop in them and value of supplied current, and temperature is adjusted by changing of current value in magnetisation coils.

EFFECT: reduced weight and higher reliability of electrojet propulsion device, improved accuracy of electrojet engine temperature measurement and reduced power inputs for maintenance of required temperature mode of electrojet engines.
