ON-BOARD FUEL GAUGING SYSTEM WITH COMPENSATION IN FUEL CHARACTERISTIC PARAMETERS Russian patent published in 2002 - IPC

FIELD: aircraft instrumentation engineering; measurement of mass of fuel carried on board maneuverable aircraft. SUBSTANCE: proposed system includes sensors and indicator showing parameters of fuel stored in aircraft tanks: indicator of suspending and dropping first usage tanks auxiliary tanks, sensors of flow rate of fuel being used and characteristic parameters of fuel. System includes fuel data processing units and indicator. For effective compensation of error of measurement of mass of fuel, characteristic parameter sensor employs three different meters of fuel parameters: fuel temperature meter, meter of static dielectric fuel permeability measured at DC or low-frequency AC and meter of dynamic dielectric fuel permeability measured at high-frequency AC. EFFECT: enhanced accuracy of measurements at space evolutions and loads, as well as during in-flight refueling. 4 cl, 1 dwg
