DEVICE FOR EVACUATION OF MASS RATE OF FUEL Russian patent published in 2006 - IPC F02C9/26 

FIELD: turbojet engines.

SUBSTANCE: invention relates to device for estimating mass flow rate of liquid medium for combustion chamber which contains flow rate meter and device for determining measured position of meter. Device contains also mass flow rate meter, hybridization device to determine actual mass flow rate of liquid medium which has first input with some preset value WFcons, Xcons, prediction module to determine, basing on said first input and variable, values of state containing actual mass flow rate WFréel and parametric errors IP, assessed values ^WFdéb, ^Xdos, second input containing value of measured position of meter Xdos and measured value of mass flow rate of liquid medium WFdéb, calculator of remnants for determining remnant Rdos between measured position of meter and estimated position of said meter and remnant Rdéb between measured mass flow rate of liquid medium and assessed value of mass flow rate of said liquid medium, correction module for determining, on base of first and second remnants, correcting signals designed for application to variable value of state WFréel, IP.

EFFECT: increased accuracy of device.
