ONBOARD FUEL METERING SYSTEM WITH COMPENSATION FOR DIELECTRIC CONSTANT Russian patent published in 2014 - IPC B64D37/00 B64C17/10 

FIELD: aircraft engineering.

SUBSTANCE: this system comprises fuel parameter transducers fitted in aircraft fuel tanks: Fuel level and dielectric constant, fuel upper and lower level indicators, onboard computer with left and right control modules, control channels and memory cells on fuel tank geometry, left and right fuel age modules, comparator and balance adjuster. Note here that dielectric constant transducers are arranged level with fuel upper level indicators. System onboard computer incorporates inputs to receive extra data from fuel flow rate transducers and aircraft undercarriage position indicator.

EFFECT: higher accuracy, validity and efficiency of measurement fuel mass store, fuel reserve supply and control over aircraft balance at standard and emergent conditions of system operation.
