METHOD FOR CONTROL OF IONISATION PLASMA FLOW DURING ADJUSTMENT OF THRUST IN LOW-THRUST ELECTROJET ENGINE

摘要

FIELD: power engineering.;SUBSTANCE: method for control of ionisation plasma flow during adjustment of thrust in low-thrust electrojet engine is based on change of plasma ionisation extent, defining value of flow pulling thrust force, therefore, high-frequency electric field is developed for exposure of ionisation plasma, field-caused mechanical oscillations of plasma with the same frequency are measured, and converted signal is used to change speed and value of flow to obtain maximum amplitude of mechanical oscillations of plasma and maximum extent of its ionisation.;EFFECT: invention makes it possible to increase engine efficiency factor and to reduce flow of working fluid during engine thrust adjustment.;1 dwg
