BOARD fuel gauging system maneuverable plane with temperature compensation and permittivity FUEL

摘要

The invention relates to aircraft instrument and can be used to measure and reserve fuel on board the aircraft maneuvering. The proposed system comprises a counter fuel mass flow rate, installed in line issuing fuel aircraft propulsion, fuel sensors, installed in the gas and Consumables highways fuel tanks, and also in the balancing thoroughfares, highways cooling units, the return pipe and pipeline pumping of fuel, fuel level sensors and signaling the fuel level established in the fuel tanks, fuel temperature sensors and fuel permeability dielectric sensors mounted in highways and tanks of aircraft propulsion. The system also includes an onboard computer, the comparison unit, the indicator and electronic blocks: Block bypass, return unit, filling unit, refueling unit and balancing unit. On the basis of information about the fuel coming from said sensors, detectors, and the system counter, and in accordance with commands received from outside the aircraft and data about refueling embodiments, refueling and the return plane are stored in memory onboard computer, comparator and fueling units , refuel and return in the system is determined by the amount of fuel charged into the fuel tanks of the aircraft on the ground, the current stock of fuel in flight, the amount of fuel dispensed from aircraft and aero Remainder ok fuel necessary to return the aircraft. In addition, the system manages the refueling process, refueling and dispensing of fuel, as well as ensure the timely adoption of decisions by the crew of the plane returning fuel. Based on the information generated fuel flow sensors installed in the bypass highways, and mass flow meter, installed in the fuel line issuing in avionic computer system and a bypass unit and refill unit counted number of bypass and dispensed fuel,; can significantly reduce the methodological error of measurement, arising from the bypass and delivery of fuel. In case of violation of the transverse plane centering unit balancing system based on the information coming from the fuel flow sensors in the balancing highways, using data obtained from the onboard computer and the comparison device generates a balancing fuel transfer control command, allowing the aircraft to restore desired alignment.
