METHOD FOR DEFINITION OF FLOW RATE OF SYSTEM FOR SUPPLY OF WORKING MEDIUM TO PLASMA SOURCE Russian patent published in 2010 - IPC G01F9/00 F02K9/56 F03H1/00 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement equipment used mainly under space vacuum conditions and intended for definition of flow rate of working medium (xenon) supplied from spacecraft jet engine tanks. One measures operating pressure P_in(t) in the inlet main of the plasma source 1 (propulsion module/PM/ including a stationary plasma engine), defines the transfer characteristic of the thermothrottle 10 of the execution unit 5 of the stabilisation system 4 of the discharge current I_p of the plasma source regulating supply of working medium to the plasma source providing for nominal conditions of operation, with I_p=f(I_tt), where I_tt - thermothrottle current. In the course of the plasma source operation one measures the current value of the inlet main operating pressure and thermothrottle current. By dependence one defines the current value of weight flow of working medium per unit of time.

EFFECT: invention improves flow rate definition precision.
