ON-BOARD FUEL GAUGING SYSTEM WITH COMPENSATION IN DYNAMIC DIELECTRIC FUEL PERMEABILITY Russian patent published in 2002 - IPC

FIELD: aircraft instrumentation engineering; gauging fuel mass on board of maneuverable aircraft. SUBSTANCE: proposed system includes sensors, meters and indicators showing parameters of fuel contained in aircraft tanks: indicators of suspension and dropping of tanks of first sequence of usage of fuel auxiliary tanks, sensors showing consumption of fuel and meters of dynamic dielectric permeability, sensor showing flow rate of fuel being received and meter of dynamic dielectric fuel permeability, as well as sensors showing level of fuel and meters of dynamic dielectric fuel permeability. System includes also fuel data processing units and indicator. For compensation of error of measurement especially when aircraft works on domestic fuels, system is provided with fuel density compensator meter of dynamic dielectric fuel permeability measured at high-frequency AC. EFFECT: enhanced accuracy of measurement. 4 cl, 1 dwg
